Diagnosis. This species is distinguished from all other species of Trupanea by the brown pattern on the basal half of the wing, which covers cells bm and bcu, the pterostigma, crossvein r-m, and the areas between them except for a large ovoid hyaline spot in cells br and dm, and the largely nonmicrotrichose abdomen. In T. lilloi Aczél , the species with perhaps the most similar wing pattern, there is no large hyaline spot in cells br and dm, and there is a narrow ray to the apex of vein R2+3, bordered by an apical hyaline spot in cell r2+3.

Description. Small, body length 3.5–4.0 mm in female. Wing length 3.7–4.0 mm in female.

Head ( Figs. 11–12 ): Yellow to orange except ocellar tubercle and most of occiput bluish gray, and face broadly brown dorsally; entirely microtrichose. Frons nonsetulose medially; lateral margins grayish; medially broadly orange. Frontal setae brown, acuminate, in female with 4–5 setae, moderately long, longest slightly more than half width of frons; with 2 reclinate orbital setae, anterior seta brown, acuminate, posterior seta short, white, slightly lanceolate; ocellar seta well developed, 0.6–0.7 times width of frons at level of anterior ocellus in female; postocellar, lateral vertical, and postocular setae, and most setulae on postgena white, lanceolate; setulae on facial ridge and anteriorly on gena brown, acuminate. Antenna mostly red brown to dark brown, apex of pedicel and sometimes base of first flagellomere orange; arista minutely pubescent. Palpus relatively slender, entirely yellow.

Thorax ( Fig. 17 ): Mostly dark brown and densely microtrichose giving bluish gray appearance. Postpronotal lobe and notopleuron partly orange. Scutum without vittae. Following setae well developed, brown, acuminate: postpronotal, anterior notopleural, presutural and postsutural supra-alar, intra-alar, postalar, dorsocentral (aligned very close to transverse suture), acrostichal, 1 (basal) scutellar, 1 anepisternal, anepimeral and katepisternal. Posterior notopleural seta short, white, lanceolate. Scutal setulae evenly distributed, mostly white lanceolate, posterior to acrostichal setae predominantly brownish, acuminate. Scutellum nonsetulose medially; with mostly brownish, acuminate setulae on lateral and apical margins. Setulae on postpronotal lobe, propleuron, and most of anepisternum white, lanceolate. Posteriorly on anepisternum, dorsally on katepisternum, and on anepimeron mixed with brownish, acuminate setulae.

Legs: Femora and mid and hind tibiae mostly dark brown; fore tibia, except sometimes basally, and tarsi yellow. Mid femur with anterior row of brown setae on basal two-thirds, slightly larger and more perpendicular than setulae.

Wing ( Fig. 5 ): Crossvein r-m at 0.71–0.73 distance from bm-cu to dm-cu on vein M. Veins R2+3 and R4+5 without setulae dorsally or ventrally. Pattern including very pale brown cell bc and base of cells c and br, and extensive, dark brown markings, all connected: large mark including pterostigma, cells bm and bcu, anterior basal half of cell cu1, crossvein r-m, and all of the area between them except for a large ovoid hyaline spot in cells br and dm; cells r1 and r2+3 dark brown except for 1 marginal hyaline band distal to apex of vein R1 and aligned with or slightly proximal to r-m, extended midway across cell r2+3, 1 ovoid or quadrate marginal hyaline spot near midpoint between apices of R1 and R2+3, extended to or almost to R2+3, 1 ovoid or quadrate marginal hyaline spot distal to apex of R2+3, extended no more than halfway to R4+5, and in Bolivian specimens, 1 small, crescent shaped marginal hyaline spot near apex of r2+3; cell r4+5 brown except for 1 large ovoid subbasal hyaline spot, sometimes ( Argentine specimen) 1 small medial ovoid hyaline spot slightly proximal to midlength of cell, small extension of distal hyaline mark of cell m, and narrow apical marginal hyaline band or pair of spots; posterodistal half of wing with 4 brown rays extending to posterior margin, 1 subapically in cells dm and cu1, 1 covering crossvein dm-cu and apex of vein Cu1, and 2 in cell m.

Abdomen ( Fig. 27 ): Tergites entirely dark brown; mostly shiny, nonmicrotrichose; gray microtrichose on most of syntergite 1+2, except posterolateral margin, and narrowly medially on tergite 3. Setulae mostly brown, acuminate; white, lanceolate basolaterally on syntergite 1+2.

Female terminalia: Oviscape in ventral view ca. 1 mm long, 0.75 times length of thorax; in dorsal view equal to length of tergites 4–6; entirely dark brown, shiny, nonmicrotrichose; setulae brown, acuminate. Aculeus ( Fig. 28 ) well sclerotized, relatively broad, tapering evenly to triangular apex.

Biology. Nothing is known of the host plants or other aspects of the biology of this species.

Distribution. T. polita is known from highland areas (3700–3820 m) of Jujuy, Argentina and Cochabamba, Bolivia.

Type data. Holotype ♀ ( MNKM USNMENT 00055986), BOLIVIA: Cochabamba: Pongo, 5 km. W of, 17°42.9'S 66°36'W, 3820 m, 23 Mar 2001, A. Freidberg. Paratypes: ARGENTINA: Jujuy: Santa Catalina, 3700 m, 25 Oct 1968, L. E. Peña, 1♀ ( CNC). BOLIVIA: Cochabamba: Pongo, 5 km. W of, 17°42.9'S 66°36'W, 3820 m, 23 Mar 2001, A. Freidberg, 1♀ ( USNM, USNMENT 00056032).

Etymology. The name of this species is a Latin adjective referring to the extensive shiny, nonmicrotrichose area on the abdomen.
