Face moderately narrowed ventrally, finely rugose-punctate, minimal width 0.63x eye length and 0.95x frontal width. Clypeus raised apically, in profile nose-like expanded. Malar space length 0.5x width of mandibular bases. Genal carinae strongly bent outwards and reaching mandibular bases in an angle of 90°, genae concave ventrally. Hypostomal carinae moderately elevated.

Mesopleural discs rugose, with superficial punctures, dorsal impressions and specula partly with coarse striation. Prepectal carina not elevated and not developed on the transversal part. Metapleura rugose; coxal carinae not developed. Propodeum with complete but fine carinae; area superomedia very wide (2x length); area petiolaris distinctly and widely impressed, with coarse transversal rugae. Hind femora length 5.0- 5.2x width, length of inner spurs of hind tibiae 0.65x hind metatarsi length. Hind claws pectinate. Areolets stalked, 2 nd recurrent veins distal to the middle; nervuli postfurcal; postnervuli intercepted in middle; external angles of discoidal cells acute (70-80°); nervelli of hind wing somewhat reclivous, often intercepted in apical 0.7. 2 nd tergite length (1.25)-1.4-1.5x-(1.9x) width, 3 rd tergite length 0.7-0.8x (-1.0x) width, distance of thyridia from basal margin 1.0-1.5x their length.

Colour: Black. Palps brownish-yellow. Mandibles except teeth and tegulae blackish, tegulae sometimes reddish-brown. Subapical band of 2 nd tergite, 3 rd tergite and usually 4 th tergite completely and sometimes 5 th tergite basally red. All coxae and trochanters black; femora blackish, fore femora apically reddish; fore tibiae and tarsi reddish, yellow externally; middle and hind tibiae brownish to blackish, with cream yellow basal rings; middle and hind tarsi except yellowish bases of metatarsi dark brown. Pterostigmata pale to dark brown.
