ABSTRACT

Planicapritermes Emerson, 1949 is a South American termite genus with two nominal species: Planicapritermes planiceps (Emerson, 1925) and Planicapritermes longilabrum Constantino, 1998. The soldiers of this genus are characterized by strongly asymmetrical mandibles. Planicapritermes planiceps was described from soldiers and workers, and P. longilabrum only from soldiers. Here we describe and illustrate workers of P. longilabrum based on specimens collected in Rondônia state, Brazil. We also present a comparison between workers and soldiers of P. planiceps and P. longilabrum, and describe the nest of P. planiceps.
