Xanthopimpla vidali Gómez sp. n.

( Figs. 2 e, 3e, 4e)

Type material. Holotype female ( UNSM): Peru, Dept. Loreto, Reserva Nacional Allpahuayo Mishana, 3°58’24 S, 73°25’45 W, 124 m, I. Gómez & Sääksjärvi leg. Malaise trap, 28.XI–4.XII.2011. Paratypes: one female ( UNSM): as above but Malaise trap, 14–20.XI.2011. One female ( ZMUT): as above but Malaise trap, 31.X–6.XI.2011.

Female ( Fig. 2 e). Head in dorsal view moderately short, with genae evenly narrowed behind eyes; frons biconcave; posterior ocellus separated from eye by 1.0 times its diameter; occipital carina complete, ventrally, laterally and dorsally expanded into a very high thin flange ( Fig. 1 b); clypeus relatively flat, basally not clearly separated from face; clypeal apex truncate; malar space about 0.3 times as long as basal mandibular width; face polished and pubescent about 1.0 times as wide as medially high.

Pronotum with apical edge reflexed and raised, overlapping propleura. Mesoscutum pubescent, with notauli strongly impressed anteriorly, bounded in front by high triangular crests; scutellum convex, with high lateral carinae. Mesopleuron polished, with ventral part densely pubescent; epicnemial carina reaching to well above level of lower corner of pronotum, ventrally strongly raised. Metapleuron weakly convex, smooth; submetapleural carina sharp but low, extending back to insertion of hind coxa. Propodeum in profile strongly declivous ( Fig. 4 e); posterior transverse carina complete and horizontal; lateromedian longitudinal carina weakly present anteriorly and not present centrally, not defining area superomedia ( Fig. 3 e); lateral longitudinal carina present, stronger above spiracle; pleural carina complete and connected to spiracle by a short carina.

Fore wing length about 10mm; areolet complete; vein Rs sinuous; cu-a opposite or slightly basal to Rs&M; discosubmarginal cell evenly, quite closely hirsute. Tergite 1 of metasoma about 1.3 times as long as posteriorly broad, with lateromedian longitudinal carina strongly developed anteriorly, anterior part of tergite 1 with strong glymma; tergite 2 about 0.6 times as long as posteriorly broad with a more or less rhombic central area. Claws of hind leg large, without a basal lobe and with four strong hairs at the base. Ovipositor sheath about 1.3–1.4 times as long as hind tibia; apex of ovipositor strongly decurved ( Fig. 2 e), with denticles on upper and lower valve.

Coloration. Pale yellow with the following areas blackish: transverse band across mesoscutum centrally, scuto-scutellar groove, anterior part of propodeum, interocellar area, dorso-lateral patches on occipital area, anterior and posterior margins of mesopleuron. Mesosternum yellowish. Tergites orange with posterior margins of tergites 1–6 yellowish. Scape yellow in frontal view and brown dorsally. Antennal flagellum brown, paler ventrally but darker apically, except apical flagellomere distally orange. Ovipositor sheath proximally yellowish, infuscate distally. Wings slightly yellowish, pterostigma yellowish.

Male. Unknown.

Diagnosis. Xanthopimpla vidali sp. n. can be distinguished from all other Neotropical species of the genus by the combination of the following characters: 1) occipital carina complete and expanded into a high thin flange; 2) propodeum with posterior transverse carina centrally horizontal; 3) ovipositor sheath long, about 1.3–1.4 times the length of the hind tibia; 4) ovipositor tip strongly decurved; and 5) mesosternum yellowish.

Biological notes. Nothing is known about the hosts of this species. This species has only been found in the Allpahuayo-Mishana National Reserve.

Etymology. This species is named after Vidal Gómez Loarte, father of the first author.

Distribution. Peru.
