Cornugon albicoxa sp. nov.

( Figs 2–7 , 74 )

Diagnosis. Vertex without median groove ( Fig. 4 ); pronotal collar carina very weak ( Fig. 3 ); scutellum with a deep and distinct median groove extending along entire length ( Fig. 3 ); propodeum without median carina ( Fig. 5 ); coxae white; petiole about as long as wide; first gastral tergite covering about 1/3 of gaster.

Similar to C. anais , but differing in having a complete median groove on scutellum, and longer propodeum with plicae.

Description. FEMALE. Length 1.0 mm. Antenna dark brown except scape white. Frons metallic purple. Vertex metallic greenish-blue. Mesoscutum, scutellum and propodeum golden-green. Legs white. Wings hyaline. Petiole golden-green. Gaster weak golden-green.

Antenna as in Fig. 74 . Frons and vertex smooth and shiny ( Figs 2, 4 ), upper part of frons concave, otherwise almost flat; vertex without median groove. Tentorial pits indistinct ( Fig. 2 ).

Mesonotum with a more or less triangular fovea medially between mesoscutum and scutellum ( Fig. 3 ). Pronotal collar with transverse carina very weak ( Fig. 3 ). Midlobe of mesoscutum anteriorly with weak transverse striae ( Fig. 3 ), posterior part of midlobe with very weak engraved reticulation, sidelobes with very weak engraved reticulation posteriorly, otherwise smooth and shiny. Scutellum smooth and shiny medially ( Fig. 3 ), laterally and posteriorly with weak reticulation; with a deep and distinct median groove extending along entire length. Dorsellum very short, almost hidden under scutellum with only very posterior parts visible in dorsal view ( Fig. 5 ). Propodeum with very weak sculpture and shiny between plicae ( Fig. 5 ).

Petiole about as long as wide. Gaster ovate with first tergite covering about 1/3 length.

MALE. Unknown.

Type material. Holotype female ( TAMU) labelled “ Mexico, Oaxaca, 9 miles west of Tehuantepec, 13.vii.1987, 87/039, G. Zolnerowich”.
