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 .
