Figs 1, 15, 33
Holotype. F, PERU: La Merced, Fundo La Génova, 21.xii.2008 - 03.i.2009, trampa Malaise 2, AECID-/013484/07 (MEKRB)
Paratype. 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.
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.
