Diagnosis and description. Patellae of male palp (lateral view) with a strong seta that is located on a swollen and convex base. For more detail diagnosis and description, see Xu, Li & Wang, 2008. Comments. Lineacoelotes was originally described for five species: L. bicultratus (Chen, Zhao & Wang, 1991), L. funiushanensis (Hu, Wang & Wang, 1991), L. nitidus (Li & Zhang, 2002), L. longicephalus Xu, Li & Wang, 2008, and L. strenuus Xu, Li & Wang, 2008. Based on these data and the new species described below, the genus is distributed in central (Henan, Hubei), southwestern (Chongqing, Guizhou, Sichuan) China.Published as part of Li, Bing, Zhao, Zhe, Chen, Haifeng, Wu, Zhiyan & Li, Shuqiang, 2019, New species of the coelotine spider genus Lineacoelotes (Araneae: Agelenidae) from China, pp. 351-363 in Zootaxa 4623 (2) on page 352, DOI: 10.11646/zootaxa.4623.2.9, http://zenodo.org/record/325550

Distribution. China (Fujian and Guangxi). Remarks. The species was described from Wuyishan Mountain of Fujian Province (Li et al. 2013b; Qin et al. 2013), and hitherto it was known only from the type locality. The present two male specimens agree well with the type materials and further topotypes. The specific characters are shown on Fig. 33: characteristic head pattern, strongly sclerotized tube, relatively short sac with distinct, strong apical spines and subapical field of fine spines. These are the first reports from Guangxi.Published as part of MO, RAORAO, WANG, GUOQUAN, YANG, DING, LI, WEIHAI & MURÁNYI, DÁVID, 2022, Review and contribution to the stoneflies (Insecta: Plecoptera) of Guangxi Zhuang Autonomous Region, China, with new species and new records from South China, pp. 1-80 in Zootaxa 5176 (1) on page 40, DOI: 10.11646/zootaxa.5176.1.1, http://zenodo.org/record/702535
Striatanus Li & Wang
No full textStriatanus Li & Wang Striatanus Li & Wang 1995: 189. Type species: Striatanus curvatanus Li & Wang, by original designation. Black with yellow markings, labium and legs yellow. Macropterous. Head, pronotum and scutellum sparsely pubescent. Head conically produced in front of eyes, about as long as combined length of pronotum and mesonotum. Crown with median longitudinal and lateral marginal prominent carinae converging at apex with median carina on frontoclypeus. Ocelli placed in front of eyes ventral to lateral carina and carina that arises in front of eye traverses below ocellus and joins lateral carina thus enclosing the ocellus in a triangular space; surface of crown in apical 0.75 transversely rugose, basal 0.25 longitudinally rugose punctate. Frontoclypeus with lateral arched carina; clypellus broad basally tapered apically, coarsely granulate. Both gena and narrow elongate lorum rugose punctate. Pronotum gradually posteriorly widened, broader than head, transversely rugose punctate, lateral margin carinate. Mesonotum with basal triangles shagreen, rest unevenly rugose punctate, scutellum transversely rugose. Forewing with claval veins fused near middle to almost 0.33 length of outer claval vein, venation prominent, raised. Forefemur with three enlarged macrosetae on row AV followed by finer hair-like setae; intercalary row setae slightly stouter, row AM with scattered microsetae, AM1 well developed. Hind femur distal macrosetae 2+2+1. Hind tibial macrosetae AD 12, AV 18, PD 24; setae on row AD with 3–5 short setae interspersed between two large ones. Hind basitarsus apical transverse row with three spine-like platellae. Male pygofer with dorsal basal fracture, devoid of macrosetae, with ventral process slightly exceeding height of posterodorsal margin, valve extended obliquely dorsally. Subgenital plate with basal segment, with multiserial macrosetae along median region and with lateral row of slender marginal setae. Style short, apophysis foot-shaped. Connective Y-shaped with stem about 1.5 times as long as arms. Aedeagus with plate-like apodemes with median ridge; shaft with complex dorsolateral lobes and often with ventral angular projection. Female with ovipositor projecting well beyond pygofer but not beyond folded forewings. Remarks. Striatanus Li & Wang can readily be recognised by the fused claval veins. It closely resembles Riseveinus Li but the latter differs in not having a ventral pygofer process in the male. Some undescribed species of Vangama also have medially fused claval veins but can be differentiated by the greatly elongated head with both dorsal and ventral laminate keels which are lacking in Striatanus.Published as part of Viraktamath, C.

Another remark on a result of Ding-Jost-Li-Wang
Full text linkLet be a compact Riemann surface, be a positive smooth function
on . It is well known the functional achieves its minimum under
Ding-Jost-Li-Wang condition. This result was generalized to nonnegative by
Yang and the author. Later, Sun and Zhu (arXiv:2012.12840) showed
Ding-Jost-Li-Wang condition is also sufficient for achieves its minimum
when changes sign, which was reproved later by Wang and Yang (J. Funct.
Anal. 282: Paper No. 109449, 2022) and Li and Xu (Calc. Var. 61: Paper No. 143,
2022) respectively using flow approach. The aim of this note is to give a new
proof of Sun and Zhu's result. Our proof is based on the variational method and
the maximum principle.Comment: 13 pages. To appear on Proc. AM
