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
