Anastrepha doryphoros Stone

Morphology

Body. Setae dark red brown, or dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–4. Orbital setae 2. Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 3.25–5.35 mm (3.55–5.05, n=3). Postpronotal lobe and notopleuron entirely microtrichose. Scutum microtrichose except paired elongate bare areas (with nonmicrotrichose vitta between acrostichal and dorsocentral lines, extended posteriorly to level of dorsocentral seta, also with large triangular or ovoid lateral presutural nonmicrotrichose area and sometimes with small nonmicrotrichose vitta between dorsocentral and intra-alar setae on posterior third). Scutellum disc mostly or entirely without microtrichia. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length; postpronotal seta on posterior half of postpronotal lobe. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Katepisternal seta weak, no larger than postocellar seta. Mesonotum orange, or dark orange. Scutum presutural dorsocentral pale vitta absent; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta narrow posteriorly, not expanded (not extended laterally to acrostichal seta); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings. Scutum without brown vittae. Scutellum entirely yellow or with dark markings only on extreme base of disk. Mesopleuron mostly yellow to orange, without brown markings. Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wings. Wing length 9.5–13.5 mm (9.81–13.23, n=3). Wing pattern without typical bands. Cell c mostly or entirely infuscated to subhyaline, or paler posteriorly, without distinct subapical hyaline area. C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3; yellow or orange area posterior to pterostigma filling all of band in cells r1 and r2+3. C-band and S-band connected (broadly along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band not extended into cell br. Cell r1 basomarginal hyaline spot semicircular to subovoid. Cell r1 basomarginal hyaline spot apex aligned distal to crossvein r-m. S-band extended anteriorly to vein R4+5 and covering all of crossvein r-m. Cell bm entirely hyaline or infuscated only along subapical fold. S-band base without extension in middle of cell cu1 to posterior wing margin; without extension in cell a1 to or almost to posterior margin. Subapical hyaline area in radial cells distal to r-m S-band entirely covering cell r2+3 distal to r-m (absent). S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. V-band proximal arm as dark as apical half of S-band; not connected anteriorly to S-band, or connected anteriorly to S-band along vein R4+5 or in cell r2+3; connected to S-band in cell dm. V-band distal arm complete, or absent (completely fused to apical part of S-band); connected to proximal arm of V-band and broadly connected with apical part of S-band (entirely fused with S-band). Apex of V-band extended from vein R4+5 to vein M, no hyaline area present between band and vein M. S-band distal section width ratio (width of S-band/width of cell r2+3, both measured perpendicular to costal margin at apex of vein R2+3) 1. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. Area between S-band and V-band entirely microtrichose in cells dm and cu1. Cell c: pterostigma ratio (cell c length/pterostigma length) 1.06–1.13, n=3. Pterostigma ratio 4.50–4.86, n=3. Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.57, n=3. Vein R2+3 not sinuous; without accessory vein. Vein R4+5 distal to crossvein r-m more or less evenly curved or not strongly bowed medially. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.6–0.65 (0.61–0.64, n=3). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.85–1.05 (0.91–1.02, n=3). Cell bcu ratio (length/anterior margin length along vein Cu) 1.38–1.42, n=3. Cell bcu posteroapical lobe shorter than vein A1+Cu2. Costa in male with setulae on anterior margin between crossvein h and apex of vein R1 similar to other setulae. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdomen ovate or parallel-sided, syntergite 1+2 gradually broadening or parallel-sided. Abdominal tergite without brown markings. Oviscape straight, or strongly dorsally arched; length 8–18 mm (8.6–17.57, n=2); length ratio (oviscape length/mesonotum length) 2.2–3.6 (2.42–3.48, n=2); spiracle ratio (distance from base to spiracle/oviscape length) 0.15–0.22 (0.16, n=1). Eversible membrane with dorsobasal denticles all sclerotized, relatively small, in very elongate pattern. Aculeus length 7–17 mm (7.5, n=1). Aculeus length/oviscape length 0.83–0.93 (0.87, n=1). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length/aculeus length 0.02–0.05 (0.04, n=1). Aculeus tip length 0.3–0.4 mm (0.33, n=1); width 0.1–0.13 mm (0.11, n=1); length/width in ventral view 3.0, n=1; lateral margins not curved dorsally; tapered basally, then parallel-sided, then gradually tapered (margin sharply narrowed at apical 2/5, then gradually tapered); not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip.
