Remark: This new species is closely related to C. morionella HOLMGREN, but was already separated by R. HINZ (unpublished). It differs slightly by the features mentioned in the key.
D e s c r i p t i o n: ♀: Body length 6-6.5 mm. Flagella stout, with 27 segments; 1 st flagellomeres length 3.3x width; preapical flagellomeres slightly longer than wide or square. Temples narrow, strongly but roundly narrowed behind eyes; head 2.3x wider than long. Distance of lateral ocelli to eyes 0.8x and between them 1.5x their diameter. Face slightly narrowed ventrally, finely granulate, minimal width 0.6x eye length and 0.9x width of frons. Malar space length 0.3x 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 finely granulate, without distinct punctures; specula granulate, matte; dorsal impressions slightly developed, only with fine rows of granulae. Prepectal carina narrow, absent on transversal parts. Metapleura finely granulate; coxal carinae absent. Propodeum with complete strong carinae; area superomedia as long as wide; area petiolaris slightly but widely impressed, with irregular transversal rugae. Hind femora length 4.3x width; length of inner spurs of hind tibiae 0.65x hind metatarsi length. Areolets usually sessile or shortly stalked, 2 nd recurrent veins in the middle; nervuli postfurcal; postnervuli intercepted below the middle; external angles of discoidal cells acute (70-75°); nervelli of hind wing distinctly intercepted in apical 0.8. 2 nd tergite length 1.05-1.1x width; distance of thyridia from basal margin 0.5-1x their length; 3 rd tergite length 0.7x width.
Colour: Black. Palps, mandibles except teeth, and tegulae yellow. Scapes and pedicels partly reddish. Metasoma black. Legs reddish; fore and middle coxae and trochanters often reddish, rarely yellowish; hind coxae and trochanters black, rarely partly reddish; hind femora slightly darkened apically; hind tibiae reddish, yellowish externally, almost not darkened subbasally and apically; hind tarsi except yellow basal spots on hind metatarsi reddish. Pterostigmata yellowish-brown.
♂: Body length 6.5 mm. Flagella with 28-29 segments. Mesopleura granulate, with very fine superficial punctures; dorsal impressions with fine striation. Area superomedia slightly wider than long. Hind femora length 4.2x width. 2 nd tergite length 1.2x width; 3 rd tergite length 0.85x width. Scapes and pedicels yellow internally. Hind coxae and trochanters brownish.
