TYPE LOCALITY. — Brazil, State of Goiás, municipality of Pirenópolis.

ETYMOLOGY. — From Latin, “fusca” means “dark”. This species is darker than the other species of the genus.

TYPE MATERIAL. — Holotype. Brazil • ♂; GO, 17 km E from Pirenópolis ; 15°48’11”S, 48°51’94”W; 12-17.X.1997; 1349 m; A. Mesa and P. Garcia leg.; rupestrian field; genitalia removed and kept with the specimen, preserved in ethanol 80%; Alejo Mesa Collection; MZUSP004864; MZSP.

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. Female genitalia: anterior 2/3 wider than posterior third in dorsal and ventral views; dorsal face posterior third whitish; ventral face with a whitish macula.
