PARATYPE: CHINA, Guangxi Province: Nanning, Daming Moutain, 27.v.2011, Tingting Zhang (1 ♂, 1 ♀, CAU). Distribution. Oriental: China (Guangxi). Remarks. Cothornobata zhangae is similar to C. paieroi sp. nov. and C. pugnoa sp. nov., but differs in having the fore tarsus blackish-brown, the upper occiput with a big triangular dark yellow spot at middle, the genital fork with a distinct and finger-like basal tubercle, arm about 1.2X as long as base, thick basally and slender before apex, and the distiphallus slightly longer than the phallapodeme. Etymology. This species is named after the type collector, Dr. Tingting Zhang.
