( Figs. 5–9 View Figure 5 View Figures 6–9 )

DIAGNOSIS: This species is distinguished by the black integument, the extensive white pubescence, and the strongly produced axillae. The ocellocular area has a polished band from the lateral ocellus to the eye margin; the band is impunctate or with a few scattered punctures ( Fig. 6 View Figures 6–9 ).

DESCRIPTION: Female holotype. Length, 17.0 mm; length of forewing, 14.0 mm. Color. Integument black, except reddish pedicel and first flagellomere. Wings deeply infuscate, with dark brown to black veins and pterostigma. Pubescence. White, short and sparse on most of body. Dense patches of white pubescence restricted to outer side of antennal socket, dorsal surface of pronotal collar, medially on metanotum, apex of mid coxa, and lateral and dorsal surfaces of hind coxa. Propodeum with hairs longer and denser on posterolateral angles, but not hiding integument. Scutum with abundant semierect hairs 0.25–0.45× MOD (these hairs simple or with one or two short basal branches), and erect, simple, sparse hairs 0.5–0.7× MOD. Sculpture. Frons and vertex densely punctate, but ocellocular area with polished, impunctate band from lateral ocellus to eye. Longitudinal median carina of clypeus strong, reaching apical margin of clypeus. Scutum with small punctures (diameter 40-60 µ), separated by irregular polished interspaces 0.2–0.9× PD. Mesopleuron with similar punctation. Punctures on metasomal terga smaller, on disc of T2 25–35 µ in diameter, separated by 0.2–1.0× PD. Structure. Labrum 1.82× as broad as long, with pair of small apical denticles separated by shallow emargination. Clypeus moderately protuberant, in lateral view protruding in front of eyes by less than half of eye width (0.4×). Axilla with lateral margin sinuous, with apex bent mesad; produced pointed apex compressed, dorsally keeled, in lateral view digitiform; proportions between lengths of lateral margin, mesal margin, and free portion of mesal margin 1.03:1:0.43; lateral margin 0.71× scutellar width. Scutellum bigibbous; gibbae with conical, polished summits, directed backwards. Hind basitarsus shorter than intertegular span (0.83×).

Male. Length, 14.0–16.0 mm; length of forewing, 13.5–14.4 mm. Color, pubescence and punctation similar to those of female. Length of free portion of mesal margin of axilla in studied males 0.45–0.50× total length of mesal margin. Hind basitarsus slender, 0.76–0.80× intertegular span. Pygidial plate parallel-sided with truncate apex. Sterna without apical fringes of hairs.

ETYMOLOGY: The specific name refers to the type locality.
