5. Mycotretus rhodosomus + M. reticulatus + M. flavomarginatus

(Fig. 1S, T, U; character 15:1 and Fig. 5I, J) ‘anterior borders of flagellum head with a ‘head-piece’ structure’. This feature was observed in other Mycotretus, such as M. pecari Lacordaire, 1842, M. psittacus Lacordaire, 1842 and M. tricolor Crotch, 1876 (not included here). All of these species are larger in body size than most Mycotretus and the larger males have arched metatibiae.
