When described in 2014, Maotoweta virescens was believed to be one of New Zealand’s rarest cave wētā (Rhaphidophoridae). Here, we present new information about the distribution, ecology, and life history of the species. M. virescens has now been recorded from indigenous forest sites throughout the length of the western South Island, where it can occur in relatively high abundance. M. virescens shows a close association with arboreal mosses, particularly Weymouthia mollis, roosting within them during the day and feeding on them at night. The wētā has also been documented feeding on lichens and dead insects. The species is hypothesized to have a lifecycle of approximately one year, closely linked to season. Eggs are thought to hatch out relatively quickly after being laid in summer and early autumn, with the species overwintering as nymphs and maturing the following late spring through to early-autumn. Further work is required to fully understand its biology. A comparison was made between active night searching and vegetation beating as two different methods for the detection and monitoring of M. virescens. Beating of W. mollis and other suitable M. virescens microhabitats was found to be significantly more effective than night searching. Our results show that M. virescens is widespread and can occur at relatively high densities within South Island temperate forests, with the species’ perceived rarity to date largely owing to a lack of survey effort and the past use of ineffective sampling methods.

In this study, we identify and describe a new species of the subgenus Tachycines (Tachycines), namely Tachycines (Tachycines) nigrocorporis sp. nov., which was collected from Guizhou Province, China, bringing the species number of this subgenus to twenty-two. The morphological differentiation between this new species and other species of Tachycines (Tachycines) is discussed. The morphological photographs of the new species are provided.

Barcode libraries are generally assembled with two main objectives in mind: specimen identification and species discovery/delimitation. In this study, the standard COI barcode region was sequenced from 681 specimens belonging to katydids (Tettigoniidae), cave crickets (Rhaphidophoridae), and leaf-rolling crickets (Gryllacrididae) from Zhejiang Province, China. Of these, four COI-5P sequences were excluded from subsequent analyses because they were likely NUMTs (nuclear mitochondrial pseudogenes). The final dataset consisted of 677 barcode sequences representing 90 putative species-level taxa. Automated cluster delineation using the Barcode of Life Data System (BOLD) revealed 118 BINs (Barcodes Index Numbers). Among these 90 species-level taxa, 68 corresponded with morphospecies, while the remaining 22 were identified based on reverse taxonomy using BIN assignment. Thirteen of these morphospecies were represented by a single barcode (so-called singletons), and each of 19 morphospecies were split into more than one BIN. The consensus delimitation scheme yielded 55 Molecular Operational Taxonomic Units (MOTUs). Only four morphospecies (Imax > DNN) failed to be recovered as monophyletic clades (i.e., Elimaea terminalis, Phyllomimus klapperichi, Sinochlora szechwanensis and Xizicus howardi), so it is speculated that these may be species complexes. Therefore, the diversity of katydids, cave crickets, and leaf-rolling crickets in Zhejiang Province is probably slightly higher than what current taxonomy would suggest.

Previously, only two species of Hercostomus Loew were known to occur in Inner Mongolia. Here two species from Inner Mongolia are described as new to science, namely Hercostomus chifengensissp. nov. and Hercostomus triangulatussp. nov. Three new records of Hercostomus in Inner Mongolia are added. A key to the species of Hercostomus in Inner Mongolia is provided.

Comparison. The new species is distinguished from other representatives of this genus by its large-sized body, except for E. ampla, E. bona and E. nataliae which are similar in size. Nevertheless, E. apicoexcisa can be distinguished from E. ampla by the posteromedian process of the ninth abdominal tergite of male directed backwards and with almost straight lateral margins (Figs 1D, E), whereas the latter species (E. ampla) has this process strongly curved downwards and with slightly concave lateral margins (in dorsal view); E. bona has this process slightly bent downwards, rounded in its distal part, and less narrowed in the middle part than in the new species; and E. nataliae has this process bent upwards and with trilobate apical part. Additional differences of the new species from all Thailand congeners are given in a key below. Male of this new species can be additionally distinguished from those of E. angusta by the posteromedian process of the ninth abdominal tergite not separated from the basal part of this tergite with help of a transversal fold, by the apex of this process broadly rounded and with a small but rather deep notch in dorsal view, and by the epiproct more or less triangular and with long apical process that curved forward; whereas male of the latter species have this process separated from the basal part of the ninth abdominal tergite by a pair of folds, the apex of this process almost truncate (i.e. without any notch in dorsal view), and the epiproct almost rectangular with a distinctly shorter apical process. Female of the new species also can be distinguished from that of E. angusta by the abdomen with a shortly rounded posteromedian projection on both the eighth and ninth abdominal tergites and with subgenital plate shortly triangular; whereas female of the latter species has these abdominal tergites without any distinct projection posteriorly, and its subgenital plate more elongate. This species can be also distinguished from E. visibilis by the apex of the posteromedian process of the ninth abdominal tergite of male broadly rounded and with a small but rather deep notch in dorsal view, and by the male epiproct more or less triangular and with a long apical process curved forward; whereas male of the latter species has this process distinctly truncated posteriorly and without any apical notch in dorsal view, and the epiproct almost rectangular but with a shortly blunted apical process. Female of this new species can be also distinguished from that of E. visibilis by the abdomen with shortly rounded posteromedian projections on the eighth and ninth abdominal tergites and with a shortly triangular subgenital plate; whereas the female abdomen of the latter species is with angular posteromedian projections on the eighth and ninth abdominal tergites and with a more elongate subgenital plate. And from all other congeners (E. curvata, E. fossa, E. laosi, E. orlovi, E. rotundata, E. t. tarasovi and E. truncata), the new species may be additionally distinguished by the following features: E. fossa and E. laosi have this process shorter, more widened, and without any notch at the apex in dorsal view; E. curvata and E. orlovi have this process more curved downwards and with more concave lateral margins; E. t. tarasovi has this process distinctly narrower; E. rotundata has this process more rounded (semi-oval); E. truncata has this process distinctly shorter and trapezoidal in the shape. Also, the female of some of these species lacks projections on the eighth and ninth abdominal tergites (E. laosi, E. t. tarasovi) or has a projection only on the ninth abdominal tergite (E. orlovi). Etymology The new species name is combined from the two Latin words: apico- (a prefix means “apex” or “apical part”) and excisus (a word means “excise” or “cut off”) referring to the posteromedian process of the male ninth tergite having a small excision (notch) at the apex., Published as part of Dawwrueng, Pattarawich, Gorochov, Andrei V., Pinkaew, Nantasak & Vitheepradit, Akekawat, 2023, Review of the genus Eurhaphidophora Gorochov, 1999 (Orthoptera: Ensifera Rhaphidophoridae) from Thailand, with description of a new species, pp. 351-362 in Zootaxa 5278 (2) on pages 353-354, DOI: 10.11646/zootaxa.5278.2.7, http://zenodo.org/record/7906263

Distribution: South China Note: Lu et al. (2022) gave the comparison of this Chinese species with E. ampla and E. orlovi from Vietnam. Herein, we compare this species with E. pawangkhananti that is greatly similar to it. Nevertheless, these two species can be separated based on their abdominal structures. Male of E. curvata has the posteromedian process of the ninth abdominal tergite not separated from this tergite, the epiproct widely rounded at the apex and without apical lobes, and the posterior margin of the subgenital plate between its styles convex; whereas male of E. pawangkhananti has the posteromedian process of the ninth abdominal tergite separated from this tergite by a transverse fold (Fig. 5G), the posterior epiproctal margin with a narrow apical process, and the posterior margin of the subgenital plate between its styli almost straight. Also, E. orlovi differs from very similar E. pawangkhananti and E. curvata in the lateral margins of the male ninth tergite proccess clearly arcuate (but in the first two species, these margins are more straight); E. pawangkhananti differs from E. orlovi and E. curvata also in a more angular apical part, in contrast with this part straight (truncate) or almost straight in the two latter species; E. curvata differs from E. orlovi and E. pawangkhananti in a widely rounded apical part of the male epiproct, whereas this epiproct has a specialized apical part in the both latter species (slightly bilobate apex and narrow apical process, respectively). Female of E. curvata is still undiscovered, therefore its comparison with other females of this genus cannot be provided., Published as part of Dawwrueng, Pattarawich, Gorochov, Andrei V., Pinkaew, Nantasak & Vitheepradit, Akekawat, 2023, Review of the genus Eurhaphidophora Gorochov, 1999 (Orthoptera: Ensifera Rhaphidophoridae) from Thailand, with description of a new species, pp. 351-362 in Zootaxa 5278 (2) on page 358, DOI: 10.11646/zootaxa.5278.2.7, http://zenodo.org/record/7906263, {"references":["Lu, X., Huang, X. & Bian, X.

Thai rhaphidophorid species of the genus Eurhaphidophora Gorochov 1999 are reviewed. Previously, two species and one subspecies (E. bispina Gorochov 2010; E. pawangkhananti Dawwrueng, Gorochov & Suwannapoom 2020; E. tarasovi doitungensis Dawwrueng, Gorochov & Suwannapoom 2020) were reported from Thailand. In this study, a new additional species (E. apicoexcisa sp. nov.) from Ratchaburi Province is described. Males of this new large-sized species are easily recognized from other males of Eurhaphidophora by an almost straight and lamellar posteromedian process of the ninth abdominal tergite, the presence of a small but rather deep and rounded apical excision on this process, and a long apical part of the epiproct. Females of the new species also can be distinguished from other Thailand congeners by the presence of a small rounded posteromedian projection on the both eighth and ninth abdominal tergites, and a shortly triangular subgenital plate. An updated species catalogue of all known species and taxonomic keys to Thailand Eurhaphidophora species for males and females are provided.

Eurhaphidophora curvata Lu, Huang & Bian, 2022 Zootaxa, 5093(3), 392. http://lsid.speciesfile.org/urn:lsid: Orthoptera.speciesfile.org:TaxonName:517710 Type specimen: China, Yunnan Province, Gengma, Banmai. Distribution: South China Note: Lu et al. (2022) gave the comparison of this Chinese species with E. ampla and E. orlovi from Vietnam. Herein, we compare this species with E. pawangkhananti that is greatly similar to it. Nevertheless, these two species can be separated based on their abdominal structures. Male of E. curvata has the posteromedian process of the ninth abdominal tergite not separated from this tergite, the epiproct widely rounded at the apex and without apical lobes, and the posterior margin of the subgenital plate between its styles convex; whereas male of E. pawangkhananti has the posteromedian process of the ninth abdominal tergite separated from this tergite by a transverse fold (Fig. 5G), the posterior epiproctal margin with a narrow apical process, and the posterior margin of the subgenital plate between its styli almost straight. Also, E. orlovi differs from very similar E. pawangkhananti and E. curvata in the lateral margins of the male ninth tergite proccess clearly arcuate (but in the first two species, these margins are more straight); E. pawangkhananti differs from E. orlovi and E. curvata also in a more angular apical part, in contrast with this part straight (truncate) or almost straight in the two latter species; E. curvata differs from E. orlovi and E. pawangkhananti in a widely rounded apical part of the male epiproct, whereas this epiproct has a specialized apical part in the both latter species (slightly bilobate apex and narrow apical process, respectively). Female of E. curvata is still undiscovered, therefore its comparison with other females of this genus cannot be provided.

Ten new karst cave-dwelling rhaphidophorids species of the subgenus Gymnaeta of the genus Tachycines are described from Guizhou Province, southern China; i.e., Tachycines (Gymnaeta) zhongisp. nov., Tachycines (Gymnaeta) jinniuisp. nov., Tachycines (Gymnaeta) shibenzhangisp. nov., Tachycines (Gymnaeta) lahaidensissp. nov., Tachycines (Gymnaeta) pinglangussp. nov., Tachycines (Gymnaeta) shanduensissp. nov., Tachycines (Gymnaeta) buyiisp. nov., Tachycines (Gymnaeta) portaesp. nov., Tachycines (Gymnaeta) ziyunensissp.nov., and Tachycines (Gymnaeta) jialiangensissp. nov. All specimens were collected from Guizhou Plateau.

An annotated list of 42 species in 26 genera and four families of Orthoptera recorded from Beringia (Northeast Yakutia, Chukotka, Magadan region, and Kamchatka in Russia, Alaska in USA, Yukon and the Northwestern Territories in Canada) is given. The distribution of species is clarified. The exchange of orthopteran faunas between Asia and America by the Bering Land Bridge in Pleistocene was strongly limited. The only three species, Tetrix subulata (Linnaeus, 1761), Melanoplus frigidus (Boheman, 1846), and Stethophyma grossum (Linnaeus, 1758), are recorded from both Asian and American parts. The orthopteran fauna of Beringia is not original. Majority of Beringian species are widespread throughout either Asia or North America. There are only four endemic grasshoppers, namely two Asian subspesies, Melanoplus frigidus kamtchatkae (Sjosted, 1935) and Aeropedellus variegatus gelidus Mistshenko, 1951, and two American species, A. arcticus Hebard, 1935 and Bruneria yukonensis Vickery, 1969. Composition of the regional faunas is briefly discussed. The monotypic genus Bohemanella Ramme, 1951 is again considered as a synonym of Melanoplus Stål, 1873, where a type species of the former genus, Melanoplus frigidus (Boheman, 1846) comb. resurr., forming its own species group.

Tachycines asynamorous “Greenhouse camel cricket” Figures 65 (lateral), 66 (dorsal, ventral) Plates 41 (lateral), 42 (dorsal, ventral) A single camel cricket, Tachycines asynamorous, was scanned, but substantial fluid infilling of tracheae resulted in assessing homology of many branches difficult. Although of suboptimal quality, this specimen was included because of its placement within Orthoptera and the relative modifications of the mesothoracic tracheae, specifically how they relate to modifications for sound reception. Identifiable tracheae are labeled and described here but should be considered preliminary. Our mesothorax assessments differ from Ander (1939), particularly with H-DCT and H-VCT. Ander identifies most of the larger tracheae extending into head as multiple branches of H-VCT and the small branch as H-DCT, whereas we have determined the small dorsal branch is T 2-VB, the next ventral branch is H-DCT, followed by H-VCT, which does have a split into H-VCT and a smaller anterior trachea that has T 1- AL ventrad. DESCRIPTION: HEAD: T 1- DLT partially visible and likely extending into head capsule. H-DCT and H-VCT both thick, with dorsal-ventral connection likely but not visible. Several air spaces visible, likely preservational artifacts. H-VCT splits into two branches, large dorsal one and smaller ventral, which proceeds anteriorly with T 1- AL ventrad. THORAX: T 2- S with five branches: T 2-DB, T 2-VB, H-DCT, H-VCT, and T 1- PL. T 2-DB running dorsad and anteriad, extending into head capsule after broad curve along prothorax. H-DCT thick, extending anteriad through prothorax into head capsule. H-VCT splitting into two branches: large dorsal trachea, extending anteriad into head, and a smaller ventral branch, extending anteriad into head with T 1- AL ventrad. T 2-VC not visible but likely present; many ventral thoracic tracheae infilled with fluid. T 2-DB runs dorsad, with T 2- AL branching in hairpinlike turn ventrad into T 2- L. Remaining branches of T 2-DB not visible. T 2-VB partial, with T-shaped intersection with T 2- VLT. H-DCT and H-VCT both large, of similar size, extending into head as described above. T 1- PL running directly ventrad, partial, likely joining with T 1- AL but not visible in this scan. T 3- S branches largely infilled and difficult to differentiate, appearing to include: T 3-DB, T 3-VB, T 3-lvl, T 2- PL, and T 3-suf. T 3-DB partial, with T 3- AWL visible, leading to T 3- AL, dorsad before curving sharply ventrad and posteriorly into hind leg. T 3-VB running ventrad, joining with T 3- VLT. T 3-lvl extending mediad, joining with T 3- VLT, with small branch posteriad connecting with T 3- PL. T 3-suf partial, extending mediad and slightly anteriorly. T 3-VL possibly visible on specimen left side; T 3-VL likely present but infilled. ABDOMEN: A 1..8- S present. A 1- S modified from subsequent abdominal segments, with large ventral T 3- PL branch. A n -VB visible on most segments, leading to partially infilled A n - VLT. A n -DB likely present but infilled and not visible. A n - DLT likewise probably present but not visible, likely infilled.

Dolichopoda apollinea Di Russo and Rampini sp. nov. (Figure 8) Type material Holotype J: Calabria, Pollino Massif, Cassano allo Ionio, Sant ̍ Angelo cave complex, 260 m asl., 14 December 2021, Di Russo and Rampini leg. (MZUR). Other material examined Same locality, date and collector as the holotype: 4J, 3♀, 1 nymph. Calabria, Pollino Massif, Cerchiara Calabra, Serra del Gufo cave, 15.06.2019 F. Larocca leg. 2 nymphs; Pollino Massif, S. Lorenzo Bellizzi, Conoide cave, 04.07.2019 F. Larocca leg. 1J; Pollino Massif, Francavilla Marittima, Caprio cave, 20.10.2019 F. Larocca leg. 1♀, 2 nymphs. Type locality The Sant̍ Angelo cave complex is a group of 16 more or less developed caves located at the base of the karst hill named ′il muraglione̍. Two of these, situated at 260 m asl, are more than 1000 m long (Larocca 2003). Etymology The name of the new taxon refers to the ancient appellation of the Pollino Massif as Apollo Mountain. Diagnosis The new taxon is different from the other Calabrian species in the smaller size of the males, the more squared lobes of the tenth tergum that are strongly haired, and the median process of the epiphallus characterised by a prominent carina extending from the base for more than half its length. On the contrary, the females appear quite similar to D. palpata and D. calabra in the shape of the subgenital plate and the denticulation of the inner valvae of the ovipositor. Description Male. Relatively small in size; not uniform in body colour, thorax and abdomen brownish dorsally while paler ventrally. Legs long, uniformly yellowish, with the posterior edge darker. Femora unarmed. Fore tibia armed with 5–6 spines on sides of the lower edge, 3/5 spines on the upper edge. Mid tibia with 5/7 short spines on both sides of the upper edge and 3/4 spines on the lower edge. The hind tibia is longer, with 19/21 spines of varying length on both sides of the upper edge and 3 homogeneous spines on the lower external edge. Tenth tergum with two almost squared lateral lobes, strongly haired (Figure 9 (a)). The lobes are separated by a large median depression holding two pronounced conical tubercles. The subgenital plate is globular and deeply incised in the middle; lateral lobes are triangular with two prominent cylindrical styli (Figures 9 (b,c)). The median process of the epiphallus is almost slender, with a triangular basis. In the middle, a prominent carina occurs from the basis to almost the second half of the total length. In lateral view it is uniformly curved. Narrow basal process with the anterior lobes more developed than the posterior ones (Figures 9 (d,e)). Plica dorsalis membrane semicircular in shape. Length (mm): body 15.00; pronotum 4.00; fore femur 15.00; mid femur 15.00; hind femur 24.00; fore tibia 17.00; mid tibia 18.00; hind tibia 30.00; hind tarsus 11.00; 1st article of hind tarsus 6.00. Female. Relatively larger than male (16–24 mm). Sternites VII, VIII and IX are well developed, showing a prominent posterior edge. Subgenital plate sclerotised, globular and semicircular (Figure 9 (f)). Ovipositor uniformly curved (12 mm) with the apex of the external valvae strongly acuminated and curved upward. The inferior valvae, with the base almost round, have 17–20 denticles (Figure 9 (g))., Published as part of Di Russo, Claudio, Allegrucci, Giuliana & Rampini, Mauro, 2023, Molecular and morphological analyses disclose the existence of three species of Dolichopoda (Orthoptera: Rhaphidophoridae) in the Calabria region (Italy), pp. 372-394 in Journal of Natural History 57 (5 - 8) on pages 382-387, DOI: 10.1080/00222933.2023.2186277, http://zenodo.org/record/7799738, {"references":["Larocca F. 2003 Grotte e voragini dal Monte Pollino alla Catena Costiera Larocca F (ed.).

Legs long and slender. Fore femur about 1.2 times longer than the pronotum, ventrally unarmed, internal genicular lobe with 1 small spine, external genicular lobe with 1 long spine; fore tibia ventrally with 2 inner spines and 2 outer spines, apex with 1 small outer spine on dorsal surface and 1 pair of long spines on ventral surface, between the paired ventral spines with 1 small spine. Middle femur ventrally unarmed, internal and external genicular lobes with 1 long spine respectively; middle tibia ventrally with 2 inner spines and 1 outer spine, apex with 1 pair of dorsal small spines and 1 pair of ventral long spines, between the paired ventral spines with 1 small spine. Hind femur ventrally with 1 inner spine and without outer spine; hind tibia dorsally with 54 inner spines and 47 outer spines, arrange in groups, ventral and dorsal surface with a pair of small subapical spines respectively, apex with 1 pair of long dorsal spines and 1 pair of long ventral spines; the longest dorso-apical spine obviously exceeding the dorsoapical spine of hind metatarsus (Fig. 1F). Hind metatarsus keeled beneath. Epiproct like the shape of tongue (Fig. 1G). Paraproct distinctly longer than the epiproct (Figs. 1G, H). Apexes of the paired dorsolateral lobes of male genitalia distinctly sclerotized; median lobe with distinct lateral sclerites; epiphallus of male genitalia small and indistinct (Figs. 2A, B). Female. General appearance similar to that of male (Figs. 3A–D), but hind femur ventrally with 3 inner spines. Ovipositor about half the length of hind femur; base of ovipositor slightly broad, narrowing to apex; apex pointed and slightly curved upwards; almost indistinct denticles on ventral edge of distal part of inferior valves (Fig. 3E).

The species Pseudotachycines guizhouensis is rather similar to Pseudotachycines procerus, but can be distinguished from the latter by several morphological characters. First, the shape of the sclerotized part of the dorsal lateral lobe of male genitalia is different between P. guizhouensis and P. procerus. Second, the female subgenital plate of P. guizhouensis is triangular, but in P. procerus, the female subgenital plate is quadrangular. Third, the number of the inner spines on the hind femur of P. guizhouensis is lower than that in P. procerus.

First, the shape of the sclerotized part of the dorsal lateral lobe of male genitalia is different between P. guizhouensis and P. procerus. Second, the female subgenital plate of P. guizhouensis is triangular, but in P. procerus, the female subgenital plate is quadrangular. Third, the number of the inner spines on the hind femur of P. guizhouensis is lower than that in P. procerus., Published as part of Huang, Shihui, Lin, Chun & Luo, Changqing, 2023, New taxonomic status of the Pseudotachycines procerus guizhouensis Zhu & Shi 2022 (Rhaphidophoridae: Aemodogryllinae: Aemodogryllini), pp. 496-500 in Zootaxa 5230 (4) on pages 497-498, DOI: 10.11646/zootaxa.5230.4.7, http://zenodo.org/record/7564185, {"references":["Zhu, Q.

Platystethynium (Platypatasson) earlyi Huber, sp. n. (Hymenoptera: Mymaridae), is described from both sexes reared from an egg of Rhaphidophoridae (Orthoptera) found in an old mining tunnel in New Zealand. The male is micropterous and has lateral ocelli but no median ocellus, a unique feature in Mymaridae found so far only in males of Platystethynium Ogloblin species. The remaining described Eastern Hemisphere species of Platystethynium are discussed and Platystethynium glabrum Jin & Li, syn. n., is placed in synonymy under P. onomarchicidum Ogloblin. A key to females, and males where known, of the described Eastern Hemisphere species of Platystethynium is given.

The genera Gymnaetoides and Pseudotachycines are endemic to China and are morphologically homogeneous. The few available diagnostic characters make species identification particularly challenging. Species cannot be classified according to the given generic diagnosis, and phylogenetic analyses have not been reported. Here, we reconstruct the phylogeny using Bayesian inference and maximum likelihood and employ four approaches to delimit species. The results suggest that both Gymnaetoides and Pseudotachycines are paraphyletic. Therefore, we revise their taxonomy based on the combination of morphological characters and molecular data. A new genus Homotachycines Zhu & Shi gen. nov. is erected, and six new combinations are proposed. Species delimitation identifies 15 new species and one new subspecies: Gymnaetoides huangshanensis, G. petalus, G. yangmingensis, G. lushanensis, Pseudotachycines procerus, P. procerus guizhouensis, P. zhengi, P. nephrus, P. sagittus, P. fengyangshanensis, Homotachycines triangulus, H. quadratus, H. baokangensis, H. fusus, H. concavus, and H. qinlingensis sp. nov. Moreover, we find that the shapes of the dorsal lateral lobes and the dorsal median lobe of the male genitalia are also important characters for identifying these genera and that the shapes of the dorsal and lateral sclerites of the male genitalia are suitable for the classifications of species.

Zhu et al. (2022) proposed the genus Megatachycines based on the description of a new species and the reviewed genus Microtachycines.

This new species is similar to Megatachycines elongatus, and the morphological differentiation between the two species is discussed. Morphological information including diagnosis of the new species, description of male genitalia, and some related photographs of males and females are provided.

We record Dolichopoda lustriae Rampini & Di Russo, 2008 (Orthoptera: Ensifera: Rhaphidophoridae) from the Pindus mountain range in Epirus, Greece, more than 200 km to the north of the type locality in Aetolia-Acarnania. We show that this species has an unusually broad distribution for a Balkan cave cricket, and can also live independently of caves, instead inhabiting the crevices of large rock formations. We found D. lustriae to be sympatric with Troglophilus zorae Karaman & Pavićević, 2011, whose presence in Greece is recorded for the first time in this study. We provide high-quality photographs of the habitus and genitalia of D. lustriae and re-describe its morphology. Detailed information about the habitat, behaviour of the D. lustriae is also provided, and possible measures for its conservation are suggested.

Three species belonging to the genus Dolichopoda (Orthoptera; Rhaphidopohoridae) are known so far from the Peloponnese, all endemic to the area. In particular, D. matsakisi is known from two mountains in the North, while D. dalensi is present in the east region. The third species, D. unicolor, is distributed in the southern part of the Peloponnese, inhabiting caves on Mt Taygetos and Mani Peninsula. Recently, extensive sampling work in most of the Peloponnese has led to the discovery of new taxa, morphologically differentiated by the above three known species. To investigate the delimitation of the Peloponnesian species of Dolichopoda, we performed both morphological and molecular analyses. Morphological analysis was carried out by considering diagnostic characters generally used to distinguish different taxa, as the shape of epiphallus in males and the subgenital plate in females. Molecular analysis was performed by sequencing three mitochondrial genes, 12S rRNA, 16S rRNA, and COI, and one nuclear gene, 28S rRNA. Results from both morphological and molecular analyses were used to revise the taxonomic arrangement of the Peloponnesian species. On the whole, we were able to distinguish seven lineages of Peloponnesian Dolichopoda species, of which D. kofinasi n.sp., D.epidavrii n.sp., D. poseidonica n.sp., and D. propanti n.sp. are described as new species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:857875CB-22B9-4CFC-9B7F-3FDDFC47A4E6

Microtachycines tamdaonensis Gorochov, 1992 Fig. 1 Microtachycines tamdaonensis Gorochov & Storozhenko, 1992: 29. Material examined Holotype VIETNAM • ♂; Vinh Phuc Province, Tamdao; 9–18 Nov. 1990; A.V. Gorochov leg.; ZIN. Paratype VIETNAM • 1 ♀; same collection data as for holotype; ZIN. Distribution Vietnam (Tamdao). Remarks We examined the type specimens of Microtachycines tamdaonensis in ZIN and discussed with Dr A.V. Gorochov. We are sure that the male tenth abdominal tergite has a large outgrowth in the middle and the male epiproct is semicircular. Moreover, we examined the type specimens of M. elongatus and M. trispinosus in SEMCAS. All abdominal tergites of the two species have no outgrowths, but they have an extended epiproct. Therefore, we establish a new genus, Megatachycines gen. nov., and transfer M. elongatus and M. trispinosus to it.
