Pubescence: Head white hairs and scattered dark hairs on frons and vertex, genae white, scutum, scutellum and metanotum light brown with scattered dark brown hairs; mesosoma laterally and ventrally with pale to white, fore leg with long pale hair on outer surface; fore leg inner surfaces of tibia and tarsus with short orange-brown hair; mid femur anterior and posterior surfaces pale; mid tibia pale; mid metatarsus pale, last segments orange, mid tarsus inner surface orange with two dark brown streaks, hind leg outer surface of femur, tibia and metatarsus pale, hind leg inner surface black; metasomal terga with pale ochre adpressed hairs intermixed with scattered erect black hairs on T1-T3 and white erect hairs on T4-T6, T2 anteriorly without dark hairs, T7 short white pubescence, S1-S5 with pale apical fringes laterally only; S3 with open row of simple setae on premarginal line, S4 apicomedial area with rectangular patch of pale apically directed bristles circa 1/3 of sternal width Fig. 6C ); S5 with dark branched hairs on marginal zone around emargination, flanked with pale hairs on disc, S6 with smooth marginal zone and sparse to openly placed branched hairs.

Colouration: Integument of head black apart from: scape yellow below, labrum yellow with brown dots in dorsolateral corners, clypeus orange-yellow, supraclypeal area orange-yellow, paraclypeal area brown, mandible yellow with dark brown tip, proboscis orange; mesosoma black, metasoma brown with orange translucent marginal zones; legs orange apart from coxae, trochanters and basal half of femur brown.

Female allotype (WAM 5471): Body length 14 mm, forewing length 10 mm, head width 5.6 mm.

Structure: Inner orbits of eyes slightly diverging above; head wider than long; clypeal protuberance in profile 0.67 × eye width; mandible with weak subapical tooth; F1 equal to combined length of next 3.3 flagellomeres; F1 0.93 × as long as scape; F2 0.75 × as long as F3; F3-F10 circa as long as wide; last flagellomere 0.57 × length of F1; marginal cell length 0.42 × the length of costal vein R; cu-v of hind wing 0.86 × length of second abscissa of M+Cu; S6 with broadly rounded area raised posteriorly (Fig. 6L ).

Pubescence: Head white with scattered dark hairs on frons and vertex; genae white; scutum, scutellum and metanotum light ochre with scattered dark brown hairs; mesosoma laterally and ventrally with light ochre hairs under the wing bases, remaining hairs white; fore leg with pale hair on inner and outer surface; mid and hind legs whitish on outer surfaces, black-brown on inner surfaces, including black hairs on hind trochanters, mid tibia, mid metatarsus and mid tarsus; metasomal terga with pale ochre adpressed hairs intermixed with scattered erect black hairs on T1-T3 and white erect hairs on T4-T6; T2 anteriorly without dark hairs; T5 with brown prepygidial fimbria, T6 with strong orange-brown hairs flanking the pygidial plate; S1-S5 with ochre erect hairs on posterior margins.

Colouration: Integument of head black, apart from scape yellow below; flagellum orange below, brown above; labrum pale yellow with translucent dots in dorsolateral corners; clypeus pale yellow with two vague subparallel brown linear marks; supraclypeal area with small pale yellow mark; paraclypeal area with small pale yellow mark in ventral corner; mandible pale yellow at base, black at tip; proboscis orange-brown; mesosoma black; metasoma brown with orange transparent marginal zones; legs orange apart from coxae, trochanters and basal half of femur brown.
