Female. ( Fig. 5 a). Head in dorsal view moderately short, with genae evenly narrowed behind eyes; frons weakly biconcave; posterior ocellus separated from eye by 0.7 times its diameter; occipital carina broadly incomplete dorsally, ventrally expanded into a flange; clypeus relatively flat, basally not clearly separated from face, but with a weak transverse groove below level of anterior tentorial pits defining a flat distal portion of the clypeus; clypeal apex truncate; malar space about 0.3 times as long as basal mandibular width; face with contiguous, coarse punctures. Pronotum with apical edge reflexed and raised. Mesoscutum polished, sparsely punctate, with notauli strongly impressed anteriorly, and bounded in front by a high triangular crests. Scutellum convex, with lateral carinae. Epicnemial carina reaching to above level of lower corner of pronotum. Metapleuron weakly convex, smooth; submetapleural carina sharp but low, extending back to the insertion of hind coxa. Propodeum in profile abruptly declivous; posterior transverse carina complete and curved; lateromedian longitudinal carina only present anteriorly so area superomedia is not defined laterally ( Fig. 6 a); lateral carina present except above spiracle; pleural carina complete, not connected to spiracle by a short carina. Fore wing length about 10 mm; Rs sinuous; cu-a opposite base of Rs&M; discosubmarginal cell evenly quite closely hirsute. Metasoma with tergite 1 about 1.2–1.3 times as long as posteriorly broad, with well-developed lateral carina anteriorly; tergite 2 about 0.6 times as long as posteriorly broad with a more or less rhombic raised central area which is polished and sparsely punctate laterally. Ovipositor sheath 0.5–0.6 times as long as hind tibia; apex of ovipositor evenly tapered, slightly decurved with denticles on both valves.

Coloration. Yellow with the following areas blackish: transverse band centrally across mesoscutum, scutoscutellar groove, anterior part of propodeum; interocellar area, triangular marks on back of head, posterior part of tegula. Anterior and posterior margins of mesopleuron narrowly infuscate; hind coxa ventrally black marked; ovipositor sheath proximally yellowish, strongly infuscate distally. Wings slightly yellowish, pterostigma brownish.

Male: Similar to female.

Diagnosis. This species can be distinguished from all other Neotropical species of Xanthopimpla by the combination of the following characters: 1) metasoma and hind leg without black marks; 2) propodeum with anterior transverse carina absent centrally; 3) lateromedian longitudinal carinae only present anteriorly (area superomedia not defined laterally); 4) ovipositor sheath about 0.5–0.6 times as long as hind tibia, yellowish but apically infuscate; and 5) occipital carina dorsally absent. Xanthopimpla allpahuaya sp. n. resembles X. aurita especially in propodeal carination. However, this new species has a longer tergite 1, has no black marks on the metasoma and the ovipositor sheath is about half the length of that of X. aurita .

Biological notes. This species appears to be restricted to highly vulnerable white sand rain forests (varillal forests).

Etymology. The specific name refers to the Allpahuayo-Mishana National Reserve, Department of Loreto, Peru, the principal Peruvian fieldwork area of the first and second authors. This species is named in honour of this unique area of Peruvian Amazonia.

Distribution. Brazil, Ecuador, Peru.
