Temples narrow, roundly narrowed behind eyes; head 2.25x wider than long. Distance of lateral ocelli to eyes 0.9x and between them 1.9x their diameter. Face slightly narrowed ventrally, finely rugosepunctate, minimal width 0.95x frontal width and 0.7x eye length. Malar space length 0.5x width of mandibular bases. Genal carinae strongly bent outwards ventrally, reaching mandibular bases in an angle of c.90°; genae concave ventrally. Hypostomal carinae slightly elevated.

Sides of pronotum with strong striation, dorsally granulate. Mesopleural discs ± rugulose-punctate; specula granulate; dorsal impressions strongly striate, striae reaching anterior margin of mesopleura. Prepectal carina lamelliform elevated ventrally, narrow on mesopleural parts, not developed on transversal parts. Propodeum rugose, without distinct carinae, with moderate central longitudinal impression covered with some transversal rugae. Hind femora length 4.7-5.0x width; inner spurs of hind tibiae 0.7x as long as hind metatarsi. Hind claws pectinate. Areolets stalked, 2 nd recurrent veins in or distal of middle; nervuli postfurcal; postnervuli intercepted before middle, external angles of discoidal cells acute (70-80°); nervelli of hind wings more or less interstitial, not distinctly intercepted. 2 nd tergite length 1.8-2.8x width; thyridia roundish, distance to basal margins of tergite 1x their length; 3 rd tergite length 1.1-1.5x width.

Colour: Black including flagella, tegulae and mandibles. Palps reddish-yellow. 2 nd tergite subapically or apically, 3 rd tergite except basal black spot, and following tergites completely reddish. Legs blackish; fore femora, tibiae and tarsi yellowish-red; middle and hind femora narrowly yellow at bases; all tibiae with basal ivory spots, middle tibae ivory externo-medially; hind tarsi except ivory bases of metatarsi blackish. Pterostigmata brown.
