Holotype. F, PERU: CU, Qosňipata [valley], San Pedro, 13o03’22.5”S / 71o32’55.2”W, 1520 m, 22.ix.2007, Malaise trap, C. Castillo Leg. ( MUSM).

Diagnosis. Triclistus muqui resembles T. castilloai sp. nov. in having the mesosoma depressed and the mesoscutum slightly convex, but can be distinguished by the distinctly concave face.

Description. F: Fore wing length 3.8 mm. Antenna with 20 flagellomeres, second flagellomere ca. 1.8x as long as centrally broad, subapical flagellomeres elongate, ca. 1.3x as long as centrally broad; face with upper part weakly declivous and rounded after that concavity, ca. 1.0x as long as wide, granulose punctate; clypeal margin convex; mandibles with upper margin following shape of clypeal margin, slightly up-curved, tapered, with upper tooth broader and longer than lower tooth; labrum not exposed when mandibles closed; malar space ca. 0.6x as long as basal mandibular width; lateral ocellus separated from compound eye by ca. 2.0x ocellar diameter; genae slightly declivous, with upper part of gena slightly concave; frons smooth, hairless; crest between antennal toruli sharp; gena on lateral view ca. 1.5x as long as eyes; gena predominately punctate except for mid-posterior area glabrous; vertex punctate except for glabrous triangular area around occipital carina. Mesosoma generally smooth, polished and sparsely punctate; mesoscutum slightly convex anteriorly then concave posteriorly; notauli extending to center, weak; scuto-scutellar groove deep and smooth; scutellum plane, with longitudinal lateral carinae reaching 2/ 3x its length; pronotum polished with band of hair along upper and posterior margins, mesopleurum punctate except speculum; metapleuron polished, with isolated setae; 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, joining 2rs-m in middle. Metasoma with tergite I ca. 1.3x as long as posteriorly broad, lateral longitudinal carinae more or less complete, with lateromedian carinae extending ca. 0.4x of length of tergite, sparsely punctate on lateral margins; tergite II slightly punctate on lateral margins, ca. 0.7x as long as posteriorly broad; tergites III– V slightly punctate on lateral margins, tergites VI–VII similarly sculptured but with row of strong setae on posterior margins.

Head extensively black except mouth parts yellowish brown, antenna basally yellowish brown darkening apically, mandibles basally reddish brown. Mesosoma black except for reddish brown tegula; fore legs reddish brown; mid and hind leg blackish brown. Wings slightly infuscate; pterostigma brown. Metasoma dark brown. Male. Unknown

Etymology. The specific epithet is based on “ muqui ”, the name of a mythological elf from the central Andes in Bolivia, Peru, Ecuador and Colombia, which dwells inside mines.
