Type material. Holotype: ♂, CHINA: Guizhou Prov., Weining County, Meihua, 3 August 2017, coll. Hongxing Li (GUGC); paratypes: 23♂♂ 14♀♀, same data as holotype (GUGC).

Etymology. The new species name combines the Latin prefix “ bi- ” (two) with “ processus ”, referring to the base of aedeagus with a pair of dorsal linear processes.
