Discussion.

In the forewings of Priasthenopus gilliesi , vein MP1 is basally free except on Bolivian males where this vein tends to fuse with MP2, although not completely. This last arrangement of the MP sector is also present in Campsurus paraquarius Navas (1920) and, also coincident, are the length and arrangement of the two imv (intercalary marginal veinlets) figured by Navás, the relatively short ICu veins and the vein AA basally curved to CuP; also the small size of the male described by Navás coincide with Priasthenopus size range. Navás described the color of legs without saying that middle and hind legs are reduced (as Campsurus ), so probably they were present and complete as in all Asthenopodinae. Finally Navás stated that the pronotum is wider than long (transverse), feature also present in Priasthenopus and related genera ( Asthenopus , Povilla ) but not in Campsurus males. Other species of Neotropical Asthenopodinae show shorter intercalary marginal veins ( Asthenopus s.s.) or longer ICu veins ( Asthenopodes ). Lestage (1923) noted the similiraty of Navás species with the genus Asthenopus and Kluge (2004) treated this species in Asthenopus because of the arrangement of veins in the Cu sector of FW. We here coincide with these authors and because of the bad original description by Navás, and the apparent loss of type material, we treat the name paraquarius ( Navás 1920) as a NOMEN NUDUM.
