Holotype. ♁, “ EcUADOR: Pich \ above Tandapi , 8 Feb.\ 1983, 2300m, Masner \ Sharkey ” ( SEMC).

Paratypes. 1♀, 2♁♁, with same label data as holotype ( SEMC) ; 1♁ ♀, with same label data as holotype ( MZSP) ; 1♀, “ EcUADOR, Imbaura :\ N. Perucho near\ Otavalo, I-7-1971 \ 2000 m., L. Pena ” ( SEMC) .

Diagnosis. Both sexes with preoccipital ridge carinate; female metabasitibial plate well rimmed; female metapostnotum with striations not reaching the posterior margin; male face concave above the antennal alveolus with a stripe of short, strongly plumose setae; medioapical margin of metasomal sternum III not notched; apical margin of metasomal sternum IV straight, subapical margin with pubescence distributed as on metasomal sternum III, lateral projections, including setae, as long as sternum.

Description. Female: Total body length 5.95 mm; forewing length 4.6 mm; distance between compound eye notches 1.17 mm; maximum head length 1.55 mm; intertegular distance 1.2 mm. Head rounded (Fig. 2); mandible with weak subapical tooth; malar space very short, less than basal mandibular width; compound eyes with minute setae; preoccipital ridge carinate. Mesoscutum anterior border slightly acuminate. Inner metatibial spur pectinate, with three branches excluding apical portion of rachis. Forewing with 1m-cu confluent with 1rs-m; maximal length of third

submarginal cell less than two times maximal length of second submarginal cell. Metapostnotum as long as mesoscutellum, broadly rounded posteriorly. Metasoma broadly rounded; terga not depressed; sterna unmodified.

Head punctate, punctures contiguous in upper parocular area and on frons, imbricate microreticulations evident. Mesoscutum granular, punctures irregularly distributed with microreticulations evident among punctures. Mesepisternum more granular than mesoscutum. Metapostnotal striations irregular, extending to two-thirds length, remainder of surface strongly imbricate (Fig. 4). Terga lineolate with small punctures, those on terga III–V with greater diameter.

Integument of head and mesosoma brilliant metallic green with some dull blue reflections. Mandible, labrum, malar space, and apical one-half of clypeus dark brown; antenna, all leg podites, tegula, and sterna light brown. Wing veins brown; membrane lightly fuscous. Terga mostly brilliant metallic green with some dark brown areas on median surface of discs, apical marginal areas blending to translucent brown.

Pubescence on head, mesosoma, and metasomal sterna pale yellow; setae on legs dark amber, on terga light amber; setae short on terga, long and erect on sterna; sternum II with long setae with recurved apices.

Male: as described for female except as following: Total body length 5.82 mm; forewing length 4.4 mm; distance between compound eye notches 1.1 mm; maximum head length 1.62 mm; intertegular distance 1.0 mm. Head longer than wide (Fig. 6); surface between supraclypeal area and frons depressed. Mesoscutal median line well impressed. Metapostnotum longer than mesoscutellum, with depressed striate surface. Metasomal sternum IV with lateral projections longer than sternum length (Fig. 8); metasomal sternum VI strongly emarginate; metasomal sterna VII and VIII as depicted in Figure 10; genital capsule as depicted in Figure 12.

Clypeus and supraclypeal area with few punctures, without evident microreticulations. Mesoscutum sparsely punctate, punctures fine and separated by more than three times a puncture diameter. Metapostnotal striae mostly longitudinally oriented, forming a triangle of ornamentation, not reaching posterior border, especially at corners. Terga finely punctate.

Integument of head and mesosoma brilliant metallic green with some blue reflections. Apical border of clypeus yellow. Coxae to femora with metallic highlights, tibiae brown, remaining podites light brown. Metasoma entirely dark brown.

Depressed surface of head with short, dense, plumose setae. Projection of metasomal sternum IV bearing long setae, apical margin not bearing short specialized setae. Genital capsule pubescence as depicted in Figure 12.

Etymology. The specific epithet is a noun in apposition and honors the Native American language Quichua, still spoken today in the Andes.
