Redescription. Female ( Figs. 1 and 2 ): Measurements: Approximate body length: 14.8; head width: 4.7; forewing length: 11.3; F1 length: 1.0; F2 length: 0.2; F3 length: 0.3; mandible length: 2.2; mandible basal width: 1.1; thorax width: 6.1. Coloration: Dark brown ( Figs. 1 and 2 ), lighter on legs. Wing membranes light brown with dark brown veins ( Fig. 2 ). Integument and sculpture surface: Integument very shiny, mainly on the metasoma. Clypeus with coarse, dense and relatively uniform punctation, finely areolate on disc. Labrum with finer and denser punctation than the clypeus. Terga with very dense punctation, uniformly distributed on the tergites and with smooth distal margins. T2 with finer and denser punctures than the other terga. Pubescence: Dark brown ( Figs. 1 and 2 ), slightly lighter on the lower edge of the pronotal lobe. Clypeal disc with short and sparse pilosity. Labrum with dense and plumose hairs, with some longer and simple hairs curved downward intermixed. Terga mainly with short and simple pubescence mixed with long and branched hairs on T1 and on the sides of the distal terga. Prepygidial fimbria slightly semicircular, with coarse and mostly simple hairs. Structures: Flabellum elliptic slightly projected forward. Maxillary palpus with four palpomeres (2nd>3rd>1st≥4th). Mandible with five teeth, all with apices acute except the third with apex slightly rounded ( Fig. 1 ). Trimmal angle almost absent. Acetabular carina reaching the base of the third tooth. Clypeus strongly convex (lateral view) ( Fig. 2 ). Labrum semicircular with truncated distal edge and flat disc ( Fig. 1 ). Vertex above the upper ocular tangent ( Fig. 1 ). Inner orbits of compound eyes converging below ( Fig. 1 ). Distance between the lateral ocellus and the eye more than three times the diameter of the median ocellus ( Fig. 1 ). Fore elaiospathe with the secondary anterior comb formed by three giant hairs. Hind elaiospathe with the hairs of the primary anterior comb forming a continuous structure. Primary basitibial plate elliptic, smooth and shiny, with secondary plate lanceolate. Claws with preapical tooth, poorly developed.

Male ( Figs. 3 and 4 ): Measurements: Approximate body length: 14.2; head width: 4.9; forewing length: 12.3; F1 length: 0.9; F2 length: 0.2; F3 length: 0.3; mandible length: 1.7; mandible basal width: 1.0; thorax width: 6.2. Coloration: Integument dark brown, slightly lighter on clypeus, labrum and legs ( Figs. 3 and 4 ). F2 to F11 and apex of F1 orange brown, darker on the ventral surface of the flagellomeres. Wing membranes and veins light brown, without iridescence ( Fig. 4 ). Integument and sculpture surface: Shiny, mainly on the metasoma. Clypeus with coarse, dense and relatively uniform punctation over the entire surface ( Fig. 3 ). Labrum with fine and very dense punctation ( Fig. 3 ). Terga with very dense punctation distributed evenly on each tergite. T2 with denser and finer punctation than that of the other terga. Pubescence: Dark brown, except the anterior half of the mesoscutum and the anterior half of the tegula with yellowish hairs, not reaching the pronotal lobe ( Fig. 4 ). Lateroposterior area, near the tegula with some brown and yellowish hairs intermixed. Lower edge of the pronotal lobe with short yellowish hairs. Terga with mainly short and simple pubescence, with some long and branched hairs mixed on T1 and on the sides of the distal tergites. Distal tarsus of middle leg with a tuft of plumose hairs at the base of the posterior claw. Hind leg with a tuft of plumose hairs at the base of both claws. Structures: Mandible with three teeth ( Fig. 3 ). Apical tooth larger than the other two, subequal in size ( Fig. 3 ). Second tooth closer to the third than to the apical tooth ( Fig. 3 ). Acetabular carina reaching the base of the third tooth ( Fig. 3 ). Trimmal angle poorly developed, almost absent. Clypeal disc convex (lateral view) ( Fig. 4 ). Labrum semicircular ( Fig. 3 ) with slightly concave longitudinally disc. Vertex below the upper ocular tangent ( Fig. 3 ). Inner orbits of compound eyes converging above ( Fig. 3 ). Distance between the lateral ocellus and the eye shorter than the diameter of the median ocellus ( Fig. 3 ). Hind femur widened. Claws with preapical tooth.
