Diagnosis. Anastrepha fenestrella differs from most species of Anastrepha in having an extension from the basal part of the S-band to the posterior wing margin in the middle of cell cu 1 that is not connected to the posterior end of the proximal arm of the V-band. It differs from the other species having that wing character, except A. fenestrata , in having an orange area in cell r 1 posterior to the pterostigma and another bordering crossvein r-m and extending into cell dm, and in having the apex of vein M strongly curved, the width of cell r at apex less than 0.80 its width at dm-cu. It differs from A. fenestrata in having shorter terminalia (oviscape 1.65–1.90 mm long, 0.37–0.42 times as long as mesonotum vs. 2.49 mm long, 0.59 times mesonotum length; aculeus 0.84–0.92 mm long vs. 1.76 mm) and the aculeus tip distinctly longer than wide (ratio 1.43–1.72), sagittate, and distinctly expanded basally.

Description. Mostly yellow to orange, with white to pale yellow markings. Setae dark brown to black.

Head: Yellow to orange except brown ocellar tubercle. 3–5 (usually 4–5) frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 2 times as long as ocellar tubercle. Facial carina, in profile, slightly concave to slightly convex (usually straight) dorsally and medially. Antenna extended 0.60–0.85 distance to ventral facial margin.

Thorax ( Fig. 14 ): Mostly yellow to orange with following areas white or pale yellow (not always well differentiated in dried specimens): postpronotal lobe; diffuse medial vitta, inverted T-shaped or reduced to quadrate posterior area extended laterally to dorsocentral seta; paired sublateral scutal vitta from transverse suture to posterior margin, including intra-alar seta; entire scutellum; dorsal margin of anepisternum; dorsal margin of katepisternum; katepimeron; and most of anatergite and katatergite. Posterior margin of scutum with broad brown band with more or less straight anterior margin, sometimes extended to but not completely including acrostichal seta, and ending laterally at sublateral white vitta, not extended to intra-alar seta. Subscutellum and mediotergite entirely orange. Mesonotum 3.9–4.43 mm long. Scutum entirely microtrichose; setulae mostly yellow to orange, brownish laterally. Katepisternal seta weak, yellow, less than 0.33 as large as anepimeral seta.

Wing ( Figs. 34–35 ): Length 8.75–10.10 mm, width 3.55–4.07 mm, ratio 2.46–2.65. Apex of vein R 1 at 0.54–0.55 wing length. Cell c 1.03–1.30 times as long as pterostigma; pterostigma 3.11–4.69 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.65–0.67 distance from bm-cu to dm-cu on vein M. Vein M very strongly curved apically; cell r 0.56–0.81 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.56–1.68 times as long as anterior margin. Wing pattern mostly moderate to dark brown and orange. C-band with cell bc yellowish to subhyaline; cell c yellowish basally and posterodistally, anterior margin narrowly yellowish, brown on distal 0.25–0.50, posteriorly with broad elongate medial hyaline to subhyaline nonmicrotrichose area; yellow area extended into posterobasal corner of pterostigma and broadly into cell r 1, broadly reaching R 2+3, and extending distally to 0.33–0.50 length of pterostigma; remainder of band in pterostigma, r 1, r 2+3, and br dark brown. C-band and S-band broadly connected along vein R 4+5, hyaline area in cell br small, usually reaching vein R 4+5 but shorter than distal brown area of cell; cell dm with basal hyaline area moderately large. Basal half of S-band mostly dark brown, with large medial orange area broadly bordering crossvein r-m and extending broadly into anterior 0.50–0.67 of cell dm, occasionally (usually narrowly) reaching proximal margin of band in dm; with brown, lobelike projection to posterior wing margin in middle of cell cu 1 but not connected to proximal arm of V-band along wing margin; section between vein M and costa often and distal section of band always also with orange areas with broad brown margins, distal section relatively broad, at apex of vein R 2+3 0.76–0.82 times width of cell r 2+3, usually broadening in cell r 2+3, extended to apex of vein M; hyaline area proximal to it usually ending at vein R 2+3 (very narrowly separated from vein in Costa Rican male). Hyaline basomarginal spot in cell r 1 triangular, sometimes with blunt apex, usually extended to R 4+5 (except in Costa Rican male), its apex aligned slightly proximal to crossvein r-m. V-band complete, mostly brown, broadly connected to Sband in cell r 2+3; proximal arm with slender medial orange area bordering anterior 0.80 or more of dm-cu, narrowing posteriorly, and extending anteriorly at least midway across cell r 4+5 or often beyond vein R 4+5; proximal arm moderately broad anteriorly, gradually broadening posteriorly, without basal extension along wing margin, at level of vein M 1.8–2.3 times as wide as distal arm and 1.2–1.6 times as wide as hyaline area proximal to it in cells r 4+5 and dm; distal arm relatively broad, connected to proximal arm.

Abdomen: Mostly orange, without brown markings.

Male terminalia ( Fig. 198 ): Lateral surstylus short, extended beyond prensisetae by ca. 2 times length of prensiseta; in lateral view posteriorly curved; in posterior view similar to A. pittieri , gradually tapered to bluntly acute apex, lateral margin slightly concave to slightly convex, medial margin convex. Proctiger with ventral and lateral sclerotized areas connected but lateral areas separate dorsally. Phallus 2.17–2.30 mm long, 0.52–0.58 times as long as mesonotum; glans 0.45 mm long.

Female terminalia: Oviscape 1.65–1.90 mm long, 0.37–0.42 times as long as mesonotum; usually dark orange to brown dorsally, yellow to paler orange ventrally; spiracle at basal 0.42–0.45. Eversible membrane ( Fig. 72 ) with 8–12 moderately long hooklike dorsobasal scales in 1 irregular row distal to similar number of small, stout scales. Aculeus ( Fig. 115 ) slightly ventrally curved in lateral view, 0.84–0.92 mm long; in ventral view base expanded, 0.18–0.24 mm wide; shaft 0.07–0.09 mm wide at midlength; tip ( Figs. 148 , 172 ) 0.14–0.15 mm long, 0.09–0.105 mm wide, 1.43–1.72 times as long as wide, 0.04–0.06 mm wide in lateral view, 0.44–0.60 times ventral width, in ventral view triangular with margins straight and with medium sized serrations to or slightly beyond base, serrate part 0.93–1.13 times as long as tip, at base of serrate part distinctly flared and wider than at shaft. Spermathecae ( Fig. 104 ) spherical.
