Diagnosis. Anastrepha raveni 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. levefasciata , n. sp., but differs from the former in having a narrower aculeus tip and lacking the distal arm of the V-band and the male brown genal spot, and from A. levefasciata in having shorter terminalia (oviscape length less than 4 mm vs. greater than 8 mm; phallus less than 5 mm vs. greater than 10 mm) and the shape of the aculeus tip (lateral margins slightly convex, not distinctly concave).

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

Head: Yellow to orange except brown ocellar tubercle. 2–3 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, about as long as ocellar tubercle. Facial carina, in profile, straight to slightly concave dorsally and medially. Antenna extended ca. 0.75 distance to ventral facial margin.

Thorax: Mostly yellow to orange, without brown markings, typical white to pale yellow areas poorly differentiated in type specimens. Subscutellum and mediotergite entirely orange. Mesonotum 2.25–3.98 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae yellowish. Chaetotaxy typical for genus. Katepisternal seta weak, at most slightly longer but weaker than postocellar seta, yellowish.

Legs: Entirely yellow to orange.

Wing ( Figs. 14–16 ): Length 5.50–8.25 mm, width 2.05–2.90 mm, ratio 2.52–2.73. Apex of vein R1 at 0.58– 0.65 wing length, distal to crossvein r-m. Pterostigma elongate; cell c 0.89–1.13 times as long as pterostigma; pterostigma 4.4–5.3 times as long as wide. Vein R2+3 strongly sinuous. Crossvein r-m at 0.63–0.69 distance from bm-cu to dm-cu on vein M. Vein M very strongly curved apically; cell r4+5 0.50–0.64 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.54–1.68 times as long as anterior margin. Wing pattern mostly orange, sometimes pale. C-band mostly orange, more opaque in pterostigma. C-band and Sband very narrowly connected or separated along costa by hyaline band that tapers anteriorly in cell r1, reaching or almost 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 in basal part of cell r2+3. Cell dm with basal hyaline area small. Basal half of S-band mostly orange, posterodistal margin often orange brown in cells dm and cu1; distal section orange except orange brown apically in cells r2+3 and r4+5, narrowing along vein R2+3 or in cell r2+3, distal half relatively slender, at apex of vein R2+3 0.42–0.57 times width of cell r2+3, extended to apex of vein M; hyaline area proximal to apex of band extending to vein R2+3. V-band incomplete; proximal arm slender, diffuse, section bordering dm-cu orange brown, fading anteriorly, faint or absent in anterior half or more of cell r4+5, separate from S-band anteriorly, on posterior margin with short, proximal extension at most one-third distance to vein A1+Cu2; distal arm absent.

Abdomen: Mostly orange, without brown markings. Setulae yellow to orange.

Male terminalia: Lateral surstylus moderately long, extended beyond prensisetae by 2.0–2.5 times length of prensiseta; in lateral view (Fig. 43) slender and slightly posteriorly curved; in posterior view (Fig. 44) tapering, then almost parallel-sided subapically, lateral margin slightly concave, apex rounded or slightly truncate, medial margin gradually convex. Proctiger with ventral and lateral sclerotized areas connected. Phallus 4.0– 4.7 mm long, 1.18–1.78 times as long as mesonotum; glans 0.55–0.60 mm long, 0.13–0.14 times as long as phallus.

Female terminalia: Oviscape 2.65–3.30 mm long, 0.93–1.06 times as long as mesonotum, straight in lateral view, entirely yellow to orange; spiracle at basal 0.26–0.33. Eversible membrane ( Fig. 24 ) with 20– 25 strong, hooklike dorsobasal scales in 4 irregular rows in subtriangular to semicircular pattern. Aculeus ( Fig. 34 ) straight in lateral view, 2.85–3.24 mm long, 0.95–1.08 times oviscape length; in ventral view base strongly expanded, 0.19– 0.22 mm wide; shaft 0.10–0.12 mm wide at midlength; tip ( Fig. 35 ) 0.22–0.29 mm long, 0.07–0.10 times aculeus length, 0.10–0.12 mm wide, 1.91–2.70 times as long as wide, triangular, lateral margin slightly convex and gradually tapered to blunt apex, nonserrate, 0.06–0.07 mm wide in lateral view, 0.62–0.74 times ventral width. Spermathecae slightly coiled.

Distribution. Anastrepha raveni is known only from eastern Perú (Huánuco, Junín, Madre de Dios).

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