Although described from a single male specimen from Riau Province (Lieftinck 1940b), P. buwaldai had not been recorded from Sumatra again until now. It had remained known only from the holotype until Hämäläinen (2000) recorded it from Sabak Bernam in Selangor, Malaysia and all later records have been from Peninsular Malaysia. The Bornean P. chrysopus Selys, 1889 is closely allied with P. buwaldai, differing significantly only in markings of the thorax. Lieftinck (1940b) states that the two species also differ “very strikingly” in the colour of the legs but this is not correct (an error arising from limited material and state of preservation of said material), in both species mature males develop luridly red legs, but this colour fades on preservation to a dull red or the “salmon-orange” described by Lieftinck (1940b).</p><p>Other remarks. Where the habitat has been recorded P. buwaldai has been found in swamp forest, in most cases (Dow et al. 2012, Choong 2013, Choong &amp; Cheah 2013) explicitly PSF. Kalkman (2004: 26) recorded the species from Tasik Chini in Pahang, at “a small, almost stagnant runnel, in a small piece of secondary swamp forest.” It is not clear if this was PSF or freshwater swamp forest but PSF is (or was) present around Tasik Chini. Lieftinck (1940b) does not state the habitat in which the holotype was collected in Riau. Hämäläinen (2000: 54) lists the species from a “black-water stream” in the Bernam swamp forest in Selangor; it can reasonably be assumed that this habitat was actually in PSF. The record in Choong, Orr &amp; Dow (2008) is based on old student collections from the Universiti Kebangsaan Malaysia (UKM) campus or its vicinity in Selangor, in the UKM collection and without any information on habitat, but pockets of low pH swamp forest were likely present on or in the vicinity of the campus in the past but have since been lost to development. All records from our study in Riau are from PSF. It appears that P. buwaldai is a specialist species of low pH swamp forest, mainly PSF. In the Kampar Peninsula all individuals found were in the forest except one individual found close to its edge in a semi-open area. The species was generally abundant during all survey periods except January 2020 (when it was still present around Sungai Serkap at least), with far more individuals seen than were collected.</p></div>	https://treatment.plazi.org/id/03DB2A41FFBAFF88FDA12419959DFD60	Public Domain	No known copyright restrictions apply.

The variety of color forms (and general variability) of C. vittata has been commented on before (for example see Dow &amp; Singa (2022) on forms found in Sarawak and Brunei) but no detailed study of C. vittata and its closest allies has been made since that of Lieftinck (1940a). Two color forms were found at the Kampar Peninsula: (a) a largely dark form with yellow legs and a very variable (sometimes very reduced) pattern of pale markings on the synthorax, this form is very common in the low pH habitats of the main part of the peninsula; (b) the ‘typical’ red-legged form, only a single individual of this form was collected, at a small stream in oil palm on mineral soils at the base of the peninsula. In Borneo typically a single form is found in a given area, for instance a yellow-legged form is found in the southwest of Sarawak (where it occurs in a variety of habitats including PSF), with an exception in Brunei and Limbang Division in northeast Sarawak where the ‘typical’ red-legged form and a black form (Orr 2003, Dow &amp; Singa 2022) both occur, but without clear partitioning by habitat. The situation in the Kampar Peninsula contrasts with that in Borneo with the two forms occurring in the Kampar Peninsula seemingly occupying different habitats. The yellow-legged form (which might be smaller, at least on average, than the ‘typical’ form but detailed measurements are needed to confirm this) present in the peninsula might be a low pH phenotype but the possibility that it is a distinct taxon cannot be excluded and further work is needed on this entire complex.</p></div>	https://treatment.plazi.org/id/03DB2A41FFB8FF8AFDBA21E0939CFC2C	Public Domain	No known copyright restrictions apply.

Until now this species was only known with certainty from the type series from Pahang. Amphicnemis hoisen might be considerably more widespread in Sumatra —the first author has seen a photograph (A. Alfarisyi personal communication 2019) of a male Amphicnemis from Bangka Island in which sufficient detail of the anal appendages can be seen to demonstrate that it is either A. hoisen or a closely allied but unnamed species. Despite the possible record from Bangka, the records from the Kampar Peninsular are the first confirmed and published records of this species from Indonesia.</p><p>In the Kampar Peninsular Amphicnemis hoisen was only found in flooded PSF adjacent to the Serkap River and its tributary Simpang Sianyir, however at the type locality in Pahang it was found at pools in otherwise unflooded PSF apparently distant from any stream or river.

Until now M. megabinluyog had only been known from the type locality in freshwater mangrove in Brunei (Dow &amp; Choong 2015). In February 2023 a single male Mortonagrion was collected at a pool just inside a stand of what appears to be mangrove near the Kampar River and was found to agree well with M. megabinluyog . In June 2023 the same stand of mangrove was entered at a different spot and a few individuals of both sexes were collected. Males agree in their anal appendages with M. megabinluyog but show some small differences in markings. Females have the posterior lobe of the prothorax more rounded in dorsal view than that shown for M. megabinluyog in fig. 6 in Dow &amp; Choong (2015) and two of the females have blue dorsal markings dorsally on abdominal S8, absent in the female paratype. None of these differences seem particularly significant, especially since variation even in the Brunei population can hardly be assessed with a type series of three males and a single female from one small site and we have little hesitation in assigning the Kampar Peninsula population to M. megabinluyog . This record is however surprising, and this species should be looked for not only in coastal areas in other parts of Borneo and Sumatra but also in Peninsular Malaysia.</p></div>	https://treatment.plazi.org/id/03DB2A41FFB1FF82FE1923DC959AF84C	Public Domain	No known copyright restrictions apply.

A series of a Mortonagrion (males only) collected in PSF in the Kampar Peninsula strongly resembles M. appendiculatum Lieftinck, 1937 (only known from Belitung) in general colouration but differs in the anal appendages. Mortonagrion forficulatum was described from present day Central Kalimantan (Lieftinck 1953b) and all of the few later records are from Central or East Kalimantan. The Kampar Peninsula taxon has very similar anal appendages to those of M. forficulatum but differs strongly in markings, in particular males from confirmed populations of M. forficulatum have only a basal blue ring on abdominal S7, with S8 blue in the apical quarter and S9–10 “wholly deep black, but 9 occasionally with a pair of small, sky-blue baso-dorsal spots” Lieftinck (1953b: 394), in contrast the Kampar taxon has larger, irregular blue marks on S7, and the dorsum of S8–9 entirely blue. The Kampar taxon was initially thought likely to be a new species, but doubts developed because of the similarity of the anal appendages with those of M. forficulatum . Recently the first author was shown photographs (inaturalist. org/observations/197961299) of an unidentified Mortonagrion from Kapuas Hulu Regency in West Kalimantan that resembles the Kampar taxon, little can be seen of the anal appendages in the photographs but what can be seen is at least similar to M. forficulatum and the Kampar taxon. There is no certain way of determining the identity of the species in the photographs without specimens, but one possibility is that it is M. forficulatum (another is that it is M. appendiculatum) and that the blue markings of the terminal abdominal segments become more extensive in the north and west of its range, in which case the Kampar population would be less atypical than it currently appears to be. In view of the uncertainty involved we have decided to leave the identity of the Kampar population open for the time being, rather than describing a new species or subspecies.</p><p>Other remarks. All specimens of this taxon were collected in PSF, either at discrete pools or (most often) in extensively but shallowly flooded sections when the water table was high. Although present in February 2023 it was more abundant in June 2023, although it was not found at high densities at any time and no specimens were collected in September/ October 2023.</p></div>	https://treatment.plazi.org/id/03DB2A41FFB6FF85FE1127B99452FAFE	Public Domain	No known copyright restrictions apply.

Dow (2010) provided the first description of the female of T. ruficollis, based on a female from Sarawak, noting that the posterior pronotal lobe had a “deep and narrow (ca 1/16 of width) central rectangular excision”, illustrating this character in his Fig. 3d. Later the first author examined a red-marked female Teinobasis in the collections of the Lee Kong Chian Natural History Museum in Singapore, collected in Singapore where the only red-marked Teinobasis recorded is T. ruficollis; this specimen lacked the excision in the posterior pronotal lobe, raising doubts over the value of this character for identification. More recently (2021–2022) the first author collected three additional females of T. ruficollis from Sarawak, two in tandem with males, all have the same excision in the posterior pronotal lobe as the female described in Dow (2010). The series from the Kampar Peninsula includes two females, both collected in tandem, one of these females lacks the pronotal lobe excision, the other has an excision, but shallower than that of the Sarawak females. It appears that the posterior pronotal lobe excision provides a diagnostic character for females of T. ruficollis in Sarawak (and quite possibly throughout Borneo) but is variably present and developed in elsewhere in its range and therefore not reliably diagnostic in general.</p><p>Remarks. Almost all Sumatran records of T. ruficollis are from satellite islands, only the record in Ris (1927) is from the mainland, but the species has also been recorded from Belitung (firstly by Lieftinck 1954), the Lingga Islands (St. Quentin 1968, as T. rajah Laidlaw, 1912 but with the male anal appendages illustrated and clearly those of T. ruficollis) and Durian Island (firstly by Lieftinck 1935a). During the surveys in the Kampar Peninsula T. ruficollis was recorded from Riau Province for the first time and proved to be moderately common in the PSF of the peninsula.</p></div>	https://treatment.plazi.org/id/03DB2A41FFB4FF86FDBE23A09721FE34	Public Domain	No known copyright restrictions apply.

During the surveys in the Kampar Peninsula a number of female Teinobasis were collected, all in PSF, which are at least very closely related to the poorly known T. suavis from Central Kalimantan. As with a very similar female recorded from Sarawak by Dow (2010), these females might actually be T. suavis (significantly increasingly the known range of that species) but until males are found the possibility that they belong to some other, undescribed, species closely allied to T. suavis cannot be ruled out.</p><p>Other remarks. The female collected in January 2020 was perched at chest height in PSF flooded by the Serkap River. Those collected in February and June 2023 were perched low and inconspicuously in vegetation to the sides of trail pools.

M3b: 1 ♂ (RER20 _ AES1; RER), 2 ♀♀ (RER20 _ AES2–3; RER), all immature, one female semi-teneral 17 i 2020; M10a: 1 ♂ (RER23 _ AES11; RER), 8 vi 2023 .</p><p>Taxonomic remarks. Eleven species of Gynacantha are known from Sundaland of which seven have been recorded from Sumatra (Dow et al. 2024). Two of these, G. dohrni and G. maclachlani, difer from the others in details of the male anal appendages and/or the absence of a well-defined T-spot on the frons. The differences between G. dohrni and G. maclachlani are subtle and have not been adequately documented. The two were both described in the same paper (Krüger 1899), G. dohrni from a male from Sumatra with an additional male from Java and three males and two females from “Nord-Borneo” (very likely referring to present day Sabah, note that for simplicity we state Sabah for these specimens hereafter), G. maclachlani from two males from Borneo: one from Sabah and the other from Brunei. The type series of both are in the Museum and Institute of Zoology, Polish Academy of Science, Warsaw, Poland (but see below). Krüger (1899) includes small, inadequate sketches of the male anal appendages of the two species in dorsal view (figs 9–10 on page 280 of Krüger 1899). Martin (1909) gave illustrations of the male anal appendages of both species, that of G. dohrni from a specimen in the Selys collection and that of G. maclachlani stated to be from a specimen in the Krüger collection so presumably one of the types; Lieftinck (1954: 101) states “ ♂ app., type ” in reference to this illustration. For G. dohrni Krüger (1899: 286) states “Stirn sehr schmal, vorn gelbbraun, oben vorn mit breitem, braunen rand, aber ohne T-fleck.” [“Forehead very narrow, yellow-brown at the front, with a broad brown border at the top, but without a T-spot.”]. Martin (1911: Plate 5, fig. 5) includes a colour illustration of G. dohrni, but this shows a T-spot on the frons and superior anal appendages different from Krüger’s illustration. Martin (1911) also includes separate illustrations of the anal appendages of dohrni in his Plate 5, reproduced from Martin (1909: fig. 204, and also those of G. dohrni are shown as those of G. basiguttata in fig. 197 in error, see Lieftinck (1934) under G. dohrni), curiously these do agree with Krüger’s illustration. To our knowledge there are no other published illustrations of G. maclachlani whereas the anal appendages of G. dohrni have been illustrated at least twice more: Ris (1911: fig. 11) gives a dorsal view alongside his G. demeter (Ris, 1911) and Lieftinck (1953a: fig. 10 left side images) gives both a dorsal and a lateral view. Gynacantha demeter (not recorded from Sumatra) is very similar to both G. dohrni and G. maclachlani but especially the former, and Dow (2021, note 51) raised doubts over its status as a species separate from G. dohrni but this issue has not been resolved and cannot be resolved here. All three species lack a distinct T-spot on the frons (for G. machlachlani Krüger (1899: 319) only mentions this indirectly: “Von hyalina Selys unterscheidet sie sich durch geringere gröbe, das fehlen des T-flecks” [“It differs from hyalina Selys by its smaller size and the absence of the T-spot”]), easily separating them from G. subinterrupta Rambur, 1842 which has similar anal appendages and whose range overlaps broadly with theirs; this raises severe doubts over the colour illustration purporting to be G. dohrni in Martin (1911); also see below.</p><p>The first author has been able to obtain images of almost the entire type series of both species held in the Krüger collection in Warsaw. This collection contains both males of G. maclachlani listed by Krüger and all of the material listed for G. dohrni with the exception of two males from Sabah. Both of the females of G. dohrni from Sabah (one of which is teneral, with one cercus still attached, the other mature with both cerci broken) are mislabeled as male, this error appears to have originated with Krüger (on labels stating: “L. Krüger determ. 1926”), however this is almost certainly just careless label preparation not reflecting an error in the original paper. More problematically the type series might be composite, the male from Sabah and the mature female from Sabah both appear to have T-spots on the frons (this is based on images of the entire specimen rather than specifically of the head, so not taken from an ideal angle, and the apparent T-spots could be shadows or some other artefact) and if that is the case maybe are not the same species as the specimen from Sumatra, but this might explain Martin’s (1911) illustration. On the other hand, given that the determination labels were added to the type series more than two decades after the description of G. dohrni was published they might have simply been added to the wrong specimens (the incorrect sex on two of these labels might support this hypothesis).Although seemingly not present in Warsaw the other two males from the type series of G. dornhi from Sabah might still be in existence, either mislabeled in the main Krüger collection or in another museum. Of Krüger’s material at least the holotype of Heliaeschna crassa Krüger, 1899 is in the Naturalis Biodiversity Center, Leiden, so the missing G. dohrni specimens could be looked for there. Further to this, Lieftinck (1953a: 258) indicates that in 1938 he had two specimens from the type series of G. dohrni on loan, the male from Sumatra and one specimen from Borneo (referred to as the type and a paratype, but this is incorrect, see below); the male from Sumatra was clearly returned but that from Borneo might not have been.</p><p>Although Krüger (1899) made no explicit type designation in his description of G. dohrni he lists the male from Sumatra (shown in Fig. 20) first and the other material in parentheses, however this seems to indicate nothing more than that the latter specimens were not collected by Dohrn; the description is clearly composite. A label indicating “Type” is present with the male from Sumatra, but it is not clear when this was added, also a label stating that the specimen is G. dohrni determined by L. Krüger in 1926. Nothing that can be considered as a holotype designation is included in Krüger’s description of G. maclachlani but the type specimen from Sabah (Fig. 22) has a handwritten label stating “type” as well as a partly typed, partly handwritten label seemingly added by Lieftinck in 1938 and stating “ HOLOTYPE ” as well as a typed label stating “Type” and label indicating determination by L. Krüger in 1926. We are not aware of any published designation as holo- or lectotype for either species so in fact all the type specimens are syntypes (the first author asked the opinion of Jan van Tol, an authority on the International Code of Zoological Nomenclature on this issue and the latter agreed). There is no need to select a lectotype for G. maclachlani but if the type series of G. dohrni is indeed composite then there are grounds to select a lectotype, in which case the male from Sumatra already labelled as the type would be the obvious and best choice.</p><p>Using the images of the type series of the two species and material from the Kampar Peninsula and Sarawak the following remarks can be made. The length of superior anal appendages (illustrated in dorsal view in Figs 24–26) falls into the same range in both species but the inferior appendage is shorter in G. dohrni compared to G. maclachlani so that the ratio of superior to inferior anal appendage is always greater in G. dohrni than G. maclachlani . Caution must be exercised in quantifying the previous sentence, the exact ratio in any given specimen will vary according to the method used to measure it, e.g. on how the base of the appendages is defined, which can appear different in lateral or dorsal view and in dorsal view can vary according to the exact angle that the specimen is viewed from, and the accuracy of the measurement, for instance an ordinary ruler will clearly give less accurate results than using a microscope lens with a scale. With non-pinned specimens the lateral view is easier to achieve, and the first author takes the measurement of the superior anal appendage from its lowest basal corner to the tip and that of the inferior anal appendage from the same point on the base of the superior anal appendage to the tip of the inferior anal appendage. Note that taking the ratio from measurements made in dorsal view of the same specimens can give a higher value because of the shape of abdominal segment 10. In the specimens from the Kampar Peninsula and Sarawak examined the (lateral) ratio in G. dohrni is consistently greater than 3.6, in one individual (from Sarawak) well in excess of 4, while that in G. maclachlani is consistently below 3.4, and only greater than 3.3 in two out of eight individuals measured. Since the stacked images of the anal appendages of the type material only include dorsal views, ratios for these were calculated (using Photoshop) by measuring the left superior anal appendage (except that shown in Fig. 26 where the left is deformed near the tip, and shorter than the right, in this case the right was used) from its outer lateral base (to be as close as possible to the method used in lateral view) to the level of the apex and the inferior appendage was measured from the a horizontal line at the level of the starting point for the superior anal appendage measurement to the tip; this gives ratios of ca. 3.6 for the syntype of G. dohrni from Sumatra and ca. 3.3 for the two G. maclachlani syntypes.</p><p>Aside from the differences in the ratio of superior to inferior anal appendage length, the superior anal appendages of G. dohrni bear a small but well defined, rounded subbasal interior-ventral expansion, visible in both dorsal and lateral view (and visible even in the illustration in Krüger (1899)). In contrast those of G. maclachlani lack such an expansion, although often a slight thickening is visible in the same position in dorsal view. The superior anal appendages of both species bear many inward directed, hair-like setae on their inner margins, easily visible in dorsal view. In G. dohrni there is an increase in the density and length of these setae starting at less than the length of the inferior anal appendage from the tip of that appendage while in G. maclachlani although there is an increase in density it begins more apically. Note that the illustration in Martin (1909) shows setae rather evenly distributed on the cerci of G. maclachlani, in contrast to the actual condition (compare fig. 205 in Martin (1909) with Figs 25–26 here). The last two differences are the most easily checked characters to differentiate males of the two species, no clear difference in, for instance, body or wing length has been found. There might however be differences in the anal appendages in lateral view but since the first author only requested dorsal views of the anal appendages in the type series of both species it has not yet been possible to check these in the types. In specimens from Sarawak and the Kampar Peninsula identified using the characters mentioned already, the superior anal appendage of G. dohrni viewed laterally is almost completely straight (which is in agreement with Martin’s illustrations of the anal appendages), but that of G. maclachlani is slightly curved over its length (in the same manner as illustrated for G. saltatrix Martin, 1909 by Asahina (1986: 90, fig. 67)); the images of the specimen labelled as ‘type’ of G. maclachlani, which is not pinned, include lateral views of the entire specimen inside a clear plastic envelope, it appears that the condition of the superior anal appendage is the same but certainty is not possible without a high magnification lateral view of the anal appendages (the G. dohrni holotype is pinned and no lateral view at all is currently available). This curved appearance to the cercus in lateral view is not shown in fig. 205 in Martin (1909), but considering there is at least one other problem with Martin’s illustrations of these two species, it cannot necessarily be taken as accurately depicting either of the syntypes of G. maclachlani . There also appears to be a small difference in the apex of the inferior anal appendages viewed laterally but this could not be checked at all in the type material. In the key in Krüger (1899: 19) the length of the pterostigma is used as a distinguishing character for G. dohrni and G. maclachlani, with that of the former stated to be in the range 3.5–4 mm long and that of the latter to be 3mm long. Unfortunately, the pterostigma length does not serve to separate the two species in general, in specimens from Borneo both the length of, and the number of underlying cells to, the pterostigma broadly overlaps.</p><p>Identification of females of both these Gynacantha species remains somewhat problematic. For G. dohrni Krüger (1899) had little to say on the two female syntypes (which might not be conspecific with the male in any case) beyond “Ganz änlich dem ♂. Ein reifes ♀ mit auϐerordentlich dunkel angeräucherten flügeln. Appendices lang und dünn, hinten blattartig erweitert. Letzes Ventralsegment mit 2 Spitzen.” [“Very similar to the ♂. A mature ♀ with exceptionally dark, smoked wings. Appendices long and thin, expanding leaf-like posteriorly. Last ventral segment with two points.”] Latter authors have little or nothing useful to add on the females and that of G. maclachlani has never been described (Martin (1909) includes a short description of the supposed female, but this is based on specimens from New Guinea that are undoubtedly not G. maclachlani), whilst in all cases the females appear to be associated with the males by supposition only. The males of both species have prominent auricles, Martin (1909: 199) describes those of G. dohrni as “énormément grandes” [“enormously large”] and states that “ ♀ comme le mâle, meis le thorax marron, l’abdomen bien moins gonflé à la base, beaucoup moins étranglé au 3”, ...” [“ ♀ like the male, but the thorax brown, the abdomen much less swollen at the base, much less constricted at 3”, ...”] perhaps implying that the female also has large auricles. More concretely, Lieftinck (1953a) clearly implies that what he considered to be female G. dohrni have prominent auricles (unusual in females) when, writing about an atypical female specimen, he states “… the auricles somewhat larger than usual …” The first author of this paper has generally taken the presence of prominent (clearly visible with the unaided eye, as large or almost as large as those of the male) auricles on female Gynacantha from Sundaland that otherwise resemble male G. dohrni as diagnostic for G. dohrni and those listed above were identified on this basis. Female Gynacantha collected by the first author while feeding in numbers with male G. maclachlani (and no other species caught in the same ‘flock’) during rain at a location in southwest Sarawak lack prominent auricles (not easily visible without magnification), so the presence of large, clearly visible without magnification auricles appears to distinguish female G. dohrni from female G. maclachlani but is not guaranteed to be diagnostic for female G. maclachlani .</p><p>In summary, the males of G. dohrni and G. maclachlani can be separated from each other based on the ratio of the superior to the inferior anal appendages, the presence of a small but well defined rounded subbasal expansion on the superior appendages of G. dohrni and differences in the density of setae along the inner margins of the superior appendages.As far as is known females can be separated based on the size of the auricles, with females of G. dohrni having auricles that are larger than usually found in females Gynacantha . At present G. maclachlani is known from Borneo and Sumatra while G. dohrni is known from Peninsular Malaysia, Borneo, Sumatra and Java (Dow et al. 2024) and there is at least one record from Indochina. Given the problemtic identification of these species it is however not unlikely that some published records of G. dohrni are actually of G. maclachlani in whole or part, but such records will need to be individually checked by examination of the specimens concerned. When publishing further records of these two species it is advisable to mention the characters used for identification.</p></div>	https://treatment.plazi.org/id/03DB2A41FFB5FFBBFDBE224D92FFF81F	Public Domain	No known copyright restrictions apply.

A single male Gomphidia was seen perched at the side of a closed canopy PSF stream (Simpang Sianyir, M 1m) during suboptimal weather conditions on 1 x 2023, but flew away before the boat could be brought into a position from which capture was possible. The individual was very darkly coloured, more so than is typical for any species of Gomphidia known from Sundaland. Two species of Gomphidia have been recorded from Sumatra— G. abbotti Williamson, 1907 and G. machlachlani Selys, 1873 (but see below)—both of these species have been recorded in low pH waters elsewhere (e.g. Dow et al. (2012) for G. abbotti and Dow &amp; Reels (2024) for G. machlachlani) but G. abbotti can be ruled out by the coloration of the Simpang Sianyir male. Gomphidia machlachlani is darker than G. abbotti and although still not typically as dark as the Simpang Sianyir male, the first author has collected one male almost as dark as that individual in Sarawak. Moreover, G. machlachlani has been found in numbers in very similar conditions at Maludam National Park in Sarawak (Dow &amp; Reels 2024). Although the Simpang Sianyir male might be G. machlachlani, Lieftinck (1954) questioned the identity of Sumatran material supposedly of that species. Specimens will need to be collected before identification to species can be made.</p><p>Whichever species of Gomphidia is present in the Kampar Peninsula, the genus has not been recorded in Riau Province until now.</p></div>	https://treatment.plazi.org/id/03DB2A41FF8FFFBCFD2C25699760FB98	Public Domain	No known copyright restrictions apply.

It has also sometimes been found at streams in oil palm or at the oil palm—forest boundary. In the Kampar Peninsula it has so far only been found at two tributary streams of the Serkap River. In February 2023 in sunny conditions in the afternoon single males were found perched in small clearings on Sungai Sianyir, but in overcast conditions in October 2023 no individuals definitely of this species were seen at the same stream. Also in October 2023, but in sunny conditions, males were relatively common on Simpang Kanan, although the species had not been found there in February 2023.</p></div>	https://treatment.plazi.org/id/03DB2A41FF8CFFBFFDCD232A9772F9AA	Public Domain	No known copyright restrictions apply.

Common on open parts of the streams and rivers in the main part of the Kampar Peninsula, as it often is in low pH waters. Quite abundant on the large pond at location P5d in September 2023 but not even seen there in June 2023.</p></div>	https://treatment.plazi.org/id/03DB2A41FF81FFB2FDCF25C5973CF9E2	Public Domain	No known copyright restrictions apply.

M4b: 1 ♀ (RER23 _ LIB162; RER), 13 vi 2023 .</p><p>Remarks. Although four species of Lyriothemis have been recorded in Sumatra ( L. biappendiculata (Selys, 1878), L. cleis Brauer, 1868, L. magnificata (Selys, 1878) and L. salva Ris, 1927), none had been recorded in Riau Province until now. The single female collected is certainly not L. biappendiculata, is atypically coloured for L. cleis and is probably L. magnificata . We are not aware of any previous records of this genus definitely from PSF but, for instance, there is an old female specimen of L. magnificata from the Matang Road in Sarawak in the collection of the Sarawak Museum (Dow &amp; Morris 2021), much of the surrounds of the Matang Road near to Kuching was originally PSF; there are also records of L. cleis from the surrounds of Tasik Bera (Norma-Rashid et al. 2001) and Tasik Chini (Kalkman 2004) in Pahang that could be from PSF. The female from the Kampar Peninsula was collected whilst it was flying around in a small clearing made by a treefall ( L. cleis is quite often found in such situations in other types of forest).</p></div>	https://treatment.plazi.org/id/03DB2A41FF87FFB4FD2825EB975AFB6A	Public Domain	No known copyright restrictions apply.

One individual was collected and another seen in the same stand of freshwater mangrove beside the Kampar River where M. megabinluyog was found. Although described from South Sumatra the only later Sumatran records had been from Belitung (Alfarisyi 2018, 2019). Although fairly widely distributed in Sundaland, this species has not often been recorded but might well be more common than is currently obvious. It appears to prefer mangrove and nipa palm habitats that are difficult to work in and is often found at the banks of rivers or around creeks with deep water in these habitats, so that a boat is required to find it.</p></div>	https://treatment.plazi.org/id/03DB2A41FF9BFFABFDA3219196EDFEA4	Public Domain	No known copyright restrictions apply.

This is the taxon listed as P. serrata A in, for instance, Dow (2021). Until recently it was not possible to tell which of three similar taxa was the true P. serrata . At least in the lowlands this is a PSF species while the true P. serrata appears to be primarily a species of freshwater swamp forest. The first author is working on a revision of Pornothemis and it would be premature to make further comments here.</p></div>	https://treatment.plazi.org/id/03DB2A41FF9BFFA8FDC5232795D2F989	Public Domain	No known copyright restrictions apply.
