R e m a r k: The new taxon resembles C. kriechbaumeri (COSTA), but can be easily differentiated by the ventrally elevated prepectal carina in both sexes and the less rugose mesopleura in ♀. In ♂, scapes are usually yellowish ventrally.
D e s c r i p t i o n: ♀: Body length 7-8 mm. Flagella with 31 segments; 1 st flagellomeres length 2.7x width; preapical flagellomeres slightly longer than wide or square. Temples narrow, roundly narrowed behind eyes; head 2.2x wider than long. Ocelli large, distance of lateral ocelli to eyes 0.6x and between them 1.5x their diameter. Face strongly narrowed ventrally, finely rugose-punctate, minimal width 0.8x frontal width and 0.55x eye length. Malar space length 0.4x width of mandibular bases. Genal carinae strongly bent outwards ventrally, reaching mandibular bases in an angle of 90°; genae concave ventrally. Hypostomal carinae not elevated.
Sides of pronotum with strong striation, dorsally punctate. Mesopleural discs punctate and grnaultae or finely rugulose; specula granulate but shining; dorsal impressions strongly striate. Prepectal carina lamelliform elevated ventrally, narrow on mesopleural part, not developed on transversal parts. Propodeum rugose, without distinct carinae, with strong and narrow central longitudinal impression covered with some transversal rugae. Hind femora length 5.0x width; inner spurs of hind tibiae 0.8x as long as hind metatarsi. Hind claws pectinate. Areolets stalked, 2 nd recurrent veins in the middle; nervuli postfurcal; postnervuli intercepted in the middle; external angles of discoidal cells acute (70-80°); nervelli of hind wings reclivous, not distinctly intercepted. 2 nd tergite length c.2.2x width; thyridia roundish, distance to basal margins of tergite 2x their length; 3 rd tergite length 1.1x width.
Colour: Black including flagella and mandibles. Palps and tegulae yellow. Scapes sometimes reddish or yellow ventrally. Metasoma blackish. Coxae, trochanters and trochantelli black; trochanters and trochantelli with narrow yellow stripes apically; legs otherwise reddish; fore and middle tibiae ivory externally; fore and middle tarsi ± brownish; hind femora narrowly infuscate at apex; hind tibiae reddish-brown to blackish, ivory basally and externo-medially; hind tarsi except narrow ivory bases of metatarsi blackish. Pterostigmata brown.
♂: Body length 8 mm. Flagella with 30-32 segments; preapical flagellomeres longer than wide. Discs of mesopleura rugose-punctate, rugosity usually stronger than in females. Hind femora length 5.1-5.3x width. 2 nd tergite length 2.1-2.3x width; 3 rd tergite about as long as wide. Scapes usually with ventral reddish-yellow marks. Mandibles except teeth yellowish or blackish. Fore and middle tarsi reddish, ± brownish apcially. Hind femora red, sometimes basally and apically infuscate. Wings sometimes slightly brownish. Structure and coloration otherwise as in ♀.
