Diagnosis. Triclistus inti resembles T. megantoni sp. n. in having a complete posterior transverse carina and lacking a lateromedian longitudinal carina, as well as being predominantly black, but differs in having a smaller areolet and a predominantly cream colored metafemur.

Description. F: Fore wing length 4.5 mm. Antenna with 25 flagellomeres, second flagellomere 2.3–2.5x as long as centrally broad, subapical flagellomeres elongate 2.3x as long as centrally broad; face ca. 1.3x as long as wide, convex, slightly protuberant on 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 ca. 0.9x as long as basal mandibular width; lateral ocellus separated from compound eye by 1.1x ocellar diameter; head in dorsal view with genae evenly narrowed behind compound eyes, slightly round; gena on lateral view 1.0x as long as eye; frons smooth, punctate; crest between antennal toruli sharp; gena and vertex smooth and finely punctate. Mesosoma generally smooth, polished and finely punctate; mesoscutum convex, notauli extending to center, weak; scuto-scutellar groove deep and smooth; scutellum convex with lateral carinae reaching to 0.3x its length; pronotum polished with a band of hair along upper margin; epicnemium punctate; metapleuron polished and bare; submetapleural carina carinate, anteriorly expanded into a conspicuous triangular lobe; pleural carina curved in anterior half then 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 confluents coarsely punctate; spiracle almost round. Fore wing with 3rs-m present, petiolate above, abscissa of 2rs-m between Rs+2r and 3rs-m 0.5x abscissa of 2rs-m between 3rs-m and 1m-cu. Metasoma with tergite I 1.6x as long as posteriorly broad, lateral longitudinal carinae complete, lateromedian carinae absent, smooth and with isolated punctures; tergite II with setae on lateral margin, 0.9x as long as posteriorly broad; tergites III–V similarly sculptured, tergites VI–VII similarly sculptured but with a row of setae on posterior margin.

Head extensively black except palpi yellowish cream and scape and pedicel brownish. Mesosoma black except for tegula cream colored; legs yellowish except hind coxa, trochantellus, base of femur, apex of tibia and tarsomeres brownish. Metasoma black.

Male. Similar to female except as follows: tergite I ca. 1.5x, tergite II ca. 0.8x as long as posteriorly broad.

Etymology. The specific epithet inti is the Quechua name for the sun; according to Inca mythology, Inti is the sun god, the main deity and also known as the Giver of Life.
