Subgenus Sinomophorus Wang, Alonso-Zarazaga, Ren & Zhang, 2011

Type species. Omophorus rongshu Wang, Alonso-Zarazaga, Ren & Zhang, 2011: 44 .

Diagnosis (modified based on Wang et al. (2011)). Distinguished from nominal subgenus by the absence of tubercle on pronotal surface; bifid vestiture of the venter; the obtuse humeral angle; extremely small extent of sclerotization in the endophallus; absence of styli in the ovipositor and the absence of a spiculum ventrale on female sternite VIII. It can be separated from the subgenus Pangomophorus Voss, 1960 by the bifid vestiture of the venter; the obtuse humeral angle; and the presence of a metatibial uncus. Several diagnostic characters, including longer antennal club; elongate subtrapezoidal scutellum and smaller subhumeral calli, proposed in Wang et al. (2011) are considered invalid for a new subgeneric delimitation on the basis of the comparison between O. (S.) rongshu and O. (S.) wallacei (see details in discussion).
