Remarks

Despite its colour pattern with bands and spots, this species fits well with the diagnosis of Mycolybas Crotch, 1876 proposed by Lopes (2006), and the general features mentioned by Pecci-Maddalena et al. (2021b) for this genus. The following combination of characters quickly removes “ antesignatus ” from Mycotretus and places it in Mycolybas : absence of mesocoxal lines on the metaventrite (not verified in Mycotretus ), mental plate pentagonal, humeri protuberant and the general morphology of the flagellar head of male genitalia, similar to that of other Mycolybas species (see Lopes 2006).
