Description

Female

Unknown.

Male

BODY LENGTH. 11 mm.

HEAD. Integument black, antenna dark brown ventrally. Face with grayish white to white hairs ( Fig. 55B ), with black hairs intermixed along inner eye margins and on vertex. Clypeus with very dense, small punctation (<0.2 pd). Malar area narrow, length about ½ width of mandibular base. Facial fovea narrow, maximum width about ½ antennal diameter.

MESOSMA. Integument black, legs brown, tarsi reddish to yellowish brown ( Fig 55A ). Scutum with long grayish to yellowish white hairs, intermixed with dark brown hairs. Mesosomal sides and legs grayish white, with some brown hairs intermixed on mesepisternum. Disc of scutum with medium-sized, scattered punctures (0.5–1 pd), integument glabrous, surrounded by dense, small (<0.2 pd) punctation ( Fig. 55C ). Scutellum and metanotum long, yellowish white, with dark brown hairs intermixed on scutellum. Upper sloping part of propodeal triangle with short, longitudinal carinae anteriorly, scabriculous posteriorly. Vertical part superficially shagreened and shiny, with some weakly developed more or less transverse carinae. Hind basitarsus modified, broadened apically, curved ( Fig. 55F ), slightly convex and with prominent long reddish bristles on apical dorsal edge. Inner side of hind basitarsus only hairy on ⅔ dorsally, ventrally some scattered bristles. Tarsal segment 2 heart shaped, dorsal side is strongly broadened and rounded ( Fig. 55F ). Mid femora with right-angled edge on basal end, ventrally with long spine and femur slightly swollen.

METASOMA. Integument black, terga narrowly translucent posteriorly and T1–T3 with slight bluish shine. T1 covered with long, erect, grayish white hairs ( Fig. 55D ). Disc of T2 with shorter erect hairs with same color as on T1. Discs of T3–T6 with erect blackish hairs. T1–T6 with relatively broad posterior tergal hair bands ( Fig. 55E ), on T1 and T6 narrower. Discs of T1 and T2 with fine, dense punctation (0.5–1 pd), punctures becoming slightly finer on posterior tergal depression, interspaces glabrous ( Fig. 55D ). S2–S5 with dense, relatively short fringes, laterally longer than medially. Disc of S2 covered with erect white hairs. On S5 with two elevations laterally and on S6 more medially and anterio-laterally with elongate brush of dense, short, red bristles. S7 ( Fig. 55G ) and gonostylus ( Fig. 55H ) as illustrated.
