No full textGenus Jurataenionema Liu and Ren, gen. nov. Type species. Jurataenionema inornatus Liu and Ren, sp. nov. Etymology. The generic name is taken from the combination of Jura and T aenionema (a genus of Taeniopterygidae) Species included. The type species J. inornatus Liu and Ren, sp. nov. and J. stigmaeus Liu and Ren, sp. nov. Diagnosis. Wings are macropterous, translucent. No additional veinlets on the costal area, c–r present or very faint, sometimes grey pterostigma presents in the terminal space of forewings; Rs with three branches, M and CuA with two long branches, and fork at level of midlength of Rs stem; 5–8 crossveins in the median and cubital areas. Ninth sternite produced, with a median tongue–like erect and then bent forward extension tapering to around or cuspidal tip, tenth tergite transversely wide, sclerotized. Cerci short, eight to ten segments. Remarks. The new genus Jurataenionema differs from the extant genera by the longer cerci and long branches of CuA; differs from the extinct Gurvanopteryx by Rs with three branches and the longer first segment of hind tarsus; differs from the extinct Positopteryx by c–r present, Rs with three branches.Published as part of Liu, Yushuang, Sinitshenkova, Dong Ren Nina D. & Shih, Chung Kun, 2007, The oldest known record of Taeniopterygidae in the Middle Jurassic of Daohugou, Inner Mongolia, China (Insecta: Plecoptera), pp. 1-8 in Zootaxa 1521 on page 2, DOI: 10.5281/zenodo.17745

Chenxiella Liu, Ren & Prokop, 2009, gen. nov.
No full textGenus Chenxiella gen. nov. Type species. Chenxiella liuae sp. nov. Etymology. In honor of Miss Chenxi Liu, who is a young paleoentomologist studying fossil hymenopterans at Captial Normal University, the collector of the type specimen. Feminine in gender. Diagnosis. Forewing: ScP anteriorly reticulate, ending on RA at distal third of wing; division RA and RP in basal fourth of wing, RA reaching anterior wing margin near apex; RP almost parallel to RA, and pectinate with one anterior branch and seven main posterior, most of them generally possess 2–3 secondary branches covering the whole wing apex, stem M + CuA long, division M and CuA distinct basally of the division of RA and RP; stem M diverging distally of division RA and RP; MA rather long, partly fused with RP, and then deeply bifurcated; simple MP terminally twigged; convex CuA emerging from convex M + CuA near the basal sixth of the wing, distally fused with CuPa; CuA fused with M at the very base of the wing, CuA + CuPa with eight main branches bearing two thirds of whole posterior wing margin; CuP divided into two branches (CuPa and CuPb), CuPa simple, fused with distal free part of CuA, area between CuPa and CuPb broad with a network of cells; CuPb divided into CuPbα and CuPbβ, CuPbα distally vanishing in a network. 1 A with two terminal branches, and close to CuPbβ, 2 A pectinate with five main branches; anal area distictly networks of cells and cross-veins between main veins reticulate. Remarks. The new genus is very similar to Sinopteron Prokop & Ren, 2007, which was collected from the same locality and horizon in Xiaheyan Village. It differs from Chenxiella mainly by the combination of the following characters: (1) RP pectinated with one anterior branch and seven main posterior branches instead RP pectinated with two anterior branches and six main posterior branches in Sinopteron; (2) MA rather long and partly fused with RP, and then deeply bifurcated; instead MA deeply bifurcated, and anterior branch of MA partly connected with RP; and (3) CuPb terminally bifurcated instead simple, without terminal twigging in Sinopteron.Published as part of Liu, Yushuang, Ren, Dong & Prokop, Jakub, 2009, Discovery of a new Namurian archaeorthopterid from Ningxia, China (Insecta: Archaeorthoptera), pp. 63-68 in Zootaxa 2032 on page 64, DOI: 10.5281/zenodo.18629

Uloma (Uloma) intricornicula Liu, Ren & Wang, 2007 (Coleoptera, Tenebrionidae, Ulomini): Descriptions of the larva and pupa and new distributional records
No full textThe genus Uloma Dejean, 1821 (Coleoptera, Tenebrionidae, Ulomini) comprises more than 200 species and subspecies worldwide, 37 of which are recorded from China. However, the morphology of the immature stages of Chinese Uloma have been poorly documented. Up to now, larva and pupa descriptions are available for only one species, Uloma (Uloma) metogana Ren, 2004.The larva and pupa of Uloma (Uloma) intricornicula Liu, Ren & Wang, 2007, from southern China, are described and illustrated for the first time and are compared with those of U. (U.) metogana Ren, 2004. Differences between male and female pupae of this species are highlighted. New distributional data for U. (U.) intricornicula are also provided. Finally, 13 Uloma species from China are formally assigned to the nominated subgenus

Jurataenionema inornatus Liu and Ren, sp. nov.
No full textJurataenionema inornatus Liu and Ren, sp. nov. Figs. 1–2 Etymology. From Latin inornatus, means the wing luculent, without any stigma in the terminal space of forewings. Materials. Holotype, female. CNU, NMDHG 61, a well–preserved body with part of wings, and a paratype (imago) from the same locality: CNU, NMDHG 145. Description. Length of body 11–13 mm, to tip of wings 16–17 mm. Head large, almost triangle, the basal part is 1.5X as wide as the distal; antenna long, longer than body. Cervix preserved clearly, narrow. Prothorax transverse, two–thirds of mesothorax length. Forewings: 14–15 mm length. Costal area without additional veinlets, Sc terminates R nearly to two– thirds of the total wing length, c–r far from the Sc tip. Rs departs from R at one–sixth of the base, and forks distinctly after r–rs, its anterior branch forks again at the midlength. r–rs short, almost vertical to Rs, M bifurcates slightly basal of the midlength of wing, and its branches are nearly twice as long as Rs branches, rs–m straight, connects with Rs before r–rs and terminates at the one fifth of MA. Crossvein m–cua S–shaped, connecting M at the same level of M forks, and terminated the stem of CuA. Vein CuA forks basal to M forks, its anterior branch long, almost twice as long as the posterior branch, 5–8 crossveins at the median and cubital areas. Abdomen with 10 visible segments, slightly longer than head and thorax together. Ninth sternite produced, the median tongue upturned, narrowly round, tenth tergite transversely wide, sclerotized. Cerci short, its segments faint, about 8–10 segments. Legs long, coxa and trochanter wide, femur robust, nearly twice as wide as tibia, tibia slender, about 1.3X as long as femur, tarsus long, half a length of tibia, three segments are of almost the same length. Remarks. The new species J. inornatus resembles extant Mesyatsia thianshanica (Zhiltzova 1972) in venation, except Rs has three branches and there is no costal crossvein. In addition, no pterostigma exists, while it is present in M. thianshanica.Published as part of Liu, Yushuang, Sinitshenkova, Dong Ren Nina D. & Shih, Chung Kun, 2007, The oldest known record of Taeniopterygidae in the Middle Jurassic of Daohugou, Inner Mongolia, China (Insecta: Plecoptera), pp. 1-8 in Zootaxa 1521 on pages 2-3, DOI: 10.5281/zenodo.17745
Mirimordella Liu, Lu & Ren, 2007, gen. nov.
No full textGenus Mirimordella gen. nov. Type species: Mirimordella gracilicruralis sp. nov. Etymology. From the Latin prefix miri-, strange, and the genus Mordella Linnaeus 1758; gender feminine. Species included. Holotype species only. Diagnosis. Maxillary palpi linear, last segment without distinct enlargement. Scutellum long, triangular or rectangular. Elytra arched, sharply tapering on apical 1 / 3; apex pointed. Epicoxa present in front of hind coxal plate and immediately juxtaposed to metepisternum. Hind tibiae expanded apically, with oblique truncate apex, as long as femora; hind tarsi longer than tibiae. Abdomen with 5 visible abdominal segments. Comparisons. We assign this new genus to Praemordellinae based on agreement with the revised diagnosis of the subfamily. This new genus and the genus Praemordella share many characters including the wedgeshaped body, the body size, the sharply narrowing elytra, the pointed apex of elytra, and the abdomen extended beyond elytra, the hind coxae and femora less enlarged than modern mordellids, the apical ridges only on hind tibiae and tarsi, the simple penultimate segments of fore and middle tarsi, and simple claws. However, the new genus can be distinguished from Praemordella by the following: 5 visible abdominal segments, less developed hind femora, hind tarsi longer than tibiae, apices of hind tibiae oblique, tarsal formula 5 - 5 - 4, and presence of epicoxa anterior to hind coxal plate and immediately juxtaposed to metepisternum. This new genus differs from the genus Cretanaspis (Mordellinae) in the following: 5 visible abdominal segments, penultimate segments of fore and middle tarsi simple, hind tarsi longer than tibiae, and apices of hind tibiae oblique.Published as part of Liu, Ming, Lu, Wenhua & Ren, Dong, 2007, A new fossil mordellid (Coleoptera: Tenebrionoidea: Mordellidae) from the Yixian Formation of Western Liaoning Province, China, pp. 49-56 in Zootaxa 1415 on pages 51-52, DOI: 10.5281/zenodo.17569
