Jurataenionema Liu and Ren
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

Jurataenionema stigmaeus Liu and Ren, sp. nov.
No full textJurataenionema stigmaeus Liu and Ren, sp. nov. Figs. 3–5 Etymology. From Latin stigmaeus, refers to the presence of a fuscous stigma in the terminal space of forewings. Materials. Holotype, female. CNU, NMDHG 183, a well–preserved body with part of wings, and paratypes (Imagoes) from the same locality: CNU, NMDHG 99, and CNU, NMDHG 184–187. Description. Length of body 14 mm, to tip of wings 18 mm. Head large, triangular, the posterior part not twice as wide as the anterior; antennae long. Prothorax narrow, two–thirds of the mesothorax; mesothorax and metathorax developed, same width. Legs robust. Forewings 15 mm length. Sc connected to R at almost two–thirds total wing length; c–r far from the Sc tip, grey pterostigma present; Rs forks distinctly after the r–rs, and its anterior branch forks again close to the Rs forks. Crossvein r–rs short, almost perpendicular to Rs. M appears 2 –branched, forking from the proximal 1 / 3 of the wing, its branches are nearly twice as long as Rs branches, rs–m straight, connects Rs before r–rs and terminates at the one fifth of MA. Crossvein m–cua S–shaped, connecting M stem or MP, and terminated the stem of CuA. CuA forks close to M forks, with long anterior branch. 4 crossveins at the median area, 7 crossveins at the cubital areas. Abdomen with 10 visible segments, almost 1.7 times as long as thorax. Ninth sternite produced as a subgenital plate, the median tongue upturned, triangular. Cerci short, eight or nine segments. Remarks. The new species J. stigmaeus differs from the type species by the defined pterostigma.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 3-4, 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
Full text linkThe 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
A Subband-Selective Broadband GSC with Cosine-Modulated Blocking Matrix
Full text linkIn this paper, a novel subband-selective generalized sidelobe canceller (GSC) for partially adaptive broadband beamforming is proposed. The columns of the blocking matrix are derived from a prototype vector by cosine-modulation, and the broadside constraint is incorporated by imposing zeros on the prototype vector appropriately. These columns constitute a series of bandpass filters, which select signals with specific angles of arrival and frequencies. This results in highpass-type bandlimited spectra of the blocking matrix outputs, which is further exploited by subbands decomposition and suitably discarding the low-pass subbands prior to running independent unconstrained adaptive filters in each non-redundant subband. By these steps, the computational complexity of a GSC implementation is greatly reduced compared to fully adaptive GSC schemes, while performance is comparable or even enhanced due to subband decorrelation in both spatial and temporal domains
