Pérez (1895) original description

115. P. platymerus . ­ femelle. Diffère du Banksianus par la pubescence fauve, plus pâle à la brosse, rousse au milieu de la frange anale; les dépressions très décolorées, beaucoup moins surbaissées et plus étroites; la ponctuation très fine et très serrée, nullement rugueuse sur les disques; le triangle très court, faiblement chagriné au milieu; les ailes un peu jaunes, l'écaille testacée.

Mâle. Plus robuste que le Banksianus ; villosité plus longue sur la tête; ponctuation de l'abdomen peu sensible; dépressions beaucoup moins surbaissées, plus larges, brunes; fémurs moyens et postérieurs dilatés, aplatis; ces derniers presque anguleux au milieu, leurs trochanters anguleux au bout; prototarse postérieur aussi long que les quatre article suivants, très arqué; poils des tibias et tarses d'une fauve doré; funicule grêle et noueux.

Diagnosis. No female paralectotype. Male. Large black species. Cuticle smooth, weakly sculptured and strongly shiny. Head large. Labral lamella apically round, indented. Pilosity brownish on head and thorax, blonde on legs. Genital structures shape similar to those of Panurgus cephalotes and Panurgus maroccanus .

Head: Face shorter than wide (l/w = 6/8.5). Cuticle sparsely punctured; clypeal punctuation finer and denser than on face. Labral lamella deeply round, indented at apex. Mouthparts as in other Panurgus s.str. species. Antennae thin, entirely black. Head pilosity poorly conserved on lectotype, apparently blonde. Mesosoma: Pronotum black, finely and sparsely sculptured, very smooth. Mesonotum smooth, shiny, finely and very sparsely punctured. Mesopleura black, smooth and shiny, regularly punctured. Scutellum and metanotum sculptured as mesonotum. Propodeum superficially finely punctured, weakly shiny. Thoracic pilosity dark. Legs dark, brownish black, terminal tarsal cuticle a bit lighter. Leg pilosity blonde. Wings light brownish. Metasoma: Terga with proximal parts black with few fine punctures. Terga with apical depressions brownish, unpunctured. Metasoma nearly bare. St6 with two distal tufts of long black hairs. St7 spandrel like, ending in a large indented apical process bearing a strong carina. St8 simple, triangularly enlarged at the apex. Genital structures ( Fig. 1 ). Gonocoxites simple, sculptured and mat, apically truncated; inner margin longer, angular at apices. Penis valves little enlarged between proximal 1/3 and apices. Gonostylus strongly curved, with a long tapered median process and a dense tuft of long strong black hairs.
