Anastrepha soroana Fernández & Rodríguez


Body. Setae dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 2–4 (3, n=1, Fernandez et al. 1998). Orbital setae 2. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face without brown markings.

Thorax. Mesonotum length 2.65–3.25 mm (2.95, n=1, Fernandez et al. 1998). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Mesonotum yellow, or orange, or dark orange. Scutum pale thoracic markings poorly differentiated in 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 5.4–6.2 mm (5.82, n=1, Fernandez et al. 1998). 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 (narrowly); yellow or orange area posterior to pterostigma broad, extending distally into cells r1 and r2+3 at least to level of midlength of pterostigma. C-band and S-band separated (broadly along veins R2+3 and R4+5 by hyaline band from cell bm to costal margin 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 (yellow in cell r4+5); not connected anteriorly to S-band; not connected to S-band in cell dm. V-band distal arm complete (yellow in cell r4+5); connected to proximal arm of V band. Vein R2+3 not sinuous, or slightly sinuous; without accessory vein. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Oviscape length 2.25–2.75 mm (2.52, n=1, Fernandez et al. 1998); ratio (oviscape length/mesonotum length) 0.75–0.95 (0.85, n=1, Fernandez et al. 1998). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 12–18 denticles ((about 15 in holotype) medium sized denticles in about 5 rows, Fernandez et al. 1998). Aculeus length 2–2.5 mm (2.23, n=1, Fernandez et al. 1998). Aculeus length/oviscape length 0.85–0.93 (0.88, n=1, Fernandez et al. 1998). Aculeus tip length/aculeus length 0.07–0.1 (0.085, n=1, Fernandez et al. 1998). Aculeus tip length 0.16–0.22 mm (0.19, n=1, Fernandez et al. 1998); width 0.05–0.07 mm (0.06, n=1, Fernandez et al. 1998); length/width in ventral view 2.5–3.8 (3.17, n=1, Fernandez et al. 1998); lateral margins not curved dorsally; parallel-sided, then triangular; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with minute serration, visible only with compound microscope, or with fine serrations; serrated part 0.2–0.33 times length of tip (0.26, n=1, Fernandez et al. 1998, fig. 1B). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
