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

1. Mycotretus trifasciatus + M. floriger

( Fig. 1G, Q ; character 17:1 and Fig. 5L ). ‘virga with a median membranous portion containing a slight sinuosity’. This feature was observed in other Mycotretus , for instance, M.chilensis (Crotch, 1876) ( Pecci-Maddalena & Lopes-Andrade, 2017) and M.episcaphoides Crotch, 1876 (not included in this study).
