ABSTRACT: 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.
