Celesterion gen. nov.

Type species: Celesterion reticulatum sp. nov.

Etymology. No specific meaning intended. The gender is neuter.

Diagnosis. Head large with large eyes in female ( Figs 14 View FIGURES 11–14 , 17 View FIGURES 15–18 ). Antenna in both sexes with six flagellomeres: four funiculars and two claval segments ( Figs 17, 18 View FIGURES 15–18 ), male flagellomeres unbranched ( Fig. 18 View FIGURES 15–18 ). Thoracic dorsum with very strong reticulation ( Figs 11 View FIGURES 11–14 , 15 View FIGURES 15–18 ); mesoscutum with notauli absent, midlobe with four pairs of setae; mesoscutellum without longitudinal grooves, with two pairs of setae. Propodeum with two submedian, somewhat irregular carinae ( Fig. 16 View FIGURES 15–18 ). Fore wing with postmarginal vein 0.8× as long as stigmal vein ( Fig. 13 View FIGURES 11–14 ). Petiole very short. Female and male are very similar.

Description. Head with large eyes in female, smaller in male; with a complete and slightly curved malar sulcus; clypeus semicircular with ventral margin straight; antennal scrobes undelimited and smooth; occipital margin carinate; occiput concave in dorsal view, with strong reticulation. Antennae inserted distinctly above lower level of eyes but with scape short, not reaching anterior ocellus; scape wider in male; with six flagellomeres: four funiculars and two claval segments, no anelli visible; male with unbranched flagellomeres. Pronotum reduced, barely visible in dorsal view, without a carina along anterior margin of pronotal collar. Mesoscutum with very strong reticulation throughout; midlobe with four pairs of setae; notauli absent. Mesoscutellum with very strong reticulation throughout, without grooves, with two pairs of setae, one pair attached close to anterior margin, and one pair attached posterolaterally. Axillae with strong reticulation, advanced forward by half their length in front of transscutal articulation. Dorsellum with strong reticulation and with posterior margin rounded. Propodeum with two submedian, somewhat irregular carinae, with reticulation on either side of carinae; spiracles with a short longitudinal carina from anterior margin, carina directed towards lateral panels of metanotum; callus with strong reticulation and with 7–9 setae. Fore wing with four setae close to antero-apical margin, and with a complete row, consisting of nine setae, on ventral surface; with a row of admarginal setae along entire marginal vein on ventral side of membrane; postmarginal vein 0.8× as long as stigmal vein. Hind leg with tibial spur ½ the length of basitarsus. Petiole very short, barely visible in dorsal view. Gaster with Gt 1-2 smooth, Gt 3-7 with weak reticulation.
