Comments: Podisus dufouri Bergroth was synonymized with Podisus rostralis ( Stål, 1860) by Thomas (1992), based on an illustration of the male genitalia provided by Hildebrand (1987). Indeed, the parameres of both species are very similar, presenting two long branches distinctly surpassing the dorsal rim; the internal branch is acute, tapering towards the apex, and the external branch presents two distinct angles. However, the external morphology of P. dufouri presents distinct features, described below, compared to P. rostralis , enabling their differentiation. Thus, we propose the revalidation of Podisus dufouri .

Podisus dufouri has pale calloused areas in the anterior angles and apex of the scutellum, and in the disc of pronotum, giving a marble aspect to the species dorsum. The humeral angles are acute and present a posterior protuberance. On the mesopleura, the area posterior to the peritreme is dark brown. All these features are absent in P.rostralis . Additionally, the pygophore of P. dufouri presents the posterior angles laterally expanded and developed, instead of short and rounded as in P.rostralis .
