Triclistus cholo resembles T. pailas in having the posterior transverse carina complete and the mesosoma reddish and metasoma black, but T. cholo differs in the reddish and hairless metapleuron, and the submetapleural carina smooth, without a series of pits. FIGURE 4 Lateral habitus of Triclistus cholo sp. n. paratype female Description. F: Fore wing length 4.2–5.2 mm . Antenna with 24-26 flagellomeres, second flagellomere 2.3– 2.5x as long as centrally broad, subapical flagellomeres elongate 1.4–1.6x as long as centrally broad; face 1.2– 1.3x as long as wide, convex, slightly protuberant on the clypeus area, granulose with sparse punctures; mandibles not twisted, tapered, with upper tooth broader and longer than lower tooth; labrum not exposed when mandibles closed; clypeal margin straight; malar space 0.7–0.9x as long as basal mandibular width; lateral ocellus separated from compound eye by 1.0–1.2x ocellar diameter; head in dorsal view with gena evenly narrowed behind compound eyes, round; gena on lateral view 0.9–1.1x as long as compound eye; frons smooth, slightly punctate; crest between antennal toruli sharp; gena and vertex smooth and punctate. Mesosoma generally smooth, polished and finely punctate; mesoscutum convex; notauli extending to center, weak; pronotum polished, with a band of hair along upper margin; scuto-scutellar groove deep and smooth; scutellum convex, with lateral carinae reaching end; mesopleuron punctate on upper, anterior and lower margins; upper part of epicnemium punctate; metapleuron polished and bare; submetapleural carina smooth, anteriorly expanded into a conspicuous triangular lobe; pleural carina curved in anterior half them declivitous. Propodeum quite short and evenly declivitous; without lateromedian longitudinal carinae thus with all areas confluent, smooth but punctate on lateral margins; posterior transverse carina present; area spiracularis + area lateralis confluent, coarsely punctate; spiracle round. Fore wing with 3rs-m present, sometimes weak, joining 2rs-m in the middle. Metasoma with tergite I 1. 6–1.7x as long as posteriorly broad, lateral longitudinal carinae reaching to spiracle, lateromedian carinae absent, smooth and with isolated punctures; tergite II similarly sculptured, 0.8– 0.9x as long as posteriorly broad; tergites III–V similarly sculptured, tergites VI–VII similarly sculptured but with rows of setae on posterior margins. Head extensively black except palpi yellowish cream and scape and pedicel brownish. Mesosoma reddish brown, area petiolaris + posteroexterna brownish; legs yellowish except hind coxa, trochantellus, base of femur, apice of tibia and tarsomeres brownish. Metasoma black. Male. Similar to female except tergite I 1.3x as long as posteriorly broad. Etymology. The specific epithet is in reference to the term “ cholo ”, usually a pejorative used in some countries of Latin America , but in Peru is used by many as an affectionate way of referring to a fellow, so Peruvians identify themselves as “cholos”. The name is considered a noun in apposition.
