Allotype. Brazil • ♀; same data as for holotype; copulatory papilla dissected and kept with the specimen; preserved in ethanol 80%; MZSP.

Paratypes. Brazil • 1 ♂; same data as for holotype; preserved in ethanol 80%; MZUSP004857, MZSP. 2 ♀; same data as for holotype; preserved in ethanol 80%; MZUSP004866, MZUSP004855; MZSP .

DIAGNOSIS. — General coloration medium to dark brown. Male: cephalic pair of projections elliptical in the median line of metanotum, large, concave anteriorly; caudal pair of projections, median, small, apex pointed; a pair of clusters of bristles pointing to caudal margin, one single cluster, larger, pointing to cephalic margin. FWs: connection region of anal veins strongly sclerotized. Male genitalia: MLophi elongated, apex pointed; EctF very sclerotized; anterior portion concave, forming lateral lobes with spines, posterior portion very thin.
