Holotype, male, China: Guizhou Province, Mayanghe National Nature Reserve, at light, 30 Sep. 2007, coll. Yue-hua Song. Paratypes: two females, same date as holotype.
The new species is similar to Kapsa distalis Sohi & Mann (1992), but the aedeagus has a pair of atrial processes and apical processes (Figs 15, 16) and the dorsal pygofer appendage is not apically bifurcate (Fig. 13).
The specific name is derived from the Latin prefix “quadri-” and the Latin word “spina”, referring to the aedeagus with four processes (Figs. 15, 16).
