Temples narrow, strongly narrowed behind eyes; head 2.4x wider than long. Distance of lateral ocelli to eyes 0.65-0.85x and between them 1.2-1.4x their diameter. Face moderately narrowed ventrally, finely rugosepunctate, minimal width 0.60x eye length. Malar space length 0.5x width of mandibular bases. Genal carinae moderately bent outwards ventrally, reaching hypostomal carinae shortly before mandibular bases in an acute angle. Hypostomal carinae slightly elevated.

Mesopleural discs granulate, with superficial punctures; specula granulate, matte; dorsal impressions strongly striate. Prepectal carina not elevated and not developed on the transversal parts. Metapleura finely rugose; coxal carinae ± distinct.

Hind femora length 4.6x width; length of inner spurs of hind tibiae 0.65x hind metatarsus length. Areolets sessile; nervuli postfurcal; postnervuli intercepted below middle; external angles of discoidal cells acute (80°); nervelli of hind wing interstitial, more or less intercepted. 2 nd tergite length 1.7x width, 3 rd tergite length 0.9x width.

Colour: Black. Palps, mandibles except teeth and tegulae yellowish. Scapes partly reddish; flagella black.

All coxae and hind trochanters black; fore and middle trochanters and trochantelli yellowish, sometimes black, hind trochantellus red or black; legs otherwise reddish; hind tibiae yellow basally, slightly darkened subbasally and in apical 0.3; hind tarsi except pale bases of metatarsi dark brownish.
