Holotypus: (♀) 24.7.1959 Kaltern, legit. R. Hinz; [red] 1408 (ZSM).

R e m a r k: This new species is closely related to C. dubia TSCHEK. It can be differentiated by higher number of flagellomeres, smaller ocelli, stouter metasoma, and completely dark trochanters and trochantelli.

Description: ♀: Body length 7.5 mm. Flagella with 35 segments; 1 st flagellomeres length c.3x width; preapical flagellomeres longer than wide. Head transverse, width 2.4x length. Temples narrow, strongly and roundly narrowed behind eyes. Ocelli small, distance of lateral ocelli to eyes 1.0x and between them 1.6x their diameter. Face strongly narrowed ventrally, rugose-punctate, minimal width 0.6x eye length and 0.85x width of frons. Malar space length 0.4x width of mandibular bases. Genal carinae strongly bent outwards ventrally, reaching mandibular bases in an angle of almost 90°. Hypostomal carinae not or slightly elevated.

Mesopleural discs granulate and superficially punctate; specula granulate, matte; dorsal impressions with moderately strong striae. Prepectal carina narrow, absent on transversal parts. Metapleura finely rugose; coxal carinae absent. Propodeum without distinct carinae, finely rugose; area petiolaris with moderately deep central impression, in apical third with fine transverse striation. Hind femora length 5.0x width, length of inner spurs of hind tibiae 0.8x hind metatarsi length. Areolets stalked, 2 nd recurrent veins distal to their middle; nervuli postfurcal; postnervuli intercepted in their middle; external angles of discoidal cell acute (75-80°); nervelli of hind wings strongly reclivous, not distinctly intercepted. 2 nd tergite length 1.6x width; distance of thyridia from basal margins 1.5x their length; 3 rd tergite length 0.95x width.

Colour: Black. Palps yellow; mandibles and tegulae blackish. Metasoma black. Coxae, trochanters and trochantelli black; fore and middle legs reddish; fore and middle tibiae and tarsi yellowish externally; middle femora chestnut-brown; hind femora dark brownish, with very narrow yellowish-red spot basally; hind tibiae brown, cream-yellow basally and externo-medially; hind tarsi except wide yellowish bases of metatarsi brown. Pterostigmata brown.
