Redescription:

Head: Dark red-brown to black, dull red-gold pruinose, extensively black setose. Antenna: Dark red-brown. Segmental ratios: 1:1.0:4.4:3.0 (scape, pedicel, postpedicel, style). Scape and pedicel of similar development, black setose. Postpedicel circular in cross-section, parallel sided, tapering distally. Style of similar diameter to distal end of postpedicel, equipped with long black setae projecting from all surfaces. Face, frons and vertex dull red-gold pruinose, mystax black, ocellar macrosetae black. Occiput dull red-gold pruinose except for two large subtriangular apruinose areas between dorsal eye margin and cervical region (see Fig. 2E), black setose dorsally, white ventrally. Face to head width ratio in anterior view 1:3.7 (face narrower than one eye). Proboscis dark red-brown, straight, pale yellowish setose. Palpi small, 2-segmented, yellow and brown setose.

Thorax: Dark red-brown to black, extensively red-gold and silver pruinose, black and pale yellow setose. Mesonotum: Extensively pruinose with following apruinose areas: postpronotal lobes, elongate lateral area anterior to transverse suture, large posterolateral area involving much of postalar lobe, pair short, narrow strips falling far short of anterior and posterior margins. 2 black npl (other macrosetae weakly developed), general setae longish dark red-brown. Scutellum dark red-brown, entirely apruinose, fine dark red-brown setose (apical macrosetae poorly differentiated). Pleura fairly uniformly silver pruinose. Katatergal setae black mostly dark red-brown with few yellow (♂) or yellow with few dark red-brown (♀). Legs: Entirely dark red-brown to blackish. Coxae silver pruinose, whitish setose. Trochanters pale yellow-white setose. Femora mixed dark red-brown and pale yellowish setose. Tibiae and tarsi mostly dark red-brown setose. Wings: 4.8 × 1.5 mm (holotype). Veins dark red-brown. Membrane transparent, weakly yellow-brown stained, entirely lacking microtrichia.

Abdomen:Terga dark red-brown, largely apruinose except for silver pruinose anterolateral margins, mixed white and dark red-brown setose. Sterna dark red-brown, extensively dull silver pruinose except for large lateral and posterior areas, white setose. ♂ and ♀ terminalia dark red-brown.
