Coria with a circular yellow spot near to the posterior margin ( Fig. 20 , A); urosternite III tubercle yellow or orange, from apex to the posterior margin of the urosternite; two pairs of yellow abdominal spots, the first pair lateral in urosternites VI and VII, and the second pair mesial in urosternite VII; vesicular area of female genitalia twice longer than the proximal part of the ductus receptaculi. Redescription BODY: General color ranging from brown to iridescent purple; some specimens with yellow spots, callous or not, on the head, pronotum and scutellum. HEAD: Mandibular plates equal to or slightly surpassing clypeus, anteriorly rounded, separated at apex; head length anterior to the eyes equal to 2/3 of the total length of the head ( Fig. 20 , D); labium almost reaching the metasternum; proportion of labiomeres: I<II>III<IV; proportion of antennomeres: I<II<III ≅ IV ≅ V. THORAX: Coria longer than scutellum, not reaching the posterior margin of the connexival segment VI, uniformly punctured; membrane dark and surpassing posteriorly the abdomen; metapleural evaporatoria surpassing posteriorly the anterior limit of coxae; peritreme disc-shaped, surpassing half the pleural width; apex of peritreme rounded, posterior margin strongly arched, convex, anterior margin almost straight ( Fig. 20 , E); profemora with rudimentary ante-apical spine; foretibial length on average 3.5x larger than the width of the tibial dorsal expansion ( Fig. 20 , F). ABDOMEN: Posterior angles of urosternites III to VII ending in minute spine ( Fig. 20 , B). FIGURE 23. Heteroscelis denieri Pirán, 1961 , male holotype. A, dorsal; B, labels (MLPA).
