Diagnosis. E. luteus sp. n. can be distinguished from all other species of the genus by the following combination of characters: 1) propodeum with complete carination (Fig. 11); 2) mesoscutum orange; 3) clypeus with a medial, apical tooth (without apical crenulations) (Fig. 7); 4) flagellum with basal four segments yellow, the rest dark brown (medial, light-coloured band absent) (Fig. 3); 5) fore wing with a well-defined dark spot apically (Fig. 3); 6) metasomal tergites completely orange (laterotergites of metasomal segments 2 and 3 brown) (Fig. 3); 7) ovipositor strongly upcurved and much shorter than length of metasoma (Fig. 3). Erythrodolius luteus sp. n. is readily distinguished from other New World species of the genus on account of its apically black spotted fore wings and almost completely orange-yellowish coloration of head, mesosoma and metasoma.
Description. Female. Fore wing length about 10 mm. Face about 2.4 times as wide as high, punctate, punctures separated by about their own diameter. Malar space about 1.0 times as high as basal width of mandible.
Clypeus with a low, rounded medial tooth (Fig. 7). Ocellar-ocular distance 2.0 times as long as maximum diameter of posterior ocellus. Antenna with 30 flagellomeres.
Mesoscutum subpolished and finely punctate, punctures in middle of lateral lobe separated by about their own diameter, posterior part of central lobe less punctate. Scutellum with lateral carinae at base only. Mesopleuron polished, ventrally with close punctures separated by about 2 times their own diameter. Metapleuron irregularly rugose ventrally, sparsely punctate dorsally, juxtacoxal carina complete (Fig. 15). Propodeum with all carinae present and strongly raised, surface impunctate and polished (Fig. 11).
Tergite 1 3.1 times as long as posteriorly wide. Tergite 2 without oblique grooves. Ovipositor straight in basal third, then strongly upcurved, about 1.0 times as long as length of hind tibia (Fig. 3).
Orange with mandibular teeth and pterostigma black; head and legs slightly more yellowish than other parts of body; apical parts of antennae (first 4 flagellomeres yellowish), ovipositor sheaths and ovipositor dark brown. 2nd and 3rd laterotergites with large rectangular brown areas. Wings more or less hyaline; fore wing with a clearly defined dark area apically; pterostigma black (Fig. 3).
Male. Unknown.
Distribution. Honduras.
Material examined. Holotype: ♀: HONDURAS: Cortés: PN Cusuco, 15.48510 °N, 88.23627 °W, 1260 ± 5m, pine-liquidambar forest, Malaise, 30.V–3.VI.2010, LLAMA #Ma-C- 06-2-01 (Longino et al. leg.) (ZMUT). Condition of type: intact except for missing right antenna beyond 5th flagellomere.
Etymology. The specific name refers to the beautiful orange-yellowish coloration of the species.
