Entries below with an asterix are listed in publications by J J Vermeullen and so are more likely correct than ones without. Species with a question mark in front, seem to me to not conform and so please use with caution.

According to Vermeullen 2014 there are too many species within this section as to which ones do not belong, I await more information
