On some Linyphiidae of China, mainly from Taibai Shan, Qinling Mountains, Shaanxi Province (Arachnida: Araneae) Author Tanasevitch, Andrei V. text Zootaxa 2006 1325 277 311 journal article 10.5281/zenodo.273569 a1367ba3-36b0-4cd4-9ce4-213ef0e4d62f 1175­5326 273569 Dicymbium sinofacetum sp. n. Figs 39–44 ? Araeoncus stigmosus Xia et al . 2001 : 164 (female only!). Material . Holotype ♂ ( SMF ), China , Qinghai Prov., Bei Shan National Park, 120 km NE Xining, 2300–2700 m , 23.V.–8.VI.1996 , leg. J. Martens. Paratypes : 1 ♂ , 5 Ψ ( SMF ), 2 Ψ ( ZMMU ), together with holotype ; 2 Ψ ( SMF ), China , Shaanxi Prov., S flanks of Taibai Shan, above Houshenzi, primary broadleaved forest, 2500–2600 m , 25.–26.VI.1997 , leg. J. Martens & P. Jäger. Diagnosis . The species is very closely related to the Siberian D . facetum (L. Koch 1879) , but differs by the non­expanded proximal part of the paracymbium, by the presence of a deep hollow at the base of the embolus, which is shorter than in D . facetum , as well as by the shape of the receptacula of the vulva. Like D . facetum , D . sinofacetum sp. n. has no trichobothrium on Mt IV. Araeoncus stigmosus Xia, Zhang, Gao, Fei, Rui & Kim 2001 was described from Gansu Province, China from both sexes ( Xia et al. 2001 ). According to the published figures, the female of this species belongs to the genus Dicymbium Menge 1868 , not Tibioploides Eskov & Marusik 1991 , and is probably referred to D. sinofacetum sp. n. NB: The female of D . facetum has not yet been described. Etymology . The species name sinofacetum is a combination of Latin “Sinae” and “ facetum ”, emphasizing that the new Chinese species is closely related to Dicymbium facetum (L. Koch 1879) ; adjective.
