Diagnosis

(based on species covered in this paper; Periplaneta s.s.). Sexual dimorphism indistinct or distinct. Pronotum subelliptical in male, subelliptical or campaniform in female. Tegmina and wings well developed in male, developed or reduced in female. Legs slightly slender. Abdomen with the first tergite unspecialized in male. Hind margin of supra-anal plate hyaline and concave in the middle; cerci long, apically tapering. Hind margin of subgenital plate slightly convex. Genitalia of male: L1 weakly sclerotized with pubescence; hind margin of L4C nearly truncated; the caudal part of L2 with a long spine toward right; L3 with hlap weakly developed; the basal part of L4G constrict. R1H with two long spines at apex; the caudal part of R1G with a long and curved spine toward right. Genitalia of female: Anterior arch (a.a.) with two symmetrical foot-shaped projections; spermathecal plate (sp.pl) nearly crescent-shaped; the enlarged part of spermatheca (sp.) curved, subelliptical or irregular; basivalvulae (bsv.) subelliptical; laterosternal shelf (ltst.sh.) with postero-lateral angle extended towards outer margin.
