Diagnosis
Diagnosis. Male: head longer than wide; malar area as long as 1 / 3 of mandibular width; clypeus projecting about 2 / 3 of its total length below the lower tangent of compound eyes; surface between compound eye and lateral ocelli slightly concave; vertex slightly expanded behind ocelli; metapostnotum with dense granulation and one unique, coarse carina medially; metasomal terga amber with metallic green bands; T 1 –T 4 with fine punctures, separated by 1–2 puncture widths in central area, surface between punctures microreticulate.
Description
Description.Male. Size. Total body length 7 mm; forewing length 1.47–1.48 mm. Structure. Head longer than wide, head length to width ratio 1.06; malar area as long as 1 / 3 of mandibular width; mandible simple; labral distal process in the form of a minute inverted triangle; epistomal sulcus obtuse and slightly rounded; clypeus projecting about 2 / 3 of its length below lower tangent of compound eyes; compound eyes emarginated above level of antennal torulus; surface between compound eye and lateral ocellus slightly concave; vertex slightly expanded behind ocelli; preoccipital ridge rounded; antennal flagellum weakly sinuate, F 2 slightly more than 2 x length of F 1; pronotal lateral angle obtuse; anterior border of mesoscutum rounded; metapostnotum about 1.3x length of metanotum medially; legs unmodified; metabasitibial plate rounded, margin weakly defined, flat; S 4 and S 5 unmodified; gradulus of S 6 greatly invaginated medially, covered by membrane, pygidial plate large with widely rounded margin; S 7 with median apical process short, without setae; median apical process of S 8 broad with apical margin bearing lateral peaks, without setae, separated by weak concavity, but apical edge of S 8 with lateral lobes extending ventrally separated by a thin and slightly elongate medial surface in posterior view. Genitalia. Gonobase. Length nearly 1 / 3 that of gonocoxite. Gonocoxite. Outer margins slightly convex apically, surface smooth; basal portion of inner dorsal margins parallel with large and rectangular excavated area; apical portion of inner dorsal margins strongly concave. Gonostylus. Basal region with rvl membranous, short, about ½ of length of gonocoxite, rounded apically, with a few short setae at extremity and band of short setae on inner margin of dorsal surface; mgl a crescent-shaped lobe with scattered short setae; ogp large and nearly entirely membranous, ending before mgl, with many long setae near apex and free margin extending to ventral region; clump of short setae at base of ogp. Penis valve. Rounded in lateral view; main dorsal ridge central; apex narrow and parallel-sided, pointed at apex; outer lateral expansion with extremity bilobed, outer lamella lobed; ventral surface with prong narrow and parallelsided, slightly pointed at apex, extending past volsella posteriorly. Volsella. Inner apical corner rounded; medioapical margin convex. Sculpture. Upper paraocular area and frons densely punctuate, with very fine, contiguous punctures and scattered coarser setal bases intermixed, surface finely and irregularly roughened; lower paraocular area with coarse oblique punctures separated by 1–2 puncture widths, surface between punctures microreticulate; supraclypeal area with punctures finer than those of lower paraocular area and irregular in spacing in lower half, surface between punctures strongly microreticulate; clypeus with coarse punctures separated by 1–3 puncture widths, surface between punctures strongly microreticulate; mesoscutum densely punctuate, with fine, contiguous punctures that becoming oblique in central region, and coarser setal bases intermixed more concentrated on laterals; mesoscutellum with fine punctures irregular in size and spacing, surface between punctures smooth; metanotum more densely punctate than mesoscutellum, posterior margin roughened, surface between punctures smooth and shiny; mesepisternum and metepisternum densely punctate, with fine, contiguous punctures and several scattered coarser setal bases intermixed; dorsal surface of metapostnotum with triangular area defined by denser granulation than elsewhere, punctures fine and oblique, and with one unique, coarse carina not reaching edge medially; propodeal lateral and posterior surfaces microareolate, and scattered coarser setal bases intermixed, surfaces microstriate; dorsal surface of T 1 –T 4 with fine punctures, separated by 1–2 puncture widths in central area, surface between punctures microreticulate. Color. Bright green, except: mandible brown with reddish apex; about apical third of clypeus with yellow transverse band, sometimes small triangular area medially in its upper margin; labral basal process yellow; labral distal process brown; scape, pedicel and flagellum dark brown, flagellum much lighter below than above, sometimes nearly yellow; legs brown, coxae and femora with faint metallic green highlights, inner surface of protibia yellowish; inner surface of meso- and metatarsus light brown; T 1 –T 2 brown with metallic green highlights, posterior marginal zones amber, T 3 –T 5 amber with bands medially or only disc brown with faint metallic green highlights; sterna amber, except S 1 with green highlights; pygidial plate yellow. Pubescence. Dorsal surface with very short, fine, plumose whitish setae; long, simple or branched, white or light brown setae on nearly all body parts. Compound eyes with brown and long setae, longer than ocellar diameter; strip of short, plumose white setae along inner margin of compound eye; triangular area of metapostnotum without setae.

Materials Examined
Material examined. Holotype, male, PERU: Ancash: vicinity Carhuaz, 15.v. 1996 (J.G.Rozen & A.Ugarte) (AMNH). Paratype, PERU: Ancash: 1 male, vicinity Carhuaz, 15.v. 1996 (J.G.Rozen & A.Ugarte) (MPEG). Etmology. The specific epithet honors the Incan Civilization that once lived widely in the Andean region, but particularly within Peru.The name is treated as a noun in apposition.
