3D3887A08766C040FCBA8353FCC898B2.taxon	materials_examined	Type species: Megadiestramima intermedia Storozhenko et Gorochov, 1992, by original designation. Note. This genus includes large representatives of Diestramimini having the following diagnostic characters (see also the generic key in Gorochov & Storozhenko, 2015): in male, the posteromedian process of seventh abdominal tergite is more or less short (almost truncate or spine-like) and covering only the proximal part of paraprocts from above (Figs 1, 6, 11, 15, 21, 25, 29, 34, 58, 62, 66, 75); in female, this process is smaller or almost undeveloped, usually widely rounded but sometimes tubercle-like or with a very small apical notch; each male paraproct is rather high, plate-like, having a large rounded dorsal (dorsoproximal) lobe and narrower ventroapical process or hook (Figs 2, 7, 12, 16, 22, 26, 30, 35, 59, 63, 67, 72, 76); in female, each paraproct less high, roundly triangular, and with a small apical tubercle; the male genitalia have a few dorsal sclerites (one larger Y-shaped sclerite and a pair of smaller ribbon-like sclerites; Figs 36 – 48) or only rudiments of such sclerites (Fig. 49), but in some species, these genitalia lack sclerites (Figs 51 – 57); female genital plate is rath- er diverse in shape (Figs 4, 5, 9, 10, 14, 18 – 20, 23, 24, 27, 28, 32, 33, 61, 65, 70, 73, 77, 78); ovipositor is long, narrow, barely curved upwards, acute at the apex, and lacking distinct drilling teeth or tubercles (Fig. 50).	en	Gorochov, A.

3D3887A08762C040FF1D82B2FAA49B92.taxon	description	(Figs 1 – 5, 36 – 38) Material examined. Northern Vietnam: 5 males (holotype and paratypes), 3 females (paratypes), Quang Ninh Prov., Bai Tu Long Bay, Fong Vong I., forest, 11 – 12. X. 1990, V. Kuznetsov (ZIN, holotype and 1 female; EATB, 4 males, 2 females); 2 males (paratypes), same province and bay, Thanh Lam I., forest, 18. X. 1990, V. Kuznetsov (EATB); 5 females, same province, “ Bai Tu Long I. and National Park ”, X. 2008, S. Ryabov, N. Orlov (ZIN). Note. This species is sufficiently described by Gorochov & Storozhenko (1992). Here it is recorded from a new point nearest to its type locality, but all the specimens from this point are females somewhat darker than the type specimens, and thus, these determinations are not very exact. Moreover, the genital plates of these females are similar in shape but not identical: some of them have a pair of small lateral spinules in the distal half (approximately as in Figs 9, 10, 14), but others are without such spinules (Figs 4, 5); sometimes, there is a spinule on one lateral edge of this plate only (almost as in Fig. 18). These differences may be individual variability. The paratype of this taxon from southern part of China is a nymph, and its belonging to this species is very problematic.	en	Gorochov, A.

Structure of body typical of this genus, however: head with rostral tubercles rather narrow (their base laterally as wide as distance between each rostral tubercle and nearest eye); apical segment of maxillary palpus almost equal to half of fore femur in length; right coxa with short spine, but left one with very short spine; hind femur with nine inner ventral non-articulated spinules and a pair of small apical denticles; armament formula of tibiae and of hind basitarsus characteristic [dea, v ~ 2, v 2, v 3 a / d 2 a, v ~ 2, v 2, v 3 a / d 30 e- 27 i (d 30 e- 28 i), d 2 sa, 6 a / d 1 c, dac]; inner dorsal spur of hind tibia barely protruding beyond apex of dac [= unpaired (central) dorsoapical spur of hind basitarsus]; sixth abdominal tergite with very short posteromedi- an lobe; posteromedian process of seventh abdominal tergite moderately short, i. e. similar to that of M. (M.) intermedia but less wide (its width in distal part approximately two mm, but this width in M. intermedia about 3.5 mm; for comparison see Figs 1 and 6); paraproct with moderately long ventroapical process (space from cercal base to apex of paraproct about 1.8 times as long as this process; in M. intermedia, this process longer, and this ratio almost equal to two) and small but distinct convexity between base of this process and widely rounded dorsal lobe (in M. intermedia, this convexity indistinct; see Figs 2 and 7); genitalia with median sclerite well developed and distinctly Y-shaped, with distal (unpaired) part of this sclerite slightly longer than a pair of its proximal parts (i. e. this distal part slightly shorter than in M. intermedia), and with membranous lobes larger than in this species (see Figs 37 and 39). Variations. Colouration of second male with longer darkened apical portion of femora and more distinct (almost brown) spots on rest part of fore and middle femora; this male also with short (identical) spines on both coxae; armament of legs very weakly variable. Female. Colouration and structure of body similar to those of holotype, but size somewhat larger, coloration barely darker but with brown apical part of each femur and dorsal surface of proximal half of middle and hind femora as well as poorly distinct darkish spots and areas on rest parts of legs, armament of legs in limits of variability in males but with slightly more numerous non-articulated dorsal spinules on hind tibia, sixth abdominal tergite almost without posteromedian lobe, seventh abdominal tergite with very short and rounded posteromedian lobe, paraproct smaller and roundly triangular as well as with small ventroapical tubercle. Genital plate indistinguishable from that of female of M. (M.) intermedia in shape, with small but distinct lateral denticles (non-articulated lateral spinules) locat- ed in distal half of this plate (Figs 9, 10); ovipositor as in Fig. 50. Length in mm. Body: male 17.5 – 23, female 24; pronotum: male 6.5 – 8, female 8.4; fore femur: male 13.7 – 17.5, female 16.7; hind femur: male 28 – 35, female 33; hind tibia: male 33 – 41, female 39; hind basitarsus: male 5.5 – 7, female 6.5; ovipositor 19. Comparison. The new species is most similar to M. (M.) intermedia in the structure of male abdominal apex (including median sclerite of male genitalia) and may be only a subspecies of the latter species. Differences of M. borealis from all the other congeners are given above, in the key and description. Etymology. This species name is the Latin word “ borealis ” (northern), because it is given the species described from the most northern localities of Megadiestramima s. l.	en	Gorochov, A. V., Storozhenko, S.

Comparison. The new species is most similar to M. (M.) extensa in the structure of male genitalia. It also may be only a subspecies of the latter species, and its differences from all the other congeners are given in the key above. Etymology. This species is named after A. V. Abramov, a well-known researcher of Vietnamese mammals who collected these interesting insects.	en	Gorochov, A. V., Storozhenko, S. Yu.

XI. 2008, V. Bezborodov (ZIN, 2 females; EATB, 1 male, 1 female). Note. The species was described from a single male (Gorochov, 1998) in details. Later, Storozhenko (2009) on the base of the above-mentioned material described previously unknown females of this species. These females are very similar to each other, but their genital plates are somewhat different: in one female, the lateral edges of this plate are not convex in the middle part and with distinct lateral spinules in the proximal half (Figs 19, 20); in other females, these lateral edges are clearly convex in the middle part and with lateral spinules in the distal half (but one of the latter females is without right lateral spinule on this plate; Fig. 18). These differences show either strong variability in this character, or the belonging of these females to different sympatric species.	en	Gorochov, A. V., Storozhenko, S. Yu.

Orlov (ZIN). Description. Male (holotype). General appearance similar to that of all previous congeners. Colouration light brown with almost dark brown large areas under eyes (reaching lateral parts of clypeus) and small areas on dorsomedial parts of rostral tubercles, brown areas behind eyes, most part of tergites, apical parts of femora, hind tibia, paraproct, epiproct and genital plate, as well as intermediate in colour (between brown and light brown) rest of head dorsum, ventrolateral areas on metanotum and on seven anterior abdominal tergites, more posterior tergites, cerci, fore and middle legs, hind tarsus and dorsal surface of hind femur. Rostral tubercles rather thick (their base laterally almost 1.5 time as wide as distance between each rostral tubercle and nearest eye); apical segment of maxillary palpus somewhat shorter than half of fore femur (this femur approximately 2.2 times as long as this segment); both fore coxae with very short spine; hind femur with 8 – 9 inner ventral non-articulated spinules; armament formula of tibiae and hind tarsus characteristic [dea, v 2, v 2, v 3 a / d 2 a, v ~ 2 (ve), v 2 (vi), v 3 a / d 32 e- 30 i (d 33 e- 29 i), d 2 sa, 6 a / d 1 c, dac]; inner dorsal spur of right hind tibia distinctly protruding beyond apex of dac (in left leg, such spur much shorter, possibly restored); sixth abdominal tergite without distinct posteromedian lobe but with very small posteromedian notch; seventh abdominal tergite with very short posteromedian process (shorter than in all previous congeners; Figs 34, 35); paraproct with dorsal lobe not projected backwards, with ventroapical process moderately long, strong, straight and having more or less rounded (nort acute) apex, and with slight convexity between these lobe and process (Fig. 35); genitalia with a pair of narrow sclerotized ribbons (rudiments or traces of partly reduced Y-shaped median sclerite; Fig. 49). Female unknown. Length in mm. Body 25; pronotum 9.2; fore femur 18; hind femur 36; hind tibia 39; hind basitarsus 7.3. Comparison. The new species is most characteristic among Megadiestramima s. str., because its seventh abdominal tergite in male has a shortest posteromedian process, its male paraproct is with straight ventroapical process having the apex not acute, and its male genitalia are with rudiments or traces of Y-shaped median sclerite (see also the key above). Etymology. This species name is the Latin word “ centralis ” (central), because the new species was collected in the central part of Vietnam.	en	Gorochov, A. V., Storozhenko, S. Yu.

Colouration light brown with four pairs of brown spots on head (large area under eye reaching lateral part of clypeus, oblique stripe on gena under eye, spot behind eye, and slight stripe along dorsal edge of eye) and one brown median spot under rostral tubercles, a pair of small darkish marks located near each other along anterior edge of pronotum, a pair of similar marks but widely separated from each other along posterior edges of six anterior tergites (more posterior tergites almost uniform), brown apical parts of all femora, and reddish brown antennal flagellum. Lateral ocelli more or less intermediate in size between those of M. (N.) o. orlovi and M. (N.) o. lata (Fig. 79); hind femur with ten inner ventral denticles and a pair of apical ones; armament formula of tibiae and hind basitarsus similar to that of previous species of Neodiestramima [d 2 a, v 2, v ~ 2, v 3 a / d 2 a (dia), v ~ 2, v ~ 2, v 3 a / d 126 e- 123 i (d 122 e- 125 i), d 2 sa, 6 a / d 1 c (d 0 c), dac]; inner dorsal spur of hind tibia slightly not reaching apex of dac; sixth abdominal tergite without posteromedian lobe; seventh abdominal tergite with short spine-like posteromedian process which looking as small angular projection (such process in M. orlovi almost twice as long as this process; for comparison see Figs 66, 69, 71 and 75); paraproct long (almost as in M. o. orlovi in length) but slightly narrower and with apical spinule direct- ed more backwards (paraproct approximately 3.5 times as long as posteromedian process of seventh abdominal tergite; Fig. 76); genitalia with somewhat longer lateral membranous lobes and slightly shorter dorsomedian lobe (Fig. 57). Variations. Colouration sometimes without distinct marks on tergites or with darkish spots on dorsal surface of hind femur. Armament of legs and size of lateral ocelli slightly variable: some specimens with these ocelli intermediate in size between those pictured in Figs 74 and 79. Female. Colouration and structure of body as in males. However: one female with more numerous darkened marks along posterior edges of tergites, darker (almost greyish brown) spots on dorsal surface of hind femur and sparse darkish marks on light parts of legs; all females with abdominal apex almost as in M. (N.) orlovi, but apex of spine-like process of their seventh abdominal tergite narrowly rounded, angular or slightly notched, as well as genital plate with apical part clearly narrower and from barely notched (practically truncate; Figs 77, 78) to distinctly rounded [in female from Lam Dong Prov. (nearest to Dong Nai Prov.), this plate with somewhat wider apex (almost as in Fig. 70), but its lateral edges convex as in Fig. 78]. Comparison. This species differs from the nearest one in the posteromedian process of seventh abdominal tergite of male clearly shorter (see also the key above). Etymology. The species name consists of the Latin words “ brevis ” (short) and “ spina ” (spine), because male of this species has the posteromedian process (spine) of seventh abdominal tergite short.	en	Gorochov, A.

This genus is characterized by the following features: body is medium-sized; seventh abdominal tergite of male has a pair of posterodorsal spines or angular projections (Figs 80, 82, 84, 86); this tergite in female has a pair of posterodorsal tubercles significantly shorter than these spines; paraproct is elongate (stick-like or bifurcate; Figs 81, 83, 85, 87) in male and usual (but having apical tubercle) in female; male genitalia are completely membranous and having six lobes (Figs 117, 146); ovipositor is normal but having its apical part weakly denticulated.

3D3887A08777C054FF128370FCCB9A76.taxon	materials_examined	Type species: Diestrammena palpata Rehn, 1906, by original designation. Note. The genus was considered in the first communication of this article where the key to its species and subspecies was also published (Gorochov & Storozhenko, 2015). Later, two additional papers with descriptions of new representatives of this genus appeared (Qin et al., 2016; Zhu & Shi, 2018). From the both genera previously discussed in this communication (Megadiestramima and Mimadiestra), Diestramima differs in the presence of only posteromedian process of seventh abdominal tergite in male which is significantly longer, completely covering paraprocts and their processes (vs. there are a pair of posterior spines or projections on this tergite, or the above-mentioned posteromedian process is distinctly shorter than paraprocts and almost not covering them or covering the paraproctal bases only; for comparison see Figs 1, 2, 6, 7, 11, 12, 15, 16, 21, 22, 25, 26, 29, 30, 34, 35, 58, 59, 62, 63, 66, 67, 72, 75, 76, 80 – 83 and 88, 89, 94), as well as in the male genitalia having additional lateral membranous lobes distinct also in proto- and deutonymphs (Figs 98 – 103) [probably, it is a unique character for imago of this genus (compare with Figs 111 – 120), but in Megadiestramima, protonymphs may be with similar additional lobes (Figs 104, 105) which are partly or strongly reduced in older nymphs (Figs 106, 107, 109, 110) and indistinct in imago (Fig. 108)]. Here, the genus Diestramima is divided into three subgenera which are in partial accordance to the first and second groups of this genus established by Gorochov (1998): Diestramima s. str.; Baculitettix subgen. nov.; Excisotettix subgen. nov. However, some species of this genus described by Gorochov & Storozhenko (2015), Qin et al. (2016), Zhu & Shi (2018) and listed in OSF are here not includ- ed in any subgenera, because these species are in need of an additional study.

Paratypes. Two females, same data as for holotype (ZIN). Description. Male (holotype). General appearance similar to that of nominotypical subspecies (Gorochov & Storozhenko, 2015), but body somewhat larger. Colouration greyish brown with almost light greyish brown head having dark brown dorsum and a few darkish marks on rest part (a pair of vertical stripes on epicranium under antennal cavities, two vertical stripes on each gena under eye, lateral areas on clypeus), greyish brown tergites having almost dark brown dorsal part of pronotum and light brown lateral parts of all tergites as well as a few small dark brown marks along posterior edges of these tergites (except for pronotum), and rest of body light greyish brown but with following marks: apical portions of all femora dark brown; hind femur additionally with greyish brown dorsolateral longitudinal area, located on second third of this femur, and with small darkish marks along its ventral outer keel; proximal half of tibia slightly darkened in fore and middle legs but dorsally spotted in hind leg (i. e. with darkened marks between spines); spines of hind tibia also darkened; apex of posteromedian process of seventh abdominal tergite with small light dorsomedian triangle. Rostral tubercles well developed, rather large, with rounded apices and very narrow, deep and long fissure between them; lateral ocelli moderately large (almost intermediate between those pictured in Figs 68 and 79); hind femur with 15 – 16 ventral inner spinules (except for a pair of small apical denticles); armament of tibiae and tarsi distinguished from that of holotype of D. (B.) p. propria Gorochov et Storozhenko, 2015 mainly by six dorsal denticles on hind basitarsus; abdominal apex (including genitalia) very similar to that of nominotypical subspecies, but posteromedian process of seventh abdominal tergite with somewhat widened apical part having lateral lobules directed more aside (in nominotypical subspecies, this apical part practically not widened, and these lobules directed downwards; for comparison see Figs 88, 90 and 91, 92). Female. Colouration and structure of body similar to those of male, but mandibles with lateral darkenings, tergites and legs also slightly dark- er (with pterothorax and anterior half of abdomen dorsally almost dark brown, and with legs having somewhat more numerous darkish spots), armament of legs insignificantly varied, seventh abdominal tergite with angular posteromedian tubercle, and paraproct rather simple (i. e. not large, almost triangular and with apical tubercle). Genital plate elongately triangular, with rather narrow apex having small (but not shallow) rounded notch and convex lateral edges of most part of this plate (its basal part with rather small lateral lobules separated from main body of this plate by folds; Fig. 93); ovipositor more or less as in Megadiestramima s. l. but rather long (hind femur approximately 1.5 times as long as ovipositor). Length in mm. Body: male 32, female 32 – 34; pronotum: male 9.5, female 9.5 – 10; fore femur: male 22, female 21 – 23; hind femur: male 38, female 39 – 42; hind tibia: male 42, female 43 – 45; hind basitarsus: male 7.5, female 7.5 – 8; ovipositor 25 – 27. Comparison. The new subspecies differs from D. (B.) p. propria mainly in the characters of seventh abdominal tergite of male listed above (in its description). The both subspecies of this species are known from only their type localities situated in different provinces of Northern Laos: Luong Nam Tha and Xieng Khouang. These provinces are located rather far from each other.	en	Gorochov, A. V., Storozhenko, S. Yu.

3D3887A08776C057FCBA84BAFA529A37.taxon	materials_examined	Type species: Diestramima multa Gorochov, 1994, by original designation. Note. This genus was also considered in the first communication of this article with the key to its species and subspecies (Gorochov & Storozhenko, 2015). From all the other genera of Diestramimini, Adiestramima differs in the following unique character: its male genitalia have six membranous lobes (as in the other genera of Diestramimini, except for Diestramima s. l. and some nymphs of Megadiestramima s. l.), but their ventrolateral lobes are very long (much longer than the other lobes; Fig. 120). The latter character is also distinct in old nymphs of this genus (Figs 118, 119). There are some additional characters allowing us to give more or less clear generic determination for females of Adiestramima: the rostral tubercles are usually more acute (angular) than in related genera and directed almost forwards (not forwards / downwards); pronotum has the dorsal edge almost straight or slightly concave in profile; female paraproct has spine-like to tubercle-like apical process (projection). The shape of paraprocts and of posteromedian process of seventh abdominal tergite in male is rather diverse and allow us to divide this genus into three subgenera: Adiestramima s. str.; Hamatotettix subgen. nov.; Ulterotettix subgen. nov. (see key to subgenera below).	en	Gorochov, A. V., Storozhenko, S. Yu. (2019): New and little-known taxa of the tribe Diestramimini (Orthoptera: Rhaphidophoridae: Aemodogryllinae) from Southeast Asia.

Description. Male (holotype). Body moderately small for this genus. Colouration light brown (almost yellowish) with four brown longitudinal bands on head dorsum (medial bands reaching rostral apices; lateral bands fused with more or less darkened lateral areas behind eyes, but these areas separated from eyes by yellowish stripe along posterior edge of each eye), four somewhat lighter (brownish grey) vertical stripes under eyes and antennal cavities (latter stripes reaching lateral parts of clypeus), reddish brown proximal part of antennal flagellum and small dorsal spot on scape, darkish (barely visible) areas on lateral parts of six anterior tergites, and brown to brownish grey spots on fore and middle femora, tibiae and tarsi (hind legs missing). Rostral tubercles moderately short, directed mainly forwards and with almost angular apices; lateral ocellus large, its length slightly greater than distance between it and rostral apex; pronotum with dorsal edge slightly concave in anterior half and slightly convex in posterior half; armament formula of fore and middle tibiae characteristic [d 2 a, v 2, v 2, v 3 a / d 2 a, (v 2), v 2, v 3 a]; abdominal tergites simple, but seventh one with moderately long and not narrow posteromedian process having subapical narrowing, a pair of apical lobules (these lobules almost spine-like but with rounded apices) and one ventrosubapical semiglobular inflation (Figs 95 – 97); paraproct short, with short and strong hook directed upwards, and with ventrolateral (posterolateral) keel-like ridge running from this hook to almost base of cercus (Fig 96, 97); genitalia with dorsomedian lobe moderately large (long) and having large dorsal inflation and a pair of small apical lobules, with ventromedian lobe wide and short but somewhat concave posteriorly and having posteromedian fork-like lobule, with a pair of short dorsolateral lobes, and with a pair of very large ventrolateral lobes which clearly longer than all other lobes (Figs 120, 121). Female unknown. Length in mm. Body 14.5; pronotum 4; fore femur 13.2. Comparison. The new species is distinguished from similar A. (A.) multa and A. (A.) proxima by the posteromedian process of seventh abdominal tergite of male somewhat narrower before its apical part and with the apical lobules thinner, this process also with a semiglobular subapical inflation on the ventral surface, and male paraproct distinctly lower and with the apical hook acute. From A. (H.?) bicolor and A. (U.?) citrea with unknown males, the new species differs in the body significantly smaller or in the colouration distinctly less variegate, respectively. Etymology. This species name is the Latin word “ originalis ” (original), because this species has a peculiar structure of the male abdominal apex.	en	Gorochov, A. V., Storozhenko, S. Yu.

3D3887A08774C051FCBA8573FB4A9F17.taxon	description	(Figs 122 – 131, 147 – 149) Holotype. Male, Southern China, Yunnan Prov., Ailaoshan Mountain Range, W of Shuitangzhen Town, “ 24 08 31 N / 101 23 52 E ”, 2555 m, 4. VI. 2011, I. Belousov, I. Kabak, N. Korolev (ZIN). Paratypes. One male, 2 females, same data as for holotype (ZIN); 1 male, same province, but SSE of Shuangjiang Town, “ 23 25 01 N / 99 57 01 E ” and “ 23 25 10 N / 99 57 24 E ”, 2425 – 2570 m, 20. VI. 2011, I. Belousov, I. Kabak, N. Korolev (ZIN). Description. Male (holotype). Body typical of Tamdaotettix s. str. but rather small. Colouration moderately spotted: head light brown with six brown spots on dorsum (lateral spots occupying also upper parts of lateral surfaces of head behind eyes); thoracic tergites brown with light brown lower parts, characteristic yellowish dots and stripes along lateral edges of dorsum and several yellowish dots between them; thoracic pleurites, legs and abdominal tergites almost uniformly light greyish brown but with distal two thirds of hind femur and processes of sixth and seventh abdominal tergites darker (almost brown), with poorly distinct darkish or lightish spots on distal parts of all femora and on fore and middle tibiae, and with barely distinct small darkish marks on tergites; other parts of body (including cerci, paraprocts and genital plate) almost yellowish. Body distinctly horseshoe-shaped in profile; head with rostral tubercles finger-like, contacting with each other from bases to apices, and directed more downwards than forwards; thoracic tergites shiny (except for their lower parts), but all abdominal tergites matt (not shiny); pronotum with convex dorsal edge in profile; femora practically unarmed, i. e. with apical spurs on fore and middle legs typical of Aemodogryllinae, and with one very small inner apical denticle on hind femur only; armament of tibiae and hind basitarsus characteristic [dea, v 2, v ~ 2, v 3 a (v 2 a) / d 2 a, ve, v 2, v 3 a / d 56 e- 58 i (d 59 e- 63 i), d 2 sa, 6 a / d 1 c, dac]; dorsal inner spur of hind tibia reaching apex of dac; sixth and seventh abdominal tergites with rather long posteromedian processes (first of these processes thin, spine-like and with a pair of angular denticles at apex; second of them significantly wider, with apex V-shaped (reversed) from behind and having three pairs of very small denticles, and somewhat protruding beyond apex of previous process; Figs 122 – 124); paraproctal processes finger-like, moderately short and arcuately curved aside (Figs 122, 123); genitalia with membranous lobes rather long (except for ventromedian one), and with dorsomedian lobe having oval apical part (Fig. 147). Variations. Other male from same locality with only insignificant differences in armament of legs and in shape of processes of sixth and seventh abdominal tergites (Figs 125, 126); apparent differences in shape of paraproctal processes probably only result of movability of paraprocts (see Figs 122 and 126). However, male from another locality distinguished by slightly longer process of seventh abdominal tergite having a pair of distinct apical denticles only, by narrower apex of process of sixth abdominal tergite, and by somewhat less arcuate shape of paraproctal processes (Figs 127 – 129); but it similar to holotype in shape of male genital lobes (Figs 148, 149). Female. General appearance as in males, but processes of sixth and seventh abdominal tergites clearly shorter and not spine-like (Fig. 130), and paraprocts simple (without processes); genital plate widely rounded in distal part (Fig. 131); ovipositor moderately long and thin, with distal part in profile gradually narrowing to narrowly acute apex, and without distinct denticles. Length in mm. Body: male 12 – 14, female 12 – 13; pronotum: male 4 – 4.8, female 4.2 – 4.4; fore femur: male 6 – 6.5, female 5.8 – 6; hind femur: male 13.8 – 15.5, female 13.6 – 14; hind tibia: male 14 – 16, female 13.8 – 14.2; hind basitarsus: male 2.7 – 2.9, female 2.5 – 2.7; ovipositor 8.5 – 9. Comparison. The new species is most similar to T. (T.) dilutus Gor. in the shape of male abdominal apex, but its body is significantly smaller and with only thoracic tergites shiny (in T. dilutus, four anterior tergites shiny), process of sixth abdominal tergite in male has a pair of apical denticles (no such denticles in T. dilutus; Figs 133, 135), process of seventh abdominal tergite in male is with the apex more V-shaped (less transverse) from behind (see Figs 124 and 134) and having paired (from two to six) apical denticles (vs. having three apical denticles; Figs 134, 136), and male genitalia are with oval apex of dorsomedian lobe (vs. with narrowly angular apex of this lobe; Figs 115, 116). Etymology. The new species is named after the Ailaoshan Mountain Range.	en	Gorochov, A. V., Storozhenko, S. Yu.

3D3887A08773C050FCAB85EEFA659AAD.taxon	description	(Figs 142 – 145, 150, 151) Holotype. Male, Northern Vietnam, Cao Bang Prov., Phia Oac – Phia Den National Park, eastern slope of Phia Oac Mt, 40 km W of Cao Bang Town, 22 ° 36 ' 27 '' N, 105 ° 52 ' 00 '' E, 1600 – 1800 m, 22. V – 6. VI. 2018, L. Anisyutkin, A. Abramov (ZIN). Paratypes. One male, 11 nymphs (4 males, 7 females), same data as for holotype (ZIN). Description. Male (holotype). Body similar to that of T. (T.) ailaoshanicus but with following differences: colouration darker, greyish brown with dark brown tergites (four anterior tergites with lower parts greyish brown, and with yellowish marks on dorsum almost as in thoracic tergites of T. ailaoshanicus), almost dark brown two thirds of hind femur, and light brown tarsi and venter of body (except for brown genital plate) as well as spots on fore and middle femora and on all tibiae; rostral tubercles with more angular apices; four anterior tergites shiny, but two posterior ones with matt lower parts; hind femur with 5 – 6 ventral inner spinules and with apical denticle as in T. (T.) ailaoshanicus; armament of tibiae and hind basitarsus characteristic [dea, v 2, v 2, v 3 a / d 2 a, ve, v ~ 2, v 3 a / d 53 e- 50 i (d 49 e- 54 i), d 2 sa, 6 a / d 5 c (d 6 c), dac]; sixth abdominal tergite with posteromedian process very long (somewhat protruding beyond apex of posteromedian process of seventh abdominal tergite), distally spine-like, lacking a pair of apical denticles, and with widening in proximal half (Figs 142, 143); seventh abdominal tergite with rather long and moderately wide posteromedian process having characteristic apex (this apex with one small median denticle and a pair of rounded ventral lobules as well as with rather high and almost semiglobular inflation located above this denticle; Figs 142 – 144); paraproctal process short, strongly and angularly curved upwards at base (Fig. 143); genitalia with dorsomedian lobe having also oval apical part which somewhat more separated from rest of this lobe (Figs 150, 151). Variations. Second male with armament of legs and shape of tergal processes and paraprocts insignificantly different (Fig. 145). Nymphs. Nymphs similar to imago in general appearance, but body slightly smaller, processes of tergites and paraprocts in male nymphs slightly shorter (process of sixth abdominal tergite reaching apex of process of seventh abdominal tergite but not projected behind it), these processes almost undeveloped in female nymphs, male genitalia with more or less angular apex of dorsomedian lobe, and female genital plate shorter than in adult female of T. (T.) ailaoshanicus and with widely truncate distal part. Length in mm (male). Body 10.5 – 12; pronotum 4.5 – 5.1; fore femur 6.7 – 7.2; hind femur 14 – 15.5; hind tibia 15.2 – 17; hind basitarsus 3 – 3.4. Comparison. The new species is most similar to T. (T.) pullus Gor. in the structure of male abdominal apex (especially in the shape and length of process of sixth abdominal tergite) (see Figs 137, 139 – 141 and 142, 143, 145), but it differs from the latter species in the body much smaller, apex of process of seventh abdominal tergite in male higher (less transverse) from behind (see Figs 138 and 144), male paraproct with shorter and strongly curved process (this process almost straight in T. pullus; see Figs 141 and 143, 145), and dorsomedian lobe of imaginal male genitalia with rounded (not angular) apex. Etymology. The new species name consists of the Latin prefix “ mini- ” (small) and species name T. pullus, because the new species is very similar to the latter congener but having much smaller body.	en	Gorochov, A.
