Eucharis festiva Fabricius, 1804: 157 View in CoL .

Orasema festiva View in CoL ; combination by Kirby 1886: 29; Heraty 2002: 52 (taxonomy).

Diagnosis. Face flattened and smooth, with very short setae, and with a strongly impressed longitudinal groove between torulus and eye. Mesoscutal midlobe transversely costate, lateral lobe strigate ( Fig. 23 View FIGURES 22 – 25 ). Petiole without a dorsal carina, smooth and parallel-sided ( Fig. 24 View FIGURES 22 – 25 ).

Similar to O. alvarengai , which has a more finely strigate midlobe and a laterally expanded petiole.

Female. Length, 3.4–4.5 mm. Head and mesosoma metallic bluish green to purple; pedicel and anellus pale brown, flagellum dark brown; coxae yellow, metatrochanters dark brown medially; petiole black with metallic luster; gaster dorsally dark brown with metallic luster, ventrally pale brown without metallic luster, except anterior region of Ms2 black with metallic luster.

Head triangular, 1.5× as long as broad ( Fig. 22 View FIGURES 22 – 25 ). Face with broad depression enclosing longitudinal groove lateral to torulus, smooth and glossy with sparse setae; scrobal depression medially with a broad flat median carina bordered laterally by narrow foveate furrow. Eye bare. Labrum with 8 digits. Palpal formula 3-2. Pedicel as broad as F2; flagellum 2.0–2.1× height of head; F2 2.2–2.4× as long as broad, F2 1.1–1.2× as long as F3.

Mesosoma ( Fig. 23 View FIGURES 22 – 25 ). Mesoscutum with midlobe transversely costate and lateral lobe strigate with patch of fine sculpture near its center, dorsally with minute setae. Axilla obliquely strigate; mesoscutellar disc areolate-rugose, as long as broad, broadly separated from transscutal articulation at base by deep fovea; frenum areolate-rugose anteriorly. Propodeal disc areolate-rugose with irregular median longitudinal carina; callus smooth, with a few tiny setae. Fore wing 2.6× as long as broad; stigmal vein 2.0–2.5× as long as broad, slightly angled to anterior margin.

Metasoma with petiole 1.5–1.6× as long as metacoxa, 4.0× as long as broad, parallel-sided in dorsal view, dorsally smooth, without longitudinal dorsal carina ( Fig. 24 View FIGURES 22 – 25 ). Hypopygium with few minute setae apically. Ovipositor weakly curved cephalad; ventral (1st) valvula with subapical lateral line of 6–8 blunt teeth; dorsal (2nd) valvula with 8–11 rasp-like annuli meeting along midline.

Male. Unknown.
