Xanthopimpla pucallpensis Gómez & Sääksjärvi sp. n.

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

Type material. Holotype female ( BMNH). Peru, Dept. of Ucayali, Pucallpa. J.M. Schuncke leg. 1952.

Female ( Fig. 2 d). Head in dorsal view moderately short, with genae evenly narrowed behind eyes; frons weakly biconcave; posterior ocellus separate from eye by about 0.8 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 0.2 times as long as basal mandibular width; face polished and pubescent, about 1.0 times as wide as medially high. Pronotum with apical edge strongly reflexed and raised, overlapping propleura. Mesoscutum pubescent, with notauli strongly marked anteriorly, bounded in front by high triangular crests; scutellum convex, with high lateral carinae. Mesopleuron polished, with ventral part densely pubescent; epicnemial carina reaching 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 declivous ( Fig. 4 d); posterior transverse carina complete and slightly curved; lateromedian longitudinal carina present defining area superomedia ( Fig. 3 d); lateral longitudinal carina present only anteriorly and posteriorly; pleural carina complete and connected to spiracle by a short carina. Fore wing length about 8 mm; areolet complete; vein Rs slightly sinuous; cu-a opposite Rs&M. Tergite 1 of metasoma about 1.3 times as long as posteriorly broad, with lateral longitudinal and lateromedian longitudinal carina strongly developed anteriorly; tergite 2 about 0.7 times as long as posteriorly broad, with a more or less rhombic raised central area. Claws of hind leg large, without a basal lobe and with four strong hairs in the base. Ovipositor sheath about 0.7 times as long as hind tibia; apex of ovipositor evenly tapered and decurved.

Coloration. Pale yellow with the following areas blackish: transverse band across mesoscutum centrally, scuto-scutellar groove, anterior part of propodeum, interocellar area, stripes leading from posterior ocelli to dorsolateral small patches on occipital area and patch on mesosternum. Tergites orange with posterior margins of tergites 1–5 yellowish. Scape yellow in frontal view and brown dorsally. Ovipositor sheath proximally brown, infuscate distally. Wings slightly yellowish, pterostigma yellowish.

Male. Unknown

Diagnosis. This species can be distinguished from all other Neotropical Xanthopimpla 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; and 3) propodeum with lateral carinae not present medially (not defining area dentipara). Xanthopimpla pucallpensis sp. n. resembles X. jussilai ; however, the latter has wider tergites and a wider basal area of the propodeum. In addition, the mesosternum of X. jussilai is completely black whereas in X. pucallpensis sp. n. there is only a small black mark.

Biological notes. Nothing is known about the hosts of the species.

Etymology. The specific name refers to the city of Pucallpa, Department of Ucayali, Peru.

Distribution. Peru.
