M a t e r i a l e x a m i n e d: Holotypus: (♀) Gabon - prov. Ogooué-Ivindo, Parc National de ĺ Ivindo , station de Ipassa , 0°30́45́́N 12°48́10́́ E, 20/29.II. 2012, leg. M. Pavesi ( MSNM, Milan ).

R e m a r k: This new species resembles C. corrugata TOSQUINET, but differs by the reduced yellowish coloration of the head, wider malar space and the distinct apical lamella of hind coxa.

D e s c r i p t i o n: ♀: Body length 14 mm. Flagellum long, very slightly lanceolate, with 40 flagellomeres, 1 st and 2 nd flagellomeres each c.3.5x longer than wide; widest flagellomeres about as long as wide. Temple long, parallel behind eye and slightly narrowed apically, c.0.65x as wide as the eye. Distance of lateral ocellus to eye 1.4x its diameter. Temple and frons smooth and shining. Face and clypeus densely and finely punctate; gena with scattered punctures ventrally. Mandible large and wide, with a wide gap between both teeth, lower tooth slightly shorter than the upper one. Malar space c.1.3x longer than the width of mandibular base. Genal carina reaching mandibular base.

Pronotum with oblique striae caudally and ventrally, epomia strongly developed, very long. Mesoscutum without distinct notaulus, with coarse irregular rugae and three smooth stripes medially and in the centers of lateral fields. Mesopleuron strongly striate dorsally and punctate-striate ventrally, speculum smooth. Metapleuron rugose-punctate, juxtacoxal carina distinct. Scutellum flat, about as long as wide, coarsely rugose, with complete lateral carina. Propodeum rugose-punctate; area superomedia c.1.4x longer than wide, with rounded sides and obsolete apical carina, smooth; area superoexterna finely striate. Hind coxa coarsely punctate, with moderately raised apical lamella; hind femur with dense punctures, c.3.9x longer than wide. Claws not pectinate.

Areolet quadrangular and shortly stalked; 2 nd recurrent vein proximal to its middle; nervulus slightly postfurcal (by 1x its width). Nervellus of hind wing reclivous, intercepted in its apical 0.75.

Metasoma semi-amblypygous, short-oval. Postpetiolus moderately widened apically, without dorsal carina, finely aciculate and punctate. Gastrocoelus triangular, with fine ridges. Thyridium wide, oblique, c.1.5x as wide as the interval. 2 nd tergite 1.05x wider than long, 3 rd tergite 1.4x wider than long, both tergites completey and coarsely aciculate; following tergites smooth and with fine scattered punctures, strongly shining. Ovipositor sheath not surpassing the metasomal apex.

Color: Head black. Reddish are base of mandible and spot on malar space. Small spots opposite to antennal grooves yellowish. Flagellum black, with ivory stripes on flagello- meres 7-14. Mesosoma black with metallic blue shine. Metasoma blackish with metallic coppery shine; 7 th tergite with wide ivory apical band. Fore and middle legs except blackish coxae reddish, fore and middle femora and tibiae with brownish stripes dorsally; fore and middle tarsi brown; hind leg black, hind femur red in basal half. Wings hyaline, apices diffusely infuscate distally to pterostigma; pterostigma blackish.

Male and hosts unknown.
