Key to the genera of Cryptolaryngini Van Schalkwyk, 1966

1. Scales on elytra subcircular, at most slightly longer than wide, appressed and imbricate (concealing integument). Eyes more lateral, interocular distance twice width of epifrons. Tarsi subcylindrical. Male genitalia with spiculum gastrale symmetrical. Western and Central Asia ................................. ................................................................................................................. Perieges Schoenherr, 1842

– Scales on elytra generally elongate, at least 1.5 × as long as wide, dense to tessellate, if shorter then not concealing integument ( Fig. 1B ). Eyes more directed anteriad, interocular distance less than twice width of epifrons ( Fig. 4A–X ). Tarsi flattened. Male genitalia with spiculum gastrale asymmetrical ( Fig. 2 ). Southern Africa ............................................................................................ 2

2. Body in male globular or moderately elongate, elytral W:L ratio 0.85–1.1. Pronotum widest at or just behind its midlength.Metatarsi with segment 2 short, at most as long as wide.Body in male more globular and shorter than in female.Parameroid plate of tegmen apically divided into two parameroid lobes, bearing erect setae on apical and/or subapical margins ( Fig. 2A–W ) .......... Cryptolarynx Van Schalkwyk, 1966

– Body in male elongate, elytral W:L ratio 0.7. Pronotum widest in apical third of length. Metatarsi with segment 2 long, at least 1.5× as long as wide ( Fig. 8F ). Body in male more elongate than in female. Parameroid plate of tegmen apically undivided, its margin devoid of setae ( Fig. 2X ) ......... ....................................................................................................
