( Figs 38–41 View FIGURES 38 – 41 , 88 View FIGURES 74 – 88 )
Diagnosis. Vertex with two humps, one behind each posterior ocellus, with a complete median groove and with a groove delimiting posterior part of ocellar triangle ( Fig. 41 View FIGURES 38 – 41 ); scutellum with a deep and distinct median groove extending from anterior margin along ¾ of length ( Fig. 39 View FIGURES 38 – 41 ); hind coxa conspicuously hairy on posterior surface; propodeum with a complete and strong median carina ( Fig. 40 View FIGURES 38 – 41 ); petiole about 3.5X as long as wide and reticulate with small meshes ( Fig. 40 View FIGURES 38 – 41 ); first gastral tergite shiny and large, covering 2/3 length of gaster.
Similar to C. leios and C. unicornis , but differing from both in having a very long petiole, and from the latter also in not having a horn on the upper-median frons.
Description. FEMALE. Length 1.4 mm. Antenna dark brown except scape white. Frons metallic dark purple, golden-green along eyes. Vertex metallic greenish-blue. Mesoscutum golden-green anteriorly, metallic greenishblue posteriorly. Scutellum metallic greenish-blue with metallic purple tinges posteriorly. Propodeum goldengreen. Coxae dark and metallic; femora, tibiae and tarsi white. Wings hyaline. Petiole metallic purple. Gaster weak metallic greenish-blue.
Antenna as in Fig. 88 View FIGURES 74 – 88 . Frons and vertex smooth and shiny ( Figs 38, 41 View FIGURES 38 – 41 ), frons concave; frontal suture reaching eyes at level of anterior ocellus; tentorial pits missing; vertex with two humps, one behind each ocellus.
Mesonotum with a more or less round fovea medially between mesoscutum and scutellum ( Fig. 39 View FIGURES 38 – 41 ). Midlobe of mesoscutum with weak reticulation, the meshes transverse, and sidelobes with engraved transverse reticulation ( Fig. 39 View FIGURES 38 – 41 ). Scutellum with anterior 1/2 smooth and shiny and posterior 1/2 with raised, strong reticulation ( Fig. 39 View FIGURES 38 – 41 ), but with a deep, distinct median groove extending from anterior margin along 3/4 length. Dorsellum short, with posterior parts visible in dorsal view ( Fig. 39 View FIGURES 38 – 41 ). Propodeum with a complete and strong median carina ( Fig. 40 View FIGURES 38 – 41 ), smooth and shiny between plicae.
Petiole about 3.5X as long as wide and reticulate with small meshes, hence dull ( Fig. 40 View FIGURES 38 – 41 ). Gaster ovate with first tergite shiny and large, covering 2/3 length.
MALE. Unknown.
