A new genus and species of the bee tribe Augochlorini (Halictinae) is described and figured from northern Venezuela. Trichommation osculans Engel, new genus and species, is a member of the Megaloptidia-group of genera as evidenced by the narrow and elongate mouthparts and sharply pointed galeal apex. The genus is most similar to Megommation Moure and Megaloptidia Cockerell, particularly in the enlarged ocelli present only in these genera among those in the group. Aside from intermingling traits of both of these genera, Trichommation is further distinct from both owing to the presence of ocular setae, a pectinate inner metatibial spur, and basal rugae on the basal area of the propodeum. Emendations to the key to genera of the Megaloptidia group are provided to allow for the identification of Trichommation.
