Abstract

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.

Highlights

  • Planicapritermes Emerson, 1949 is a South American termite genus with two nominal species: Planicapritermes planiceps (Emerson, 1925) and Planicapritermes longilabrum Constantino, 1998

  • Some genera of Termitinae are characterized by having soldiers with asymmetrical mandibles, such as Neocapritermes Holmgren and Planicapritermes Emerson (Constantino 1999)

  • Planicapritermes was described by Emerson to accommodate a single South American species, P. planiceps, previously included in the subgenus Neocapritermes of the genus Capritermes (Constantino 1998)

Planicapritermes was described by Emerson (in Snyder 1949) to accommodate a single South American species, P. planiceps, previously included in the subgenus Neocapritermes of the genus Capritermes (Constantino 1998).
