( Figs 33–37 View FIGURES 33 – 37 , 55 View FIGURES 52 – 57 , 83, 84 View FIGURES 74 – 88 )
Diagnosis. Vertex with a complete median groove and with a groove delimiting posterior part of ocellar triangle ( Fig. 35 View FIGURES 33 – 37 ); scutellum with a deep and distinct median groove in anterior 2/3 ( Fig. 36 View FIGURES 33 – 37 ); propodeum with a complete median carina ( Fig. 37 View FIGURES 33 – 37 ); hind coxa conspicuously hairy on posterior surface; petiole 2X as long as wide and reticulate with small meshes; first gastral tergite shiny and large, covering 2/3 the length of gaster.
Similar to C. petiolatum and C. unicornis , but differing from the former in having a shorter petiole and from the latter in lacking a horn on the upper-median frons.
Description. FEMALE. Length 1.2–1.4 mm. Antenna dark brown except scape usually white (specimen from Altamira with basal 2/3 dark brown). Frons metallic dark purple. Vertex metallic bluish-purple or bluish-green. Mesoscutum metallic bluish-purple or bluish-green. Scutellum with anterior 2/3 metallic bluish-purple or bluishgreen, posterior 1/3 metallic dark purple. Propodeum metallic bluish-green. Coxae dark and metallic; femora, tibiae and tarsi white (specimen from Altamira with femora predominantly dark brown). Wings hyaline. Petiole metallic dark purple. Gaster with first tergite metallic bluish-purple, remaining tergites metallic purple.
Antenna as in Fig. 83 View FIGURES 74 – 88 . Frons smooth and shiny ( Figs 33, 34 View FIGURES 33 – 37 ); antennal scrobes uniting below frontal suture; frontal suture incomplete, terminating at the distance equal to one ocellus from each eye; tentorial pits missing ( Fig. 33 View FIGURES 33 – 37 ). Vertex smooth and shiny ( Fig. 35 View FIGURES 33 – 37 ), medially with a groove between occipital margin and anterior ocellus.
Mesonotum with a more or less round fovea medially between mesoscutum and scutellum ( Fig. 36 View FIGURES 33 – 37 ). Mesoscutum smooth and shiny ( Fig. 36 View FIGURES 33 – 37 ) except midlobe with strong pitlike reticulation along anterior margin. Scutellum with anterior 2/3 smooth and shiny except for distinct median groove ( Fig. 36 View FIGURES 33 – 37 ), posterior 1/3 with raised, strong reticulation. Dorsellum hidden under scutellum, not visible in dorsal view ( Fig. 36 View FIGURES 33 – 37 ). Propodeum with a complete, strong median carina, smooth and shiny between plicae ( Fig. 37 View FIGURES 33 – 37 ).
Petiole 2X as long as wide and reticulate with small meshes, hence dull ( Fig. 37 View FIGURES 33 – 37 ). Gaster ovate with first gastral tergite shiny and large, covering 2/3 length.
MALE. Length 1.1 mm. Colour as in female. Antenna as in Fig. 84 View FIGURES 74 – 88 . Structure otherwise as in female.
