(
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.

Cornugon diabolos
sp. nov.
18. Head frontal, female. 19. Head frontal, male. 20. Vertex, female. 21. Mesosoma dorsal, female. 22. Propodeum dorsal, female.
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.
