D e s c r i p t i o n: ♀: Body length 6-7 mm. Flagella with 31-34 segments; 1 st flagellomeres length c.3.5x width; preapical flagellomeres about square. Temples narrow, moderately narrowed behind eyes; head 2.3x wider than long. Distance of lateral ocelli to eyes 0.7-0.8x and between them 1.6x their diameter. Face strongly narrowed ventrally, finely rugose-punctate, minimal width 0.6x eye length and 0.9x width of frons. Malar spaces length 0.4x width of mandibular bases. Genal carinae slightly bent outwards, weak ventrally, reaching mandibular bases in an acute angle. Hypostomal carinae not elevated.

Mesopleural discs granulate, with superficial punctures; specula granulate, matte; dorsal impressions with fine striae. Prepectal carina narrow, absent on transversal parts. Metapleura finely rugose; coxal carinae not developed. Propodeum with short basal carinae (usually area basalis+area superomedia), sometimes indistinct; area superomedia about as long as wide; area petiolaris slightly impressed medially, rugose. Hind femora length 4.5-5.1x width; length of inner spurs of hind tibiae 0.67x hind metatarsus length. Hind claws pectinate. Areolets stalked, 2 nd recurrent veins slightly proximal or distal to middle; nervuli strongly postfurcal; postnervuli intercepted in or below its middle; external angles of discoidal cells acute (70-80°); nervelli of hind wing interstitial or slightly anteclivous, intercepted in the apical 0.7. 2 nd tergite length 1.7-2.0x width; thyridia roundish, distance to basal margins almost 1.9-2x their length; 3 rd tergite length 0.95-1.05x width.

Colour: Black. Palps, mandibles, usually scapes and pedicels ventrally, tegulae, fore and middle coxae, all trochanters and trochantelli yellow.
