- Xanthopimpla amazonica sp. n. Gómez, Sääksjärvi & Veijalainen urn:lsid:zoobank.org:act: 00D140B4-5471-43A4-8179-3DE3F0506ABD Type material. Holotype female (ZMUT): Peru, Dept. of Madre de Dios, Concesión para la conservación Los Amigos, 12°34’07” S, 70°05’57” W, 240 m elev., Isrrael Gómez leg. Malaise trap, 17-21.VIII.2008. Female (Fig.1). Head in dorsal view moderately short, with genae evenly narrowed behind eyes; frons weakly biconcave; posterior ocellus separate from eye by 0.8-0.9 times its own diameter; occipital carina complete, ventrally, laterally and dorsally expanded into a very high membranous flange (Fig. 4); clypeus relatively flat, basally not clearly separated from face; clypeal apex truncate; malar space 0.3 times as long as basal mandibular width; face polished and pubescent, about 0.8 times as wide as medially high. Pronotum with apical edge strongly reflexed and raised, overlapping propleuron. Mesoscutum pubescent, with notauli strongly impressed anteriorly, bounded in front by high triangular crests (Figs 8, 9); scutellum convex, laterally with high carinae. Mesopleuron polished, centrally almost bare with ventral part densely pubescent; epicnemial carina reaching well above level of lower corner of pronotum. Metapleuron weakly convex, smooth and almost bare; submetapleural carina sharp but low, extending back to insertion of hind coxa. Propodeum in profile abruptly declivous (Fig. 3); anterior transverse carina present except centrally, where it is curved forward joining lateromedian longitudinal carina (Fig. 2); posterior transverse carina complete and medially clearly bowed downwards; lateromedian longitudinal carina present an- teriorly but not clearly defining area superomedia; lateral longitudinal carina present anteriorly and posteriorly but not defining area dentipara, lateral carina stronger above spiracle (Fig. 3); area petiolaris divided longitudinally by weak central carina; pleural carina complete. Fore wing length 10-12mm; areolet complete; vein Rs sinuous; cu-a opposite base of Rs&M; discosubmarginal cell evenly, quite closely hirsute. Tergite 1 of metasoma about 1.3 times as long as posteriorly broad, with lateral longitudinal and lateromedian longitudinal carinae developed strongly anteriorly, anterior part of tergite 1 with strong glymma; tergite 2 with a more or less rhombic, raised central area. Hind tibia with five bristles near the apex; fourth tarsomere about 0.9 times as long as broad. Claws of hind leg large, without a basal lobe and with four strong hairs at the base, three of them exceeding the tip of the claw. Ovipositor sheath about 0.8 to 0.9 times as long as hind tibia (Fig.1); apex of ovipositor evenly tapered, slightly decurved with denticles on upper valve. A bright yellow species with transverse black bands across the mesoscutum centrally, the region of the scuto-scutellar groove, and the anterior part of the propodeum. Interocellar area, small triangular marks on back of head, anterior and posterior margin of mesopleuron and entire mesosternum also black. Tergites orange and with small dark brown punctures posteriorly, anterior part of tergites 1-4 brownish, posterior margins of tergites 1-3 yellowish. Ovipositor sheath generally proximally yellowish, infuscate distally. Antenna with scape yellow ventrally, brownish dorsally, with blackish spot on inner margin. Wings slightly yellowish, pterostigma yellowish. Male. Unknown. Diagnosis. This species can be distinguished from all other Neotropical species of the genus by a combination of the following characters: occipital carina forming a vertical flange, propodeum with posterior transverse carina medially clearly bowed downwards, lateral longitudinal carina present only anteriorly and posteriorly, not defining area dentipara, and petiolar area with longitudinal carina. Biological notes. Nothing is known about the hosts of this species. Etymology. The name of the species refers to the vast lowland rainforest area of Amazonia, which seems to support most of the Neotropical Xanthopimpla species. Many new species of the genus are to be described in the future when Amazonian rainforest habitats become better sampled.
