Diagnosis. Triclistus warmi structurally is close to T. yungas sp. nov., but can be differenciate by the petiole longer than wide, face 1.4x as long as wide and hind femur brown in T. warmi .

Description. F: Fore-wing length 3.5 mm. Antenna with 22 flagellomeres, second flagellomere ca. 2.0x as long as centrally broad, subapical flagellomeres elongate, ca. 1.7x as long as centrally broad, clearly longer than broad; face ca. 1.4x as long as wide, granulose with sparse punctures; clypeal margin straight; mandibles not twisted, tapered, with upper tooth broader and longer than lower tooth; labrum not exposed when mandibles closed; malar space ca. 0.8x as long as basal mandibular width; lateral ocellus separated from compound eye by ca. 1.4x ocellar diameter; head in dorsal view with genae slightly declivitous, contiguously to the occiput carina; gena on lateral view ca. 1.5x as long as eyes; frons smooth, punctate; crest between antennal toruli sharp; gena predominately punctate except for mid-posterior area glabrous; vertex punctate except for glabrous triangular area around occipital carina. Mesosoma generally smooth, polished and punctate; pronotum polished with band of setae along upper and posterior margins, mesopleurum punctate except speculum; mesoscutum slightly convex; notauli extending to center, weak; scuto-scutellar groove deep and smooth; scutellum slightly convex, with longitudinal lateral carinae reaching to its end; metapleuron polished; submetapleural carina scrobiculate, anteriorly expanded into a conspicuous triangular lobe. Propodeum quite long, anteriorly weakly declivous, posteriorly curved, with lateromedian and lateral longitudinal carinae complete, confluent area externa and dentipara smooth and punctate; area spiracularis + area lateralis confluent, coarsely punctate; spiracle oval.

Fore wing with 3rs-m present, abscissa of 2rs-m between Rs+2r and 3rs-m 0.5x abscissa of 2rs-m between 3rsm and 1m-cu. Metasoma with tergite I ca. 1.5x as long as posteriorly broad, lateral longitudinal carinae more or less complete, with lateromedian carinae weak, extending ca. 0.4x of length of tergite, sparsely punctate on basal and apical lateral margins; tergite II slightly punctate on lateral margins, ca. 0.9x as long as posteriorly broad; tergites III-VI slightly punctate on lateral margins, tergites VI-VII with rows of strong setae on posterior margins.

Head extensive black except mouth yellowish brown and basal flagellomeres ventrally yellowish brown and dorsally brown. Mesosoma black except tegula yellowish brown; leg reddish brown except dorsally hind femur brown. Metasoma black with tergites apically reddish brown.

Male. Unknown

Etymology. “ Warmi ” is the Quechua word for woman.
