F, same data ( MEKRB ); F same data, except 25.x-08.xi.2008 ( MUSM ). Diagnosis. Triclistus ashaninka has a body structure similar to the Costa Rican species T. slimellus Gauld & Sithole and T. tabetus Gauld & Sithole , as well as T. matsiguenga sp. n. , but it is distinctive among them for having the face concave. Description. F: Fore wing length 3.9–4.2 mm . Antenna with 20 flagellomeres, second flagellomere 2.0x as long as centrally broad, subapical flagellomeres elongate, 1.5x as long as centrally broad, clearly longer than broad; face concave, 1.1x as long as wide, granulose with sparse punctures; clypeal margin concave; labrum exposed when mandibles closed, punctate; mandible with upper margin following labrum’s shape, not twisted, tapered, with upper tooth broader and longer than lower tooth; malar space 1.1x as long as basal mandibular width; lateral ocellus separated from compound eye by 1.8x ocellar diameter; head in dorsal view with gena slightly declivous then abruptly rounded; gena, on lateral view 1.0x as long as compound eyes; frons coarsely punctate; crest between antennal toruli wide; upper part of gena and vertex smooth and bare except for row of punctures around compound eyes; lower part of gena punctate. Mesosoma generally smooth, polished and coarsely punctate; pronotum polished with band of hairs along upper and posterior margins, mesopleurum punctate except speculum; mesoscutum slightly convex in anterior half then slightly concave in posterior half; notauli extending to center, weak; scutoscutellar groove deep and smooth; scutellum slightly convex with longitudinal lateral carinae reaching to 0.4x its length; metapleuron polished with isolated setae in anterior area, elsewhere bare, with posterior upper corner (intersection between submetapleural and pleural carinae) forming almost a right angle; submetapleural carina smooth, anteriorly expanded into a conspicuous triangular lobe. Propodeum quite long and straight, rather flat then abruptly rounded posteriorly; with longitudinal carinae, confluent area externa and dentipara smooth and punctate laterally; posterior transverse carina strong; area spiracularis + area lateralis confluent, coarsely punctate; spiracle oval. Fore wing 3rs-m absent, areolet not defined. Metasoma with tergite I 1.8x as long as posteriorly broad, lateral longitudinal carinae reaching to spiracle, with lateromedian carinae extending 0.6–0.7x length of tergite, coarsely punctate between carinae; tergite II coarsely punctate on lateral margin areas, as long as posteriorly broad; tergites III–V coarsely punctate, tergites VI–VII similarly sculptured but with rows of strong setae on posterior margins. FIGURES 1 Lateral habitus of Triclistus ashaninka sp. n. , holotype female Head extensively black except mouth parts, malar space and mandibles and antennae yellowish brown; antennomeres with darker tips. Mesosoma black except the following: tegula yellowish; fore legs reddish; mid leg reddish except femur brown; hind leg with trochanter, trochantellus, basal 1/3 of tibia and basal half of first tarsomere creamish, remainder reddish brown. Wings hyaline; pterostigma brown. Metasoma black. Male. Unknown Etymology. The specific epithet “ ashaninka ” is in honor of the Asháninka , the largest indigenous group of Peru ; they live scattered over a vast territory that includes the valleys of the Apurimac, Ene, Tambo, Perene Pichis, a sector of Upper Ucayali and Gran Pajonal interfluvial area, and this species was collected in their territory.
