(Figs 18–22, 78, 79)
Diagnosis. Upper part of frons with two "horns" and with frontal suture continuing up into apex of horns (Figs 18, 19); scape, femora and tibiae white; scutellum with a deep and distinct median groove extending from anterior margin along ½ length (Fig. 21); hind coxa conspicuously hairy on posterior surface; propodeum without median carina (Fig. 22); petiole 1.5X as long as wide, widest and with irregular transverse carinae in anterior half, and with a constriction posteriorly (Fig. 22); first gastral tergite covering about 1/3 of gaster.
Similar to C. diceros, but differing in the shape of petiole, and vertex with an ovate pit inside ocellar triangle; also similar to C. bicornis, but differing in having scape, femora and tibiae white and a large fovea medially between mesoscutum and scutellum (Fig. 21).
Description. FEMALE. Length 1.3 mm. Antenna dark brown except scape white. Frons golden-green. Vertex, mesoscutum, scutellum and propodeum metallic bluish-green. Coxae dark and metallic; femora, tibiae and tarsi white. Wings hyaline. Petiole metallic bluish-green. Gaster dark brown with metallic bluish-purple tinges.
Antenna as in Fig. 78. Frons smooth and shiny (Figs 18, 19); upper part of frons with two "horns"; tentorial pits distinct (Fig. 19); frontal suture incomplete, ending just below frontal horns and not reaching eyes. Vertex smooth and shiny (Fig. 20), medially with a groove between occipital margin and anterior ocellus, the groove extending into an ovate pit inside ocellar triangle.
Mesonotum with a more or less round fovea medially between mesoscutum and scutellum (Fig. 21). Mesoscutum predominantly smooth and shiny (Fig. 21), anterior margin with rows of strong foveae and sidelobes with engraved and very weak reticulation. Scutellum smooth and shiny over anteromedian ½ except for a distinct median groove, and with engraved reticulation of elongate meshes over anterolateral ½ (Fig. 21) and raised, strong, isodiametric meshlike reticulation over posterior ½. Dorsellum hidden under scutellum, not visible in dorsal view (Fig. 21). Propodeum smooth and shiny between plicae (Fig. 22).
Petiole 1.5X as long as wide, with irregular transverse carinae (Fig. 22). Gaster ovate with first tergite covering about ½.
MALE. Length 1.2–1.3 mm. Scape yellowish-brown or white. Frons metallic dark purple, golden-green along eyes. Vertex golden-red or metallic red. Midlobe of mesoscutum golden-red or metallic red, sidelobes metallic dark purple. Scutellum with anterior ½ metallic dark purple with golden-red tinges or metallic red, posterior ½ metallic dark purple with bluish-green tinges. Propodeum golden-green or golden-red. Legs with femora and hind tibia pale brown, fore and mid tibiae yellowish-brown, tarsi white. Petiole black with metallic bluish-green tinges. Gaster dark brown with metallic purple tinges and with a large white spot in anteromedian 1/3. Antenna as in Fig. 79. Structure otherwise as in female.
