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.
