Male redescription. Structure: Front with an elevated tubercle present in the middle between the supra-antennal plates; Propodeum with strong transverse striae dorsally and with long pubescence; forecoxae subtriangular, flattened, with the outer lateral margin enlarged and covered with long and thick pubescence. Inner margin raised anteriorly; hindfemoral-hindtibial joint lobes both slightly thickened posteriorly; epipygium strongly and deeply punctuated forming raised rugosities, a central longitudinal one almost reaching the apical margin;

Genital capsule: Basal ring with its dorsal surface longer on its apical margin. Slightly depressed sublaterally before the apex, with a longitudinal line medially in dorsal view; gonocoxite broad, with its basal region almost wider than the basal ring. With about half the gonostylus extension. The apex contiguous, with soft teeth sublaterally; aedeagus lamellate, with about 3/4 the gonostylus extension. Apex curved ventrally, with a small rounded lobe apically and curved dorsally; gonostylus slender, slightly tapering towards the slightly rounded apex. Strongly curved ventrally, with the medial region strongly constricted. With golden pubescence on the half apical region margins.

Coloration. Body predominantly black, with a few yellow markings. Mandibles except for the apex and base. Clypeus black with a short fascia centrally, before the apical margin. Large fasciae on the anterior margin of the pronotum, not fully interrupted in the middle. The tegulae and a small rounded spot on the mesopleuron anteriorly. Scutellum with large tridentate spot medially and the metanotum almost entirely. Yellow spots on the inner surface of the fore and midfemur. transverse fasciae on tergites I–VI, broadly interrupted on last one, slightly or not interrupted on the others. Small rounded spots on the sternites II–V laterally.

Female: unknown.

Distribution. The species is recorded from South of Brazil (MfN) and Montevideo, in the humid subtropical coast of Uruguay (NHM– UK).
