Diagnosis. This species is easily distinguished from all other species of Trupanea by its banded wing pattern and the nonmicrotrichose areas on the scutum and scutellum.
Description. Small, body length 3 mm in male. Wing length 3.2 mm.
Head (Figs. 9–10): Yellow to orange except ocellar tubercle and most of occiput bluish gray; mostly microtrichose. Frons nonsetulose medially; lateral margins and medial vitta grayish microtrichose; with 2 broad submedial vittae orange, nonmicrotrichose. 3–4 frontal setae brown, acuminate, longest (posterior) seta ca. half width of frons at level of seta; 2 reclinate orbital setae, anterior seta brown, acuminate, posterior setae short, white, slightly lanceolate; ocellar seta well developed, ca. half width of frons at level of anterior ocellus; postocellar, lateral vertical, and postocular setae, and most setulae on postgena white, lanceolate; facial ridge setulae brown acuminate; genal setulae mostly yellow or brown, acuminate. Antenna mostly red brown; arista minutely pubescent. Palpus relatively slender, ventroapical third brown.
Thorax (Fig.16): Mostly dark brown and moderately densely microtrichose giving bluish gray appearance. Postpronotal lobe partly orange. Scutum medially with microtrichose vitta that is brown medially and gray laterally, narrowing posterior to transverse suture and ending midway between acrostichal seta and posterior margin; with 2 nonmicrotrichose dorsocentral vittae, very narrow anterior to transverse suture and not extended to anterior margin of scutum, broadening posteriorly, extended laterally to intra-alar seta and medially including acrostichal seta, narrowly connected at posterior margin; microtrichia bordering and aligned with bare vitta anterior to transverse suture brown; laterally microtrichia gray. Scutellum shiny, nonmicrotrichose except for small lateral area ventral to basal scutellar seta; nonsetulose except for a few pale brown setulae on lateral microtrichose area. Scutal setulae white, slightly lanceolate, in 4 rows; 2 submedial rows 2–4 setulae wide, on gray lateral part of medial microtrichose vitta; 2 lateral rows 4–5 setulae wide, narrowing posterior to transverse suture (possibly some abraded in holotype). Thoracic setae relatively long; basal scutellar seta more than 3 times as long as scutellum. 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, pale brown, slightly lanceolate. Pleuron entirely microtrichose; mediotergite with broad medial nonmicrotrichose shiny area. Setulae on postpronotal lobe, propleuron, anepisternum, katepisternum, and anepimeron white, lanceolate.
Legs: Femora and tibiae mostly dark brown; tarsi yellow. Male fore tibia and tarsus (Fig. 22) with most dorsal setulae erect. Male fore basitarsus 2.3 times as long as high (measured on medial side), 2 times height of tibia apically; subbasally with 2 posteroventral setae, slightly longer than height of basitarsus, projecting perpendicularly, and with 3–5 anteroventral setae, almost as long as basitarsus, projecting obliquely. Mid femur with anterior row of brown setae on basal half, larger and more perpendicular than setulae; in male with row of well developed brown anteroventral setae on distal half.
Wing (Fig. 4): Crossvein r-m at 0.74 distance from bm-cu to dm-cu on vein M. Veins R2+3 and R4+5 without setulae dorsally or ventrally. Pattern comprising 5 brown bands: one broadly covering all of basal cells, narrowing in basal half of cell cu1 where it connects to narrow band extending from pterostigma to posterior margin in cell cu1; latter band connected in cell br to third band that covers crossveins r-m and dm-cu and extends to posterior wing margin; third band connected anteriorly in cells r1 and r2+3 to pair of subapical bands, which connect anteriorly, fork in middle of cell r4+5, and reach posterior wing margin in cell m, the more distal band covering apex of vein M. Also with following hyaline areas: band from anterior margin in distal fourth of cell c extended to vein Cu1; subtriangular marginal mark in cell r1 distal to apex of vein R1, extended to vein R4+5; apical mark from midway between apices of veins R2+3 and R4+5 almost to apex of vein M; 2 elongate marks across cell m, subbasal band extended anteriorly to vein R4+5, subapical band extended to middle of cell r4+5; elongate mark across distal part of cell cu1, extended anteriorly almost to vein M; anal lobe and small marginal area basally in cell cu1; and alula.
Abdomen: Tergites entirely dark brown, mostly shiny nonmicrotrichose except base of syntergite 1+2. Setulae pale brown, acuminate.
Male terminalia (Figs. 29–30): Epandrium and surstyli ovoid in posterior view; lateral surstylus short, strongly medially curved, blunt apically, in lateral view with well developed dorsal lobe; medial surstylus short, with prensisetae well separated, medial prensiseta slightly broader than lateral prensiseta. Glans membranous except for projecting, hooklike sclerite near base.
Biology. Nothing is known of the host plants or other aspects of the biology of this species.
Distribution. Trupanea fasciata is known only from the type locality in the mountains of Jujuy, Argentina.
Type data. Holotype ♀ (CNC, USNMENT 00744480), ARGENTINA: Jujuy: Barrios S. La Quiaca, 3500 m, 31 Oct 1968, L. E. Peña.
Etymology. The name of this species is a Latin adjective referring to the banded wing pattern.
