Hypostomal carinae not elevated.

Mesopleural discs granulate and distinctly punctate, somewhat shining; specula granulate, matte; dorsal impressions with rows of granulae or fine striae. Prepectal carina not elevated and absent on the transversal parts. Metapleura finely rugose; coxal carinae not developed. Propodeum with basal carinae (area basalis+ basal part of area superomedia); area superomedia slightly longer than wide; area petiolaris slightly impressed, with fine irregular rugae. Hind femora length 4.5-5.4x width; length of inner spurs of hind tibiae 0.7x hind metatarsus length. Areolets stalked, 2 nd recurrent veins proximal or distal of the middle; nervuli postfurcal; postnervuli intercepted below its middle; external angle of discoidal cells 90°; nervelli of hind wing reclivous, intercepted in apical 0.4-0.6. 2 nd tergite length 1.2-1.5x width; thyridia roundish, distance to basal margins 0.5-1.0x their length; 3 rd tergite length 0.65-0.85x width.

Colour: Black. Palps yellow-red to brownish. Mandibles except reddish teeth and tegulae brown to blackish. Postpetiolus usually red apically, 2 nd tergite red in the apical 0.5-0.7, 3 rd tergite completely red, 4 th tergite completely red or with black apical margin, sometimes 5 th tergite red basally. All coxae and trochanters black; trochantelli reddish; legs otherwise red, (middle) and hind femora narrowly infuscate at apex; hind tibiae ± infuscate basally and/or apically; hind tarsi except narrow yellow basal spots of metatarsi brown to black. Pterostigmata brown.

♂: Flagella with 33-35 segments, all flagellomeres longer than wide. Temples moderately narrowed behind eyes. Hind femora length 4.6-5.3x width. 2 nd tergite length 1.05-1.3x width, 3 rd tergite length 0.6-0.8x width. Hind femora completely red or infuscate apically.
