Key to the species of Paravelia View in CoL recorded from Brazil

Specimens of part of these species were not examined, and only the characters mentioned in the original descriptions have been considered, which makes the key somewhat preliminary. However, because literature on Paravelia is scattered over several, sometimes rather old, small papers dealing with descriptions of one or a few species only, a comprehensive key to the genus is urgently needed.
