Diagnosis. Upper part of frons with two "horns" and with frontal suture continuing up into apex of horns (Figs 13– 15); scape, femora and tibiae dark brown with metallic tinges; mesoscutum smooth and shiny (Fig. 16); scutellum with a deep and distinct median groove extending from anterior margin along 3/4 length (Fig. 16); propodeum without median carina (Fig. 17); hind coxa conspicuously hairy on posterior surface; petiole about 1.5X as long as wide, reticulate with small meshes and hence dull (Fig. 17); first gastral tergite shiny and large, covering 4/5 of gaster.
Similar to C. diabolos, but differing in having scape, femora and tibiae dark brown and with a narrow fovea medially between the mesoscutum and scutellum (Fig. 16).
Description. FEMALE. Length 1.0 mm. Antenna dark. Frons dark purple. Vertex golden-green. Mesoscutum golden-green with blue tinges anteriorly. Scutellum golden-purple, metallic greenish-blue laterally. Propodeum golden-green. Coxae, femora and tibiae dark and metallic with knees pale; tarsi pale brown. Wings hyaline. Gaster and petiole dark metallic purple.
Antenna as in Fig. 76. Frons and vertex smooth and shiny (Figs 13–15), frons concave; upper part of frons with two "horns"; tentorial pits distinct (Fig. 13); frontal suture incomplete, ending just below frontal horns; frontal speculum small.
Mesonotum with a narrow slit medially between mesoscutum and scutellum (Fig. 16). Mesoscutum smooth and shiny (Fig. 16). Scutellum with anterior 4/5 smooth and shiny, posterior 1/5 with strong reticulation (Fig. 16); with a distinct median groove extending from anterior margin along 3/4 length. Dorsellum hidden under scutellum, not visible in dorsal view (Fig. 16). Propodeum with irregular sculpture medially, otherwise smooth and shiny between plicae (Fig. 17).
