Description. Similar to Sennertia argentina, see differences in the key to species of Sennertia.
(Neoxylocopa) frontalis (Olivier, 1789) (type host)
Xylocopa (Neoxylocopa) fimbriata Fabricius, 1804
Distribution (Show map). Trinidad and Tobago (type locality), Brazil, Venezuela.
Notes. Fain (1981a) synonymized this species with Sennertia argentina. We found distinct differences between S. argentina and S. donaldi (see key) and, therefore, consider the latter as a valid species.
