Type material. HOLOTYPE: Ƥ, CHINA, Yunnan, Zhaotong, Xiaocaoba, 2009. IX. 15, Tingting Zhang. PARATYPE: 1 Ƥ, CHINA, Yunnan, Zhaotong, Luohanba, 2009. V. 29, Liangming Cao.

Distribution. China (Yunnan)

Etymology. The specific name refers to the type locality Zhaotong county.

Remarks. This new species is somewhat similar to Bittacomorphella thaiensis Alexander , but can be easily separated from it by the body being much longer, 1 st tarsomere of the foreleg being white basally. In Bittacomorphella thaiensis Alexander , the 1 st tarsomere of the foreleg is entirely black ( Alexander 1953).
