( Figs 42–47 View FIGURES 42 – 47 , 56 View FIGURES 52 – 57 , 86, 87 View FIGURES 74 – 88 )

Diagnosis. Vertex anteriorly and upper part of frons with raised, very strong reticulation ( Figs 42–44 View FIGURES 42 – 47 ); vertex with a weak median groove ( Fig. 44 View FIGURES 42 – 47 ); male flagellomeres strongly pedunculate ( Fig. 86 View FIGURES 74 – 88 ); scutellum without median groove ( Fig. 45 View FIGURES 42 – 47 ); propodeum without median carina ( Fig. 47 View FIGURES 42 – 47 ); petiole 1.5X as long as wide, widest anteriorly and narrowing posteriorly (as in Fig. 22 View FIGURES 18 – 22 ), with transverse carinae and shiny; first gastral tergite covering about 1/3 of gaster.

Similar to C. gibberum , but differing in having upper part of frons and vertex strongly reticulate.

Description. FEMALE. Length 1.1–1.5 mm. Antenna black with metallic green tinges except scape white. Frons black with metallic green tinges. Vertex metallic bluish-green. Mesoscutum metallic bluish-green. Scutellum with anterior ½ (striate part) metallic bluish-green, posterior ½ (reticulate part) golden-green. Propodeum metallic bluish-green. Coxae dark and metallic; femora, tibiae and tarsi white. Wings hyaline. Petiole golden-green. Gaster metallic bluish-purple or metallic bluish-green.

Antenna as in Fig. 87 View FIGURES 74 – 88 . Frons smooth and shiny except with raised, very strong reticulation above frontal speculum ( Fig. 42 View FIGURES 42 – 47 ); antennal scrobes uniting below frontal suture; frontal suture incomplete, terminating at a distance equal to 1/3 diameter of anterior ocellus from each eye margin; tentorial pits distinct ( Fig. 42 View FIGURES 42 – 47 ). Vertex with raised, very strong reticulation inside, lateral to, and in front of ocellar triangle ( Fig. 44 View FIGURES 42 – 47 ), but smooth and shiny behind ocellar triangle; medially with a groove extending from occipital margin to ocellar triangle.

Mesonotum with a triangular fovea medially between mesoscutum and scutellum ( Fig. 45 View FIGURES 42 – 47 ). Mesoscutum with raised, weak reticulation, the meshes transverse ( Fig. 45 View FIGURES 42 – 47 ). Scutellum with strong longitudinal striae to smooth medially in anterior ½, and with raised, strong reticulation in posterior ½ ( Fig. 45 View FIGURES 42 – 47 ). Dorsellum mostly hidden under scutellum in dorsal view, with just lateral parts extending out from under scutellum ( Fig. 45 View FIGURES 42 – 47 ). Propodeum smooth and shiny between plicae ( Fig. 47 View FIGURES 42 – 47 ).

Petiole 1.4X as long as wide, with transverse carinae and shiny ( Fig. 47 View FIGURES 42 – 47 ). Gaster ovate with first gastral tergite covering about 1/3 length.

MALE. Length 1.3–1.5 mm. Scape pale brown to white. Smooth part of vertex golden or golden-green. Mesoscutum golden or metallic dark purple. Scutellum with anterior ½ golden, golden-green or metallic dark purple. Femora and hind tibia dark brown or white. Gaster dark brown with metallic tinges, with a large white spot in anteromedian ½. Antenna as in Fig. 86 View FIGURES 74 – 88 . Structure otherwise similar to female except eyes smaller and malar space larger, and antennal scrobes uniting on frontal suture ( Fig. 43 View FIGURES 42 – 47 ).
