A new species of Potamocoris (Heteroptera: Potamocoridae) from Belize, and synonymy of the genus Coleopterocoris

A new species of Potamocoridae, Potamocoris isbiru, is described from Belize. This taxon is easily recognized by the thick fringes of gold setae on the lateral margins of the head, pronotum and basal hemelytra. This new species also exhibits both fully macropterous and coleopteriform wing morphologies, thereby encompassing the character states previously used to discriminate the genus Potamocoris Hungerford from the genus Coleopterocoris Hungerford. On the basis of this intraspecific wing polymorphism, we conclude that Coleopterocoris is merely the coleopteriform morph of Potamocoris, and synonymize it under the latter genus. Figures of key morphological characters are provided for P. isbiru, accompanied by a photograph of typical habitat in which the species occurs, and a distribution map.
