Comments. Specimens of Poriptus filius are known only from Argentina, in the Chacoan and Parana subregions sensu Morrone (2006). The species can be easily distinguished from P. l u c t a n s and P. tobago sp. nov. by the antennal segment III surpassing apex of head and the humeri laterally directed.
