Anastrepha sinuosa Canal

Morphology

Body. Setae red brown, or dark red brown, or dark brown to black (dark brown in holotype).

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–5 (4 in holotype). 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 2–2.8 mm (2.40, n=1). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Mesonotum yellow, or orange. Scutum presutural dorsocentral pale vitta absent; according to description, all scutal vittae absent, but probably not visible due to condition of holotype. 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.

Wings. Wing length 7.25–8.75 mm (8.07, n=1). Wing pattern typical Anastrepha pattern (S-band complete or at most interrupted at crossvein r-m, C-band and at least proximal arm of V-band present). 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, or broad, extending distally into cells r1 and r2+3 at least to level of midlength of pterostigma. C-band and S-band separated (broadly by hyaline band extended from cell bm to costa distal to apex of vein R1, hyaline band not narrowed along veins R2+3 and R4+5, at most slightly narrowed anteriorly in cell r1). 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. S-band middle section predominantly or entirely orange, often with brown margins. Subapical hyaline area in radial cells distal to r-m extending anteriorly to vein R2+3. S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. S-band distally not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band (faint or interrupted in cell r4+5); extending more than 1/3 distance from apex of vein Cu1 to apex of vein A1+Cu2; not connected anteriorly to S-band; not connected to S-band in cell dm. V-band distal arm complete; isolated, not connected to proximal arm of V-band or to S-band, or connected to proximal arm of V band. Apex of V-band not extended from vein R4+5 to vein M, hyaline area present between band and vein M. Vein R2+3 not sinuous, or slightly 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) 0.66–0.7 (0.68, n=1). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.6–0.9 (0.76, n=1). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Oviscape straight; length 5–6.4 mm (5.69, n=1); length ratio (oviscape length/mesonotum length) 2.15–2.55 (2.37, n=1); spiracle ratio (distance from base to spiracle/oviscape length) 0.2–0.26 (0.23, n=1). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 20–30 denticles (long hook-like denticles in 3 rows). Aculeus length 5–6.4 mm (5.69, n=1). Aculeus length/oviscape length 0.95–1.05 (1.0, n=1). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.3–0.38 mm (0.34, n=1); width 0.05–0.08 mm (0.063?, description says depth, but seems to be describing width); 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.
