Taxonomic study on fourteen symphytognathid species from Asia (Araneae, Symphytognathidae)

Fourteen symphytognathid species belonging to three genera are examined, including the descriptions of eight new species and two new genera from China, Vietnam, Thailand and Myanmar: Patu Marples, 1951: P.catba S. Li & Lin, sp. nov. (♂, Vietnam), P.dakou S. Li & Lin, sp. nov. (♂♀, China), P.damtao S. Li & Lin, sp. nov. (♂, Vietnam), P.jiangzhou S. Li & Lin, sp. nov. (♀, China), P.jidanweishi Miller, Griswold & Yin, 2009 (♂♀, China), P.nagarat S. Li & Lin, sp. nov. (♂♀, Thailand), P.nigeri Lin & S. Li, 2009 (♀, China), P.putao S. Li & Lin, sp. nov. (♀, Myanmar), P.qiqi Miller, Griswold & Yin, 2009 (♀, China) and P.xiaoxiao Miller, Griswold & Yin, 2009 (♂♀, China); Kirinua S. Li & Lin, gen. nov.: K.maguai S. Li & Lin, sp. nov. (♂♀, China) and K.yangshuo S. Li & Lin, sp. nov. (♂♀, China); Swilda S. Li & Lin, gen. nov.: S.longtou (Miller, Griswold & Yin, 2009), comb. nov. (♂♀, China) is transferred from Crassignatha Wunderlich, 1995 and S.spinathoraxi (Lin & S. Li, 2009), comb. nov. (♂♀, China) is transferred from Patu. Diagnoses, descriptions and illustrations are provided for new taxa, as well as a distribution map. The males of P.xiaoxiao and S.longtou are described for the first time. Type specimens of P.jidanweishi, P.nigeri, P.qiqi, P.xiaoxiao, S.longtou and S.spinathoraxi are re-examined and photographed. All Asian Patu species are revised and two species, P.kishidai Shinkai, 2009 and P.bispina Lin, Pham & S. Li, 2009, are transferred to Crassignatha and proposed as new combinations: Crassignathakishidaicomb. nov. and C.bispinacomb. nov. In addition, DNA barcodes and genetic distances of ten species treated in this paper were obtained to confirm identification.
