Pediobius alcaeus species-group

Diagnosis. Notauli complete with inner margins step-like, and notaular depressions distinct and deep (e.g., Fig. 1 a). Propodeum with submedian carinae anteriorly fused and forming a crest against the protruding apex of dorsellum, but posteriorly diverging straight backwards (e.g., Fig. 1 a). Female Gt1 short, not reaching mid-length of gaster (e.g., Fig. 1 a).

Species included. Bouček (1965a) stated that P. termerus (Walker) and P. coxalis Bouček seemed to be allied with P. alcaeus (Walker) . Gumovsky (2003) included these three species along with P. fastigatus Kamijo and P. ikedai Gumovsky in the alcaeus -group. Here, we add other three newly described species, P. bisulcatus , P. elongatus and P. petiolapilus to this species group.
