R e m a r k: This species resembles C. stygia TSCHEK but differs by the following features: metasoma stouter, preapical flagellomeres square or slightly longer than wide, sculpture of mesopleura slightly stronger, colour of hind tibiae paler, area superomedia wider, malar spaces longer.

D e s c r i p t i o n: ♀: Body length 5-6 mm. Flagella with 29 segments; 1 st flagellomeres length 3.6x width; preapical flagellomeres slightly longer than wide or square. Temples narrow and strongl narrowed behind eyes; head 2.3-2.4x wider than long. Distance of lateral ocelli to eyes 0.6x and between them 1.3x their diameter. Face moderately narrowed ventrally, finely rugose-punctate, minimal width 0.72x eye length and 0.9x frons width. Malar space length 0.5x width of mandibular bases. Genal carinae not bent outwards and obsolete ventrally, reaching hypostomal carinae far from mandibular bases in an acute angle of 70°. Hypostomal carinae not elevated.

Mesopleural discs granulate and finely rugulose, superficially punctate; specula granulate, matte; dorsal impressions with fine striae. Prepectal carina narrow and absent on the transversal parts. Metapleura finely rugose; coxal carinae partly developed. Propodeum with complete carinae; area superomedia wider than long (2x), costulae usually absent; area petiolaris moderately impressed, with irregular rugae. Hind femora length 4.2-4.3x width; length of inner spurs of hind tibiae 0.67x hind metatarsus length. Areolets stalked, 2 nd recurrent veins distal of middle; nervuli strongly postfurcal; postnervuli intercepted behind the middle; external angles of discoidal cells acute (70°); nervelli of hind wing intercepted in the apical 0.6-0.7. 2 nd tergite length 1.0-1.1x width; thyridia usually transverse, distance to basal margins 0.5-1x their length; 3 rd tergite length 0.65-0.75x width.

Colour: Black. Palps and mandibles yellow. Tegulae reddish-yellow. Scapes and pedicels often reddish or yellowish internally. All coxae black, fore and middle coxae sometimes reddish apically; trochanters and trochantelli reddish-yellow, hind trochantelli dark; fore and middle legs reddish; fore and middle tibiae yellowish externally; hind femora reddish-brown or blackish; hind tibiae reddish, yellowish to ivory basally and externomedially, brown subbasally and apically; hind tarsi except pale basal half of metatarsi brown. Pterostigmata brown.

♂: Flagella with 27-28 segments. Distance of lateral ocelli to eyes 0.6-0.9x and between them 1.4x their diameter. Hind femora length 4.1x width. 2 nd tergite length 1.15x width; 3 rd tergite length 0.70x width. Hind trochantelli yellow-red. Structure and colour otherwise as described for the ♀.
