Anastrepha barnesi Aldrich

Morphology

Body. Setae dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. 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 without brown markings.

Thorax. Mesonotum length 3.8–4.6 mm. 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 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.

Wings. Wing length 9–11 mm (9.26–10.50). 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. 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 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 extending anteriorly to vein R2+3. 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. 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. Abdominal tergite without brown markings. Lateral surstylus in posterior view short, somewhat boot-shaped, truncate and with apex slightly laterally projected. Surstylus in posterior view with lateral margin concave. Surstylus in posterior view with mesal margin convex. Glans present; without spinules. Oviscape length 9–12 mm (10.6, n=1); spiracle ratio (distance from base to spiracle/oviscape length) 0.12–0.18 (0.15, n=1). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus length 9–11 mm (10.0, n=1). Aculeus tip lateral margins not curved dorsally; 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. Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.

Miscellaneous
