Body length: 8–11 mm . Male frontal calli scarcely developed and raised over the head, with a frontal area well visible between them ( Fig. 5F ). Male antennae from scarcely modified: antennomere I with a dorsal keel variously shaped and developed, in few cases with a pointed and curved expansion on external side; II always simple and subcylindrical; III enlarged and swollen, in some species only scarcely enlarged and with a weak incision on external side; IV enlarged and variously shaped; V–VIII usually simple and cup-like, in few cases antennomeres V–VI ventrally enlarged and flattened; IX variously shaped but always swollen. Male maxillary palpi poorly modified, in C. simplicicornis almost not modified: palpomere I always simple and slender; II–III in two species ( C. dahli and C. bernhaueri ) only weakly enlarged, in C. schaefferi and C. prochaskana distinctly enlarged and flattened; IV variously shaped but usually slender and stick-like. Male protibiae not modified or only slightly swollen dorsally in C. schaefferi and C. prochaskana .
