Remarks

Mycotretus minutus resembles M. pygmaeus ( Fig. 35C View Fig ) in body shape and morphology of male genitalia. In the absence of a larger series of named specimens for comparison, we prefer not to synonymize these species. Duponchel (1825) stated that M. minutus “(…) fait partie de la collection de M. le comte Dejean, qui l’a nommée minutus ”. In the Brême collection (MRSN), there is one specimen labeled “D. Gysselen”, a name that sometimes appears in Dejean’s catalogue (although not close to the name “ minutus ”). We are still in doubt whether that specimen would be the primary type or not; therefore, we prefer not to assign type status to it.
