Pseudocypretta sangpradubae sp. nov. is easilyrecognized by the morphology of valves and soft parts. Primarily, its valve surface is sculptured by stronger pits and plenty of long setae, which make it different from other Pseudocypretta species. Unlike P. amor and P. franki, P. sangpradubae sp. nov. possesses a CR (absent in the former two species) and its aspect is different from that of P. maculata . The CR distally bears a long flagellum-like seta in P. maculata, whereas it ends with a triangular blade-like tip in P. sangpradubae sp. nov.</p></div>	https://treatment.plazi.org/id/03E187D6FFEC7A22FF59FB03FB1AFE7A	Public Domain	No known copyright restrictions apply.

Cyprettadopsis hanjavanitae sp. nov. is obviously discriminated from C. sutura, the type species, by the Cp shape in lateral and dorsal views, which is less elongated subtriangular and more ovate, respectively, in the new species. Relying solely on the external morphology of the Cp, especially the presence of the needlepoint-like pores along the outer lists of the valves, C. hanjavanitae sp. nov. is similar to C. kalasinensis sp. nov. The differences can be seen in the Cp size, in which C. hanjavanitae sp. nov. is larger, and in the valve sculpture that is somewhat smooth with weak shallow pits at the middle in C. hanjavanitae sp. nov. (strong pits throughout the Cp in C. kalasinensis sp. nov.). In addition, the soft parts features are clearly different, such as the length of the shortest seta on A1 terminal segment and of the longest seta on the A2 exopodite (both setae being longer in C. hanjavanitae sp. nov.), the slenderer α seta on the Md palp, the longer d2 seta on the T2 and the longer e and f setae on the T3.</p></div>	https://treatment.plazi.org/id/03E187D6FFE77A24FF59FB8CFA50FC62	Public Domain	No known copyright restrictions apply.

The aspects of marginal septa among the three genera of Cyprettadopsini were presented by Savatenalinton (2025). However, as three more new species (two in Cyprettadopsis and one in Pseudocypretta) are herein described, the aspects of marginal septa are reconsidered; the marginal septa in Pseudocypretta can be variable in the LV on both anterior and posterior margins, whereas in the RV they are stable with complete septa on both anterior and posterior margins. In Cyprettadopsis, the septa variability (either incomplete or complete septa) occurs in the anterior margins of both valves while the posterior ones only possess complete septa. These suggested that the presence of marginal septa in these two genera would occur via different modes. Mixtadopsis has incomplete septa on the LV and complete septa on the RV, and thus far no interspecific variation of marginal septa is known. It should be noted that the postero-ventral septa on the LV have pointed tips in Cyprettadopsis and Mixtadopsis, which differ from Pseudocypretta . It should also be mentioned that the incomplete marginal septa recognized in the tribe Cyprettadopsini, have not yet been found in Cypretta (subfamily Cyprettinae). The existence of marginal septa in three lineages ( Cyprettinae, Cypridopsinae, Herpetocypridinae —see, e.g., Kong et al. 2014; Savatenalinton et al. 2022) could represent a convergent evolution in the Cyprididae .</p><p>The dorsal subapical seta on the basal segment of the Mx1 palp is a significant diagnostic feature within Cyprettadopsini .It is present in Pseudocypretta and Mixtadopsis but absent in Cyprettadopsis (see also Savatenalinton 2025). The discovery of the two new Cyprettadopsis species supports this character of the genus.</p><p>The pseudosegmentation on the A2 natatory setae was first reported in M. namiotkoi (see Savatenalinton 2025). In the present study, all three new species possess such structure of the A2. Additionally, reinvestigations were done in specimens of Thai P. maculata and C. sutura (Fig. 15C) to confirm the taxonomic status. Consequently, apart from M. namiotkoi, this feature is also seen in all species of Cyprettadopsis, and some species of Pseudocypretta ( P. maculata and P. sangpradubae sp. nov.). Hence, it presently appears in all three genera of Cyprettadopsini .</p><p>The g seta on the T3 is recognized in all three new species described here. The reexamination in other members of the tribe uncovered that it exists in at least three species of Pseudocypretta ( P. maculata, P. lineata and P. sangpradubae sp. nov.) and all Cyprettadopsis species but missing in Mixtadopsis . It can be regarded as a generic character at least in Cyprettadopsis and Mixtadopsis . Nonetheless, this feature should be used with caution as it is a small seta and can be easily overlooked.</p><p>In the present work, valve surfaces of all representatives of the three Cyprettadopsini genera were also examined based on literature and specimens (when possible). The results revealed that all species have two types of seta: 1) seta without thick base and 2) seta with thick base (Fig. 1F). The former type has a smooth seta appearing in all Cyprettadopsini species, except for P. sangpradubae sp. nov., in which the seta displays a serrated margin (Figs 1E–F). Additionally, type 1 seta can be very short, thin and scantily distributed (Figs 15A–B), as in the case of three Pseudocypretta ( P. maculata, P. lineata, P. amor), which can easily be overlooked. It can be long with a dense arrangement, as occurs in P. sangpradubae sp. nov., or long with sparse distribution as seen in the five remaining species of the Cyprettadopsini . Nearly all species of the tribe have long type 2 seta, except for three Pseudocypretta species ( P. maculata, P. lineata, P. amor), where it appears short and very thin. The arrangement of type 2 seta is scattered in all members of Cyprettadopsini, but more densely in P. sangpradubae sp. nov. In M. namiotkoi, this seta type is seen with difficulty because they are located in pits (see Fig. 1B in Savatenalinton 2025). Apart from Cyprettadopsini, type 2 seta is also seen in Songkhramodopsis (Tribe Songkhramodopsini) and Thaicypridopsis (Tribe Zonocypridini) (see Savatenalinton 2018, 2023). It should be noted that in the Cyprididae, type 2 seta has so far been recognized only from the Cypridopsinae . In all Pseudocypretta members (except P. franki —see discussion below) and the two new Cyprettadopsis species, the pore of the type 2 seta is also accompanied with a small tubercle situated on the border (Figs 1E–F). Similar lateral tubercles of pores, which were called microreliefs, were recognized in Candona perforata Alekseeva &amp; Krivorotkin, 2025, a species in the Candonidae (Alekseeva et al. 2025) . This resemblance between Cyprettadopsini species and C. perforata could be a convergent aspect, as they belong to different lineages. Nonetheless, in C. perforata, pores are rimmed and accompanying setae lack the thick bases, differing from the situation in Cyprettadopsini .</p><p>The valve surface of P. franki is exceptional as it is apparently different from other Pseudocypretta, but more similar to that of Cyprettadopsis and Mixtadopsis . Its taxonomic position as a member of Pseudocypretta is questionable and it most likely belongs to Mixtadopsis (see discussion below). In other Pseudocypretta, the valve surface is grounded by shallow pits, with stronger expression in P. sangpradubae sp. nov. All Cyprettadopsis species have smooth or weakly pitted surfaces, and pores along the outer lists of both valves, whereas Mixtadopsis displays the most complex ornamentation in the tribe, with strong pits, longitudinal ridges/grooves on the ventral side, and concentric sculpture as well as pores along the outer lists of both valves.</p><p>Except for P. franki, dark dots on the valve surface were found in all Pseudocypretta with different aspects. Pseudocypretta maculata has three dark dots per valve and a transverse band on each valve in dorsal view (Fig. 16A). Pseudocypretta amor shows a similar pattern with P. maculata, but the transverse band comprises a heart-shaped dark patch (see Fig. 2 in Ferreira et al. 2022). Although the color pattern of P. lineata was not mentioned/illustrated in the description, a list of different features between P. lineata and P. maculata was provided in which no color pattern on the valve surface was included. Thus, it is assumed that P. lineata has a similar pattern with P. maculata . In P. sangpradubae sp. nov., the number of dark dots per valve is four and the transverse bands on the Cp in dorsal view are weakly developed (Fig. 16B). Unlike Pseudocypretta, dark dots and transverse bands on the valve surface are absent in all Cyprettadopsis species, but unshaped, dark patches were seen instead (Fig. 16C). In Mixtadopsis, only transverse dark bands were recognized on the Cp in dorsal view (Fig. 16D). Such pigmentation on the valve surface is possibly considered a typical character. For example, the dark dots define the genus Pseudocypretta as they appear in all species.</p><p>Like in most Cypridopsinae members in Thailand, all three new species are parthenogenetic as no males have been found in the populations. Thus far, a bi-sex population in Thai Cypridopsinae has been reported only in Songkhramodopsis meischi Savatenalinton, 2023 in the Lower Songkhram River Basin (see Savatenalinton 2023).</p><p>Pseudocypretta sangpradubae sp. nov. is the second Pseudocypretta described from Southeast Asia, after P. maculata (see Klie 1932), and the first one from Thailand. The present discovery of the two new Cyprettadopsis species not only provides additional strong characters but also confirms its distinct genus. Herein, the updated distinguishing features and a key to genera of the Cyprettadopsini are provided. Thus far, nine genera and 15 species of Cypridopsinae have been recorded in Thailand. This indicates the high diversity at the tribe level as they belong to six (of a total of seven) tribes, including a Thai endemic, Songkhramodopsini (Savatenalinton 2023) .</p><p>Key to genera of the tribe Cyprettadopsini</p><p>1.

It can be distinguished by the color pattern on the valve surface (see discussion above) and the soft parts morphology, especially the CR (absent in P. amor). Pseudocypretta lineata also closely resembles P. maculata . Apart from the different chaetotaxy of the limbs, a small difference in the external morphology is the straight-line sculpture on the ventral side of the Cp, which is absent in P. maculata . These phenomena suggest that the three species form a closely related group and thus it could affect the identifications of the previously recorded P. maculata in several regions (e.g. Battish 1978, 1982; Victor &amp; Fernando 1979, 1981). Hence, further investigations of such P. maculata specimens are needed to confirm identifications.</p><p>The taxonomic position of P. franki is somewhat doubtful as its morphology differs from other Pseudocypretta . Firstly, it lacks the dark dots on the valve surfaces that occur in all other Pseudocypretta members. The presence of needlepoint-like pores along the outer lists of valves also makes it different from Pseudocypretta, but similar to Cyprettadopsis and Mixtadopsis . The valve sculpture of P. franki is (weakly) concentric, which is a character of Mixtadopsis . Additionally, a groove on the anterior part of the RV, which is an indicative character of Mixtadopsis, is also seen in P. franki, but in an incomplete form, appearing only in the mouth area (a complete groove in M. namiotkoi). Pseudocypretta franki and M. namiotkoi also possess the similar pattern of marginal septa (complete septa on the RV, incomplete septa on the LV). The existence of a dorsal subapical seta on the basal segment of the Mx1 palp, mentioned in the description of P. franki (but not drawn), supports the similarity of P. franki with Mixtadopsis rather than Cyprettadopsis, as the seta is present in Mixtadopsis but absent in all Cyprettadopsis . Based on such aspects, P. franki is herein allocated to Mixtadopsis . Although this allocation alters the character state of the CR (present in M. namiotkoi, absent in Mixtadopsis franki (Ferreira et al., 2023) nov. comb.), it is not unusual in the Cyprettadopsini, as a similar situation also exists in Pseudocypretta . This illustrates that, in these genera, the occurrence of the CR is a specific character. In addition, from this combination, some features of Mixtadopsis are no longer generic characters, e.g. the morphologies of the exopodite and aesthetasc Y on the A2, and the flat postero-ventral morphospace of the LV. The discovery of more species could provide a better understand in this account.</p></div>	https://treatment.plazi.org/id/03E187D6FFF67A32FF59FAACFA58FE06	Public Domain	No known copyright restrictions apply.

Apart from the distinct modes of septa occurrences, the significant differences also include the absence of dark dots on the valve surfaces and of the dorsal subapical seta on the basal segment of the Mx1 palp (both features present in Pseudocypretta —see Ma &amp; Yu 2020; Savatenalinton et al. 2022; Ferreira et al. 2022), and the cylindrical base of the CR (triangular base in Pesudocypretta). The h2 claw on the T2 is also shorter and less curved in Cyprettadopsis .</p><p>The two new species are assigned to Cyprettadopsis as features of the valves and soft parts are identical to the original diagnosis of the genus (Savatenalinton 2020). Cyprettadopsis currently contains three species, and these allow consideration of the proper generic characters, which is a limitation in monospecific genera. Apart from the anterior marginal septa of both valves, other generic characters in the diagnosis of Cyprettadopsis are confirmed. Although the complete anterior septa of both valves in C. hanjavanitae sp. nov. are not congruent to the diagnosis, this aspect would be an interspecific variability within the genus, like the case of Pseudocypretta (see discussion above). Additionally, the segmentation of the A2 aesthetasc Y is also different, which is four in the two new Cyprettadopsis species, but three in C. sutura and, thus, serves as a specific character in Cyprettadopsis . It should be mentioned that several additional features existing in all species of Cyprettadopsis could be considered generic characters, namely the presence of needlepoint-like pores along the outer lists of valves, the pseudosegmentation of the A2 natatory setae, the g seta on the T3, the large β seta on the Md palp, and the absence of dark dots on the valve surfaces and of the dorsal subapical seta on the basal segment of the Mx1 palp.</p><p>Considering that Cyprettadopsis hanjavanitae sp. nov. and C. kalasinensis sp. nov. exhibit only minor differences in carapace morphology (e.g., shape and surface sculpture; see remarks on C. hanjavanitae sp. nov.), with most differences occurring in the soft parts, this could indicate the presence of a species complex within Cyprettadopsis, similar to that reported for the closely related genus Pseudocypretta .</p><p>Distribution</p><p>The genus Cyprettadopsis is apparently restricted to Thailand, while Pseudocypretta has a wider recorded distribution from Asia, South America and Africa. However, the occurrence of African Pseudocypretta ( P. franki) is doubtful as its morphology is more similar to Mixtadopsis than to Pseudocypretta (see discussion above). Certainly, there are at least two lineages of Pseudocypretta: Oriental and Neotropic. Pseudocypretta maculata is a common species in Thailand as it was reported from a wide range of habitats in several parts of the country (e.g. Savatenalinton &amp; Suttajit 2016). Pseudocypretta sangpradubae sp. nov. has a more restricted distribution (Fig. 5). It inhabited four localities, from a total of 30 surveyed wetlands in the middle part of the Chi River Basin. The two new Cyprettadopsis species appear to have a limited known distribution, as they have only been recorded from their respective type localities to date, whereas C. sutura is more widely distributed across several localities in the middle part of the Chi River Basin.</p><p>Morphological evolution</p><p>It has been long known that the A2 is a limb related to locomotion and its setae produce the thrust for swimming, especially the natatory setae. In Cyprettadopsini, the lateral margins of the A2 natatory setae are discontinuously thickened which make them look like segments. The possible reasons for such exceptional features include that 1) it is a morphological adaptation to the environment occurring via natural selection and 2) it is a feature occurring via natural mutation. During movement, the natatory setae extend outward from the limb, which results in a larger surface area (Hunt et al. 2007). Thus, the thickening margins of the natatory setae could reinforce the strength of the setae, which perhaps promotes better locomotion, such as a longer period of swimming or a faster movement. This could explain that the setae thickening is an adaptive feature in the evolutionary pathway and thus supports the first possibility. Hunt et al. (2007) studied the swimming behaviour of Cypridopsis vidua (O.F. Müller, 1776) belonging to the same subfamily as the Cyprettadopsini, and found that the swimming is evenly continuous without rapid acceleration. Thus, the faster movement (if it is the case) most likely occurs by the increasing number of stroke cycles. Given the fact that C. vidua which lacks the thickening in the A2 natatory setae, swims by moving the A2 with the rate of 15 complete strokes per second (Hunt et al. 2007), the rate in the Cyprettadopsini members would therefore be higher. This capability could be elucidated by the behavioural observations in the tribe.</p><p>Smith et al. (2023) outlined the hypothesis on the strongly serrated claw G2 of the A2, which co-occurs in the tribes Zonocypridini, Plesiocypridopsini (existing in Sarscypridopsis) and Cyprettadopsini . They proposed that it could be a morphological adaptation in egg laying. Thus, based on the morphology of this claw, Cypridopsinae has so far been composed of two groups (with and without well-developed serration), and this could suggest the different behaviour of egg placement within the subfamily. Additionally, it also implies the independently evolved feature in their own lineages (tribes).</p></div>	https://treatment.plazi.org/id/03E187D6FFF77A31FF59FE39FDEFFD7E	Public Domain	No known copyright restrictions apply.
