Tregouboviopsis Guo, Xu & Huang 2017, gen. nov
No full textGenus Tregouboviopsis Guo, Xu & Huang, gen. nov. Type species: Tregoubovia perradialis Xu, Huang & Du, 2012. Diagnosis. Ptilocodiidae medusae spherical; without tentacles; bell margin with nematocyst ring from which originate didermic centripetal tracks running meridionally on exumbrella; manubrium large, mouth quadratic with simple and long, unbranched oral tentacles, arising above mouth rim, unarmed terminal nematocyst clusters, and with ring nematocysts along the whole length of the oral tentacles; gonads very large, covering perradial on manubrium well, with mescenteries; without ocelli. Hydroid. Unknown. Remarks. The species Tregoubovia perradialis Xu, Huang & Du, 2012 is originally described under the genus Tregoubovia by the distinctness of simple unbranched oral tentacles, without marginal tentacles and exumbrella with didermic centripetal tracks. By reexamining the type specimens, its positions of oral tentacles and gonads are different from Tregoubovia atentaculata Picard, 1958, the type species of the genus. T. atentaculata has 4 oral arms extending directly from the perradial corners of mouth margin, with one terminal nematocyst clusters; gonads on interradial manubrium (Fig. 5), while T. perradialis has 4 oral tentacles arising above mouth rim, unarmed terminal nematocyst clusters, and with ring nematocysts along the whole oral tentacles; gonads on perradial manubrium (Figs 6–7). Therefore, the species T. perradialis is removed from the genus Tregoubovia and a new genus Tregouboviopsis Guo, Xu & Huang, gen. nov. is erected to accommodate it. Etymology. The genus name is derived from the Latin tregouboviopsis, meaning Tregoubovi-opsis, referring to external characters of both genera are nearly resemble.Published as part of Wang, Lianggen, Du, Feiyan, Xu, Zhenzu, Huang, Jiaqi & Guo, Donghui, 2017, Taxonomical notes on the family Ptilocodiidae (Anthomedusae) from the central and southern of South China Sea, with a new genus and a new species, pp. 236-242 in Zoological Systematics 42 (2) on pages 239-240, DOI: 10.11865/zs.201713, http://zenodo.org/record/461701

Istiochrysis Rosa & Xu, gen. nov. is similar to the Nearctic and Neotropical genus Caenochrysis Kimsey & Bohart, 1981, and the Palaearctic and Oriental genera Chrysidea Bischoff, 1913 and Trichrysis Lichtenstein, 1876. However, this new genus can be separated from Caenochrysis, Chrysidea and Trichrysis by male genitalia with extended longitudinal crest on aedeagus (Figs 1 A– 1 C); apex of aedeagus enlarged and folded laterally (Figs 1 A, 1 B) (not enlarged in the other genera and tapering in Caenochrysis); facial fovea between antennal socket and lower margin of eye hardly visible and shallowly depressed and finely punctate (Figs 2 A, 2 B) (usually deeply depressed in Caenochrysis); pronotum without sublateral carina (Fig. 3 A) (usually with sublateral carina in Trichrysis); fore wing discoidal cell with thin and completely sclerotised outer vein (faint in Chrysidea); apex of T 3 without teeth (laterally dentate and medially undulate in Chrysidea, tridentate in Trichrysis); S 2 with large, subrectangular, black spots extending to lateral margins (Fig. 3 B), somehow similar to those in the genus Praestochrysis Linsenmaier, 1968 (small, suboval, not extending to lateral margins in Caenochrysis; suboval and separated in Chrysidea (Fig. 3 D), subtriangular and medially fused or nearly so in Trichrysis (Fig. 3 C)) (Bohart & Kimsey 1982; Linsenmaier 1984; Rosa & Xu 2015; Rosa et al. 2016 a) (Fig. 2 D). Description. Male. Head broader than high. Scapal basin with shallow depression on each side between antennal socket and lower margin of eye; depression visible only under certain angle (Figs 2 A, 2 B); bottom of depression filled with micro-punctures and densely setose. Scapal basin topped by TFC (Figs 2 A, 4 B); scapal basin with white setae, especially along lateral sides (Fig. 2 A). F 1 l/w> 3; MS= 1 MOD. Genal carina developed from gena to mandible. Subgenal area well defined. Median ocellus not lidded. Vertex without posterior depression beneath posterior ocellus. Mandible unidentate. Pronotum nearly as long as mesoscutellum with deep lateral depression, without sublateral carina. Mesopleuron with large episternal sulcus and scrobal sulcus (Fig. 4 D); area between episternal sulcus and scrobal sulcus large and subtriangular. Metanotum with raised median area. Fore wing with thin but completely sclerotized outer veins of discoidal cell (Fig. 3 A). T 2 and T 3 with shallow median longitudinal carinae (Fig. 4 E). Apex of T 3 without teeth, but with shallow concavity, thus appearing bilobate (Fig. 4 F); pit row well developed with enlarged and partly fused pits (Fig. 4 F). Black spots on S 2 elongate, fused along lateral margins (Fig. 3 B) and distinctly separated mesally. Male genitalia with gonostyle of gonocoxa elongate and slender, aedeagus with enlarge longitudinal crest, well visible in lateral view (Fig. 1 C). Female. Unknown. Biology. Unknown. Distribution. China (Yunnan). Etymology. From Greek noun istion (= sail), referring to the unique subsidiary structure longitudinally placed on aedeagus, looking like a sail in lateral view. The gender is feminine.Published as part of Rosa, Paolo, Feng, Jun & Xu, Zai-Fu, 2016, Istiochrysis gen. nov., a new chrysidid genus from Oriental China (Hymenoptera, Chrysididae), pp. 591-597 in Zootaxa 4111 (5) on page 592, DOI: 10.11646/zootaxa.4111.5.5, http://zenodo.org/record/26366

Leptopareia Rosa & Wei & Notton & Xu 2016, gen. nov.
No full textGenus Leptopareia Rosa & Xu, gen. nov. (Figs 1C, 2A, 3A, 7A – 9F, 10A – 11D) Leptopareia Rosa & Xu, gen. nov. Type species: Hedychrum borneanum Cameron, 1908: 61. Diagnosis. The genus Leptopareia gen. nov., is closely related to Holophris Mocsáry, but it can be easily separated by the combination of following characteristics: head, in lateral view, with indistinct subgenal area and subgenal carina (Fig. 3A) (distinct in Holophris (Fig. 3B); compare Fig. 65 and Fig. 66b in Kimsey & Bohart 1991); MS short, 0.2–0.5 MOD (longer, 1.0–1.5 MOD in Leptopareia); MS not bisected by genal carina (bisected in Holophris); head elliptical, in frontal view (Figs 8B, 9B, 10B, 11B) (with convex upper profile in Holophris (Figs 4B, 5B, 6B)); inner margin of eye sinuous (straight in Holophris); pronotum laterally with deep fovea (without lateral fovea in Holophris); mesoscutum with distinct and complete notauli (indistinct in Holophris); notaular pits deep and round (usually narrow in Holophris); double omaulus subparallel (triangularly shaped in Holophris); TPC extending to apex of PA (below PA in Holophris); fore wing with elongated C, Sc+R and M, and pterostigma positioned over half length of anterior margin (Fig. 2A) (with shortened C, Sc+R and M, and M considerably arched, pterostigma positioned at less than half length of anterior margin in Holophris); apex of T3 with or without distinct median notch (without distinct median notch in Holophris). Description. Mandible tridentate; scapal basin deep and usually transversely striated, at least laterally; face with long white setae (up to 1 MOD); head elliptical, in frontal view; gena very narrow under lower margin of eye, not carinate (Fig. 3A); subgenal area indistinct (Fig. 3A); MS <1 MOD and not bisected by genal carina (Fig. 3A); inner margin of eye usually sinuous (Fig. 7B); occipital area, pronotum and mesoscutum medially impunctate or with sparse tiny punctures (Figs 7C, 8C, 9C, 10C, 11C); notauli distinct (Figs 7C, 8C, 9C, 10C, 11C); notaular pits deep and rounded; mesoscutellum usually without anterior foveae (with exception of L. congoensis (Fig. 11C)); mesopleuron sub-rectangular with subparallel double omaulus (Figs 2C, 7A, 8A, 9A, 10A, 11A); TPC extending to apex of PA (Fig. 1C); propodeal angle subparallel and not sharply developed (Fig. 9C); tarsal claw with three to four teeth; apex of T3 with wide semitransparent rim (± 1 MOD), with or without median notch (Figs 7F, 8F, 9F, 10F, 11F). Biology. Unknown. Distribution. Leptopareia Rosa & Xu, gen. nov. is currently known from the Afrotropical and Oriental Regions. Species included. At present, this genus includes seven species: L. borneana (Cameron, 1908), comb. nov., L. luzonensis sp. nov. and L. purpurea (Smith, 1860), comb. nov. (Oriental); L. abyssinica (Mocsáry, 1914), comb. nov. (Figs 10A–10D), L. confusa (Kimsey, 1988), comb. nov., L. congoensis (du Buysson, 1900), comb. nov. (Figs 11A–11D), and L. kalliopsis (Zimmermann, 1961), comb. nov. (Afrotropical). Etymology. The name Leptopareia is derived from the Greek words λεππτός (leptós = thin) and παρειά (pareia = gena) and refers to the thin and narrow gena with indistinct subgenal area. The gender is feminine.Published as part of Rosa, Paolo, Wei, Na-Sen, Notton, David & Xu, Zai-Fu, 2016, Revision of the Oriental genus Holophris Mocsáry, 1890 and description of the genus Leptopareia Rosa & Xu, gen. nov.

Pseudelzalia Yu & Xu 2014, gen. nov.
No full textGenus Pseudelzalia gen. nov. Diagnosis Xyalidae with six labial papillae and 10 cephalic setae, cylindrical buccal cavity, elongate (>2 a.b.d.) spicules, and conico-cylindrical tail devoid of terminal setae. Etymology Composition of the Greek prefix pseudo- (false) and the generic name Elzalia, referring to the similarity of the genus to Elzalia. Feminine gender. Type species Pseudelzalia longiseta gen. nov., sp. nov. Familial assignment and comparison with related genera and species The new species Pseudelzalia longiseta sp. nov. described below is obviously a member of the family Xyalidae characterized by transversely striated cuticle, usually 10 cephalic setae, and a single anteriorly outstretched ovary to the left of the intestine. Within the family Xyalidae, Pseudelzalia longiseta sp. nov. is very similar to members of Elzalia Gerlach, 1957 in having the labial papillae, large cylindrical buccal cavity and elongate spicules. However, the new species possesses a character clearly different from all known species of Elzalia, namely, the tail devoid of terminal setae versus with three terminal setae in Elzalia (Figure 1A, E). The structure of the tail is a significant character at the genus level within the family Xyalidae, in which the two largest genera, Daptonema Cobb, 1920 and Theristus Bastian, 1865, are separated only by the tail morphology (conico-cylindrical with terminal setae versus conical without terminal setae) (Warwick et al. 1998). Pseudelzalia longiseta sp. nov. is also similar to the monotypic genus Parelzalia Tchesunov, 1990 which, however, has a conical buccal cavity with domed anterior end, shorter spicules of about 1 a.b.d. and in particular the presence of terminal setae (Tchesunov 1990). Accordingly, we propose Pseudelzalia as a new genus. Except for the tail morphology, Pseudelzalia differs from Daptonema and Theristus also by the cylindrical buccal cavity (versus conical) and elongate spicules (>2 a.b.d. versus <2 a.b.d.). The presence of long caudal setae in the new species Pseudelzalia longiseta is another striking character that is absent in the genera Elzalia, Daptonema and Theristus. However, only one species is described for the new genus and such a character has never been regarded as a generic character within the family Xyalidae. Hence, we consider it a specific character for Pseudelzalia at the current state of knowledge.Published as part of Yu, Tingting & Xu, Kuidong, 2014, Two new nematodes, Pseudelzalia longiseta gen. nov., sp. nov. and Paramonohystera sinica sp. nov.

Jianghuaimon Zhao & Xu & Huang 2022, gen. nov.
No full textGenus Jianghuaimon gen. nov. [Chinese name: ü淮ēøĸ] Type Species. Jianghuaimon dabiense gen. nov. et sp. nov., by present designation. Diagnosis. Small sized (CW <25 mm). Carapace subquadrate, flat, dorsal surface pitted (Fig. 1); epigastric cristae low; not confluent with postorbital cristae (Fig.1); external orbital angle bluntly triangular, almost straight (Fig. 1). Epistomial median lobe narrowly triangular (Fig. 2A). Maxilliped III with relatively broad ischium, exopod reaching beyond anterior edge of ischium, with long flagellum (Fig. 3A). Cheliped palm surface relatively rugose (Fig. 3F–G). Male anterior thoracic sternum wide, width 1.8 × length (Fig. 2B). Male pleon broadly triangular, tip of telson semicircular (Fig. 2C). G1 generally slender, pointing anterolaterally, terminal segment large and stout with wide opening at truncate tip, inner margin rounded (Fig. 3C–E, H–I). G2 with subquadrate basal segment (Fig. 3B). Female vulva ovate, large, located within sternite VI (Fig. 2F). Etymology. The genus name is an arbitrary combination of the zoogeographic location of the type locality, the Jianghuai freshwater zoogeographic dominion (Huang et al. 2020a), and the genus name, Potamon Savigny, 1816. Gender: neuter. Distribution. Huo Shan county, Lu’an city, Anhui province, China; Yingshan County, Huanggang City, Hubei Province, China. Remarks. Jianghuaimon gen. nov. has a rather unexceptional external appearance and most closely resembles Bottapotamon Türkay & Dai, 1997 and Neilupotamon Türkay & Dai, 1997 in its small size (CW <30 mm), relatively flat carapace with regions distinct, bluntly triangular external orbital angle and slightly unequal chelipeds. Jianghuaimon gen. nov. also resembles Huananpotamon Dai & Ng, 1994 in general external appearance to some extent, its relatively small size (CW <30 mm), having stripe patterned ambulatory legs and a distinctive ovalshaped gold-colour pattern on the third maxilliped. However, Jianghuaimon gen. nov. markedly differs from Bottapotamon, Huananpotamon and Neilupotamon by its unique G1 structure, which is pointed anterolaterally, subterminal segment slightly curved inwards, terminal segment large and very stout, inner margin strongly convex, tip truncated with wide opening almost same width as terminal segment (Fig. 3C–E, H–I). In contrast, the G 1 in Bottapotamon is pointed anteromedially, with the subterminal segment generally straight, terminal segment large and slender, inner margin concave, tip truncated with opening smaller than terminal segment width (cf. Gao et al. 2019: fig. 5); in Huananpotamon, pointed anteriorly or anteromedially, with the distal part of subterminal segment neck-shaped, terminal segment slender, inner margin with flap or projection, with small opening at pointed tip (cf. Dai 1999: pls. 63–73); and in Neilupotamon, pointed anterolaterally, with the subterminal segment generally straight, terminal segment stout, inner margin almost straight to slightly convex, tip truncated with wide opening almost as wide as the terminal segment (cf. Dai 1999: pls. 201–204). Jianghuaimon gen. nov. can further be separated from Bottapotamon, Huananpotamon and Neilupotamon by differences in the carapace, male anterior thoracic sternites and male telson. See Table 1 for detailed comparisons. Moreover, Jianghuaimon gen. nov. was found to be syntopic with Longpotamon depressum, but can immediately be distinguished by its smaller size (CW <25 mm) (versus CW <50 mm in the latter), carapace anterolateral margin with 12–15 granules (Fig. 1A) (versus serrated, with 15–18 granules in the latter; Dai 1999: pl. XXII fig. 2), granules on anterolateral margin low and inconspicuous (Fig. 1A) (versus relatively large conspicuous in the latter; Dai 1999: pl. XXII fig. 2) and its G1 terminal segment large, stout, with rounded inner margin and wide opening at truncate tip (Figs. 3C–E, H–I) (versus relatively small G1 terminal segment with bifurcated tip in the latter; Dai 1999: pl. 179).Published as part of Zhao, Jun-Da, Xu, Yi-Yang & Huang, Chao, 2022, Jianghuaimon dabiense gen. nov. et sp. nov (Crustacea: Decapoda: Potamidae), a new genus and new species of freshwater crab from eastern-central China, pp. 431-440 in Zootaxa 5168 (4) on page 432, DOI: 10.11646/zootaxa.5168.4.3, http://zenodo.org/record/689974
