A review of six linyphiid spiders described from China by Dr E. Schenkel (Araneae: Linyphiidae)

According to Platnick's catalogue (2004) seven of the sixteen linyphiid spiders described from China by Dr E. Schenkel have not been re-examined since their original descriptions. This paper gives new information about them, except for Lepthyphantes kansuensis Schenkel, 1936, the type material of which could not be located. Erigone amdoensis Schenkel, 1963 and E. changchunensis Zhu & Wen, 1980 are herein regarded as junior synonyms of E. sinensis Schenkel, 1936. A new genus, Denisiphantes, is erected for Lepthyphantes denisi Schenkel, 1963. Lepthyphantes bonneti Schenkel, 1963, which was transferred to Incestophantes Tanasevitch, 1992 by Saaristo & Tanasevitch (2000), is here transferred to Tchatkalophantes Tanasevitch, 2001, and Lepthyphantes riyueshanensis Zhu & Li, 1983 is placed in its synonymy. Furthermore, Tmeticus yunnanensis Schenkel, 1963 is regarded as a junior synonym of Hylyphantes graminicola (Sundevall, 1830), while Perimonoides potanini Schenkel, 1963 is regarded as a nomen dubium. Besides Hylyphantes graminicola, all remaining valid species treated in this paper are redescribed and illustrated.
