Diagnosis. Triclistus castilloai has a similar body structure to that of T. muqui but can easily be distinguished by the planar face and black and white hind leg.

Description. F: Fore wing length 4.5–6.5 mm. Antenna with 26–30 flagellomeres, second flagellomere 2.2– 2.3x as long as centrally broad, subapical flagellomeres elongate, 1.1–1.3x as long as centrally broad, clearly longer than broad; face 1.0–1.1x as long as wide, basally flat and upper part convex; granulose with sparse puncture; clypeal margin straight; mandibles not twisted, tapered, with upper tooth broader and longer than lower tooth; labrum not exposed when mandibles closed; malar space 0.7–0.8x as long as basal mandibular width; lateral ocellus separated from compound eye by 1.2–1.7x ocellar diameter; head in dorsal view with gena slightly declivous, contiguously to the occiput carina; gena on lateral view 1.0–1.1x as long as compound eyes; frons smooth, hairless; 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; mesoscutum slightly convex anteriorly then concave posteriorly; pronotum polished with band of hairs along upper and posterior margins, mesopleurum punctate except speculum; notauli extending to center, weak; scuto-scutellar groove deep and smooth; scutellum slightly convex, with longitudinal lateral carinae reaching its end; metapleuron polished, with isolated setae in posterior area, elsewhere bare; submetapleural carina scrobiculate, anteriorly expanded into a conspicuous triangular lobe. Propodeum quite long, anteriorly weakly declivitous, posteriorly curved, with lateromedian and lateral longitudinal carinae complete, confluent area externa and dentipara smooth and punctate laterally; 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 0.6x abscissa of 2rs-m between 3rsm and 1m-cu. Metasoma with tergite I 1.5x as long as posteriorly broad, lateral longitudinal carinae more or less complete, with lateromedian carinae weak, extending 0.4x of length of tergite, sparsely punctate on basal and apical lateral margins; tergite II slightly punctate on basal and lateral margins, ca. 0.9–1.0x as long as posteriorly broad; tergite III slightly punctate on lateral margins, tergites IV–VI slightly punctate, tergites VI–VII with rows of strong setae on posterior margins.

Head extensively black except: mouth reddish brown and basal flagellomeres ventrally yellowish brown and dorsally brown. Mesosoma black except: tegula cream; mid leg with coxa apically, trochanter ventrally, femur ventrally and dorsally-apically and tibia dorsally; hind leg with coxa apically, apical half of femur, tibia dorsally, except basal 0.1, and basal half ventrally cream colored; mesotibia ventral-basally brownish. Metasoma black.

Male. Unknown

Etymology. The specific epithet castilloai is in honor of Carol Castillo, collector of the majority of species described in this article.
