Cornugon diabolos sp. nov.
( Figs 18–22 View FIGURES 18 – 22 , 78, 79 View FIGURES 74 – 88 )
Diagnosis. Upper part of frons with two "horns" and with frontal suture continuing up into apex of horns ( Figs 18, 19 View FIGURES 18 – 22 ); scape, femora and tibiae white; scutellum with a deep and distinct median groove extending from anterior margin along ½ length ( Fig. 21 View FIGURES 18 – 22 ); hind coxa conspicuously hairy on posterior surface; propodeum without median carina ( Fig. 22 View FIGURES 18 – 22 ); petiole 1.5X as long as wide, widest and with irregular transverse carinae in anterior half, and with a constriction posteriorly ( Fig. 22 View FIGURES 18 – 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 View FIGURES 18 – 22 ).
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 View FIGURES 74 – 88 . Frons smooth and shiny ( Figs 18, 19 View FIGURES 18 – 22 ); upper part of frons with two "horns"; tentorial pits distinct ( Fig. 19 View FIGURES 18 – 22 ); frontal suture incomplete, ending just below frontal horns and not reaching eyes. Vertex smooth and shiny ( Fig. 20 View FIGURES 18 – 22 ), 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 View FIGURES 18 – 22 ). Mesoscutum predominantly smooth and shiny ( Fig. 21 View FIGURES 18 – 22 ), 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 View FIGURES 18 – 22 ) and raised, strong, isodiametric meshlike reticulation over posterior ½. Dorsellum hidden under scutellum, not visible in dorsal view ( Fig. 21 View FIGURES 18 – 22 ). Propodeum smooth and shiny between plicae ( Fig. 22 View FIGURES 18 – 22 ).
Petiole 1.5X as long as wide, with irregular transverse carinae ( Fig. 22 View FIGURES 18 – 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 View FIGURES 74 – 88 . Structure otherwise as in female.
