Pecci-Maddalena, Italo Salvatore De Castro, Lopes-Andrade, Cristiano & Skelley, Paul, 2020, The metendosternite and penile flagellum: two unexplored character systems of pleasing fungus beetles (Coleoptera: Erotylidae), Zoological Journal of the Linnean Society 193, pp. 953-972 : 969

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.
