Anal collar processes elongate, 0.5 times as long as pygofer, of uniform width. Subgenital plates narrow and long with prominent macrosetae on subapical margin. Apophysis of style ( Fig. 37 ) with outer margin bearing approximately 19-20 lateral setae. Aedeagal shaft ( Fig. 38 ) elongate, nearly straight, rounded apically, subapex two pairs of unequal processes surface about between gonopore, gonopore situated at subapex on posterior surface ( Fig. 39 ).

Female. Unknown.

Measurements (mm). Male: body length 5.8, face length 1.375, width 1.5; distance between ocelli 0.5; distance from ocellus to eyes 0.25; medial length of pronotum 0.55, width 1.5; scutellum length 0.8, width 1.1.

Material examined. Holotype: male, China, Sichuan Province, Yajiang County (30°03′N, 101°65′E), 8.ix.2005, Fuming Shi.

Host plant. Unknown.

Distribution. China: Sichuan.

Remarks. The new species resembles Chinaocerus bispinatus externally, but differs in having the body slightly reddish brown, the pronotum with a trapeziform brownish stripe, and the aedeagus shaft nearly straight, with two pairs of elongate apical processes.
