Face slighty narrowed ventrally, finely rugose-punctate, minimal width 0.7x eye length and 0.95x width of frons. Malar space length 0.3x width of mandibular bases. Genal carinae not bent outwards, obsolete ventrally, reaching hypostomal ones close to mandibular bases in acute angle of about 70°. Hypostomal carinae not elevated.

Mesopleural discs granulate, distinctly punctate; specula granulate, matte; dorsal impressions finely striate. Prepectal carina not or slightly elevated ventrally, absent on the transversal parts. Metapleura finely granulate and punctate; coxal carinae absent. Propodeum rugose, with basal carinae including area basalis and basal half of area superomedia; area superomedia c.1.5x longer than wide; area petiolaris slightly and widely impressed. Hind femora length 4.7x width; length of inner spurs of hind tibiae 0.6x hind metatarsus length. Areolets stalked, 2 nd recurrent veins distal of middle; nervuli slightly postfurcal; postnervuli intercepted behind middle; external angles of discoidal cells c.90°; nervelli of hind wing intercepted in apical 0.6, sometimes not intercepted. 2 nd tergite length 1.0-1.2x width, 3 rd tergite length 0.6-0.7x width; distance of thyridia from tergite bases 0.5-1.0x its length.

Area superomedia about as long as wide. Hind femora length 4.7x width. 2 nd recurrent veins reaching areolets in the middle. Nervuli interstitial (rarely antefurcal); nervelli of hind wing interstitial, intercepted in apical 0.7. 2 nd tergite length 1.1x width; 3 rd tergite length 0.65x width. 3 rd tergite red, with blackish base; hind tibiae blackish, with pale yellow stripe externo-medially.
