Remarks

1) Mycotretus mutabilis is a new junior synonym of M. maculatus Olivier, 1792 ( Fig. 39E, see below). 2) Under the description of M. mutabilis, Crotch (1876: 438) stated the following: “(…) In one specimen ( M. tricinctus ), which may be distinct, there is a third supplementary subapical fascia. Sides of the metasternum very sparingly punctate”. Although Crotch had suggested the name “ M. tricinctus ”, he did not provide a description for this species and that name has never been published anywhere, being therefore a nomen nudum. The specimen labelled as “ M. tricinctus ” in UMZC is morphologically similar to those from the type series of M. mutabilis with a few differences in the colour pattern that may be an infraspecific variation. Based on Crotch’s description and our examination, the specimen labelled as “ M. tricinctus ” is here considered a paralectotype of M. mutabilis , but we included a question mark on its label.
