Diagnosis. Anastrepha levefasciata differs from most other species of Anastrepha in having the hyaline area between the C-band and S-band extending anteriorly into cell r1, but not reaching or only very narrowly reaching the costa, and vein R2+3 sinuous. It resembles A. loewi Stone and especially A. raveni , n. sp., but differs in having longer terminalia (oviscape length greater than 8 mm vs. less than 4 mm; phallus greater than 10 mm vs. less than 5 mm) and the shape of the aculeus tip (lateral margins distinctly concave).

Description. Mostly yellow to orange, with white to pale yellow markings poorly differentiated in type specimens. Setae orange.

Head: Yellow to orange except brown ocellar tubercle. 2–3 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, 1.0–1.6 times as long as ocellar tubercle. Facial carina, in profile, straight to slightly convex dorsomedially. Antenna extended ca. 0.70–0.82 distance to ventral facial margin.

Thorax: Mostly yellow to orange, without brown markings, typical white to pale yellow areas poorly differentiated in type specimens; postpronotal lobe and scutellum entirely white. Subscutellum and mediotergite entirely orange. Mesonotum 3.40–4.12 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae yellowish. Chaetotaxy typical for genus. Katepisternal seta small and weak, barely differentiated from setulae.

Legs: Entirely yellow to orange.

Wing ( Figs. 8–9 ): Length 8.98–10.20 mm, width 3.40–3.93 mm, ratio 2.45–2.67. Apex of vein R1 at 0.60–0.65 wing length, distal to crossvein r-m. Cell c 1.00–1.14 times as long as pterostigma; pterostigma 5.00–5.24 times as long as wide. Vein R2+3 moderately to strongly sinuous. Crossvein r-m at 0.64–0.67 distance from bm-cu to dm-cu on vein M. Crossvein dm-Cu 1.30–1.43 mm long. Vein M very strongly curved apically; cell r4+5 0.50–0.67 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.50–1.58 times as long as anterior margin. Wing pattern mostly yellow to moderate orange. C-band mostly yellow to orange, dark orange in pterostigma. C-band and S-band very narrowly separated or connected along costa by hyaline band that tapers anteriorly in cell r1, barely separated from or reaching costa and apex of vein R1; broadly separated along veins R2+3 and R4+5 by hyaline band that extends to cell bm; C-band narrow and/or faint in basal part of cell r2+3. Cell dm with basal hyaline area large. S-band slender, basal half mostly pale to moderate orange, posterodistal half of area in cell cu1 slightly darker orange brown; narrow or interrupted (1 female) in cell r2+3 anterior to crossvein r-m; distal half mostly pale to moderate orange, apex in cell r4+5 usually orange brown, narrow in cells r2+3 and r4+5, at apex of vein R2+3 0.38–0.44 times width of cell r2+3, extended to or almost to apex of vein M; hyaline area proximal to apex of band extending to vein R2+3 or slightly into cell r1. V-band incomplete; proximal arm slender, diffuse, orange brown posteriorly, fading anteriorly and barely reaching vein M, absent in cell r4+5, separate from S-band anteriorly, on posterior margin with short, faint, proximal extension one-third to half distance to vein A1+Cu2; distal arm absent.

Abdomen: Mostly yellow, without brown markings.

Male terminalia: Lateral surstylus moderately long, extended beyond prensisetae by 2.0–2.5 times length of prensiseta; in lateral view (Fig. 41) slender and slightly posteriorly curved; in posterior view (Fig. 42), lateral margin concave then almost parallel-sided, apex rounded, medial margin slightly concave to slightly convex. Proctiger with ventral and lateral sclerotized areas connected. Phallus 11.0 mm long, 2.80–2.95 times as long as mesonotum; glans 0.55–0.60 mm long, ca. 0.05 times as long as phallus.

Female terminalia: Oviscape 7.09–8.54 mm long, 1.98–2.18 times as long as mesonotum, straight in lateral view, entirely yellow to orange; spiracle at basal 0.18–0.20. Eversible membrane ( Fig. 21 ) with ca. 25 strong, hooklike dorsobasal scales in 4 irregular rows in subtriangular to semicircular pattern. Aculeus ventrally curved in lateral view, 6.80–8.35 mm long, 0.95–1.00 times oviscape length; in ventral view base ( Fig. 29 ) slightly expanded, 0.21–0.23 mm wide; shaft 0.095–0.110 mm wide at midlength; tip ( Fig. 30 ) 0.26–0.34 mm long, 0.034–0.041 times aculeus length, 0.13–0.14 mm wide, 2.08–2.43 times as long as wide, lateral margin strongly convex, rapidly then gradually tapered, nonserrate, 0.08 mm wide in lateral view, 0.57–0.62 times ventral width. Spermathecae ovoid.

Distribution. Anastrepha levefasciata is known only from eastern Perú (Huánuco, Junín).

Biology. The host plants and other aspects of the biology of this species other than dates of capture of adults are unknown.

Etymology. The name of this species is an adjective formed from the Spanish leve (slight or faint) and the Latin fascia (band) in reference to the faint wing pattern.
