description
D e s c r i p t i o n: ♀: Body length 6.5 - 7.5 mm. Flagella with 29 - 32 segments; 1 st flagellomeres length 3.6 - 4.0 x width; preapical flagellomeres slightly longer than wide. Temples narrow, roundly narrowed behind eyes, width 0.5 x eye width; head 2.2 x wider than long. Ocelli small, distance of lateral ocelli to eyes 1.0 x and between them 1.6 - 1.9 x their diameter. Face strongly narrowed ventrally, finely rugose-punctate, minimal width 0.57 x eye length and 0.85 x width of frons. Malar space length 0.3 x width of mandibular bases. Genal carinae ± bent outwards ventrally, reaching at mandibular bases in an angle of 80 - 90 °. Hypostomal carinae not elevated. Mesopleural discs granulate and ± punctate (sometimes superficially); specula granulate, matte; dorsal impressions finely striate; metapleura rugulose-punctate, in the ventral parts with some rugae; coxal carinae absent. Prepectal carina narrow, absent on transversal parts. Propodeum with basal carinae (area basalis and 1 / 3 of area superomedia); area petiolaris not distinctly impressed, rugulose and with some transverse rugae apically. Hind femora length 4.5 - 4.8 x width. Hind claws pectinate. Areolets stalked, 2 nd recurrent veins distal of middle; nervuli postfurcal; postnervuli intercepted behind its middle; external angles of discoidal cells acute (80 °); nervelli of hind wing reclivous, not intercepted. 2 nd tergite length 1.8 - 2.2 x width; distance of thyridia from basal margin 0.5 - 1 x their length; 3 rd tergite length 0.9 - 1.15 x width. Colour: Black. Palps reddish-yellow; mandibles except reddish teeth black, rarely yellow; tegulae yellow. All coxae and trochanters black; legs otherwise red; hind tibiae ivory basally, red or reddish-yellow externo-medially, pale brownish subbasally and apically; hind tarsi except ivory base of hind metatarsi dark brown. Pterostigmata brown. ♂: Body length 7 - 8 mm. Flagella with 29 - 35 segments; 1 st flagellomere length 2.5 x width; preapical flagellomeres about square. Distance of lateral ocelli to eyes 0.7 x their diameter. Face slightly narrowed ventrally, finely rugose-punctate, minimal width 0.63 x eye length and 0.95 x width of frons. Malar space length 0.3 x width of mandibular bases. Mesopleural discs granulate and distinctly punctate; specula granulate, matte; dorsal impressions strongly striate. Prepectal carina not elevated and absent on transversal parts. Propodeum with basal carinae (area basalis and 1 / 3 of area superomedia); area petiolaris usually with rather deep and narrow central impression, the impression with transverse rugae. Hind femora length 4.5 x width. Areolets stalked, 2 nd recurrent veins in their middle; nervuli distinctly postfurcal; postnervuli intercepted behind its middle; external angles of discoidal cells acute (80 °). 2 nd tergite length 2.4 x width; distance of thyridia from basal margin 2 x their length; 3 rd tergite length 1.05 x width. Colour: Black. Palps reddish-yellow; mandibles except reddish teeth black; tegulae yellow; scapes and pedicels sometimes reddish ventrally. All coxae and trochanters black; legs otherwise red; hind tibiae ivory basally and externo-medially, brownish subbasally and apically. Pterostigmata brown.
