A survey of pholcid spiders (Araneae, Pholcidae) from Guiyang, Guizhou Province, China.

The family Pholcidae C.L. Koch, 1850 is highly diverse in Guizhou Province, southwestern China, and currently contains four genera and 22 species. Nevertheless, the distribution of pholcid spiders is conspicuously patchy in Guizhou. Species from Guiyang are poorly studied, and only Pholcusspilis Zhu & Gong, 1991 has been recorded. A survey was undertaken for the first time to study the pholcids in Guiyang. A total of four species are reported, comprising Belisanayuhaoi Yang & Yao, sp. nov. and three other species: Leptopholcustanikawai Irie, 1999 (new record for Guiyang), Pholcusspilis Zhu & Gong, 1991 and Spermophorasenoculata (Dugès, 1836) (new record for Guizhou).
