Anastrepha elongata Fernandez

Morphology

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

Head. Facial carina in profile concave or flat on dorsal 2/3. Face with ventral part gradually tapered laterally.

Thorax. Mesonotum length 3.75–5.25 mm (4.00–4.98, Caraballo 1981). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Mesonotum yellow, or orange. Scutum with 3 (both medial and sublateral) pale postsutural 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.

Wings. Wing length 9.75–12 mm (9.90–11.78, Caraballo 1981). 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 broad, extending distally into cells r1 and r2+3 at least to level of midlength of pterostigma. C-band and S-band separated (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 posterior margin without incision in cell cu1, or with weak incision in cell cu1. 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 extended to apex of vein M, or not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band; 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; connected to proximal arm of V band. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. 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. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Oviscape length 9.5–12.75 mm (9.79–12.45, Caraballo 1981). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus length 9.25–12.5 mm (9.58–12.28, Caraballo 1981). Aculeus tip length 0.43–0.58 mm (0.45–0.56, Caraballo 1981); not flared outward at or proximal to base; without ridges or lobes; with minute serration, visible only with compound microscope, or with fine serrations; serrated part 0.25–0.4 times length of tip (0.33, Caraballo 1981). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
