They belong to three species groups and include six newly described species: Pholcusqiaojia Li, Li & Yao, sp. nov. (♂♀, Yunnan) in the bidentatus group; P.aba Li, Li & Yao, sp. nov. (♂♀, Sichuan) and P.wenchuan Li, Li & Yao, sp. nov. (♂♀, Sichuan) in the crypticolens group; P.mengding Li, Li & Yao, sp. nov. (♂♀, Sichuan), P.miyi Li, Li & Yao, sp. nov. (♂♀, Sichuan) and P.yaan Li, Li & Yao, sp. nov. (♂♀, Sichuan) in the yichengicus group. P.bidentatus Zhu, Zhang, Zhang & Chen, 2005 is recorded from Yunnan for the first time and P.kunming Zhang & Zhu, 2009 is recorded from Guizhou and Sichuan for the first time. Detailed diagnoses, descriptions, photomicroscope images, and DNA barcodes of all newly described species are provided.
