Anastrepha hambletoni Lima

Morphology

Body. Setae orange brown, or red brown ("castanha", Lima 1934; "marrom claras", Zucchi 1978).

Thorax. Mesonotum length 3.1–3.9 mm (3.5, Zucchi 1978). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Mesonotum yellow, or orange. 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.

Wings. Wing length 6.5–8 mm (7.0, Stone 1939; 7.5, Zucchi 1978). 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). Cell c infuscated basally, with distinctly hyaline subapical area extended from costa to vein Sc. 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 (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 not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band; 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. 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) 0.5–0.65 (0.58, measured from Lima 1934, fig. 23). Cell c: pterostigma ratio (cell c length/pterostigma length) 1.2–1.45 (1.33, measured from Lima 1934, fig. 23). Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.53–0.59 (0.56, measured from Lima 1934, fig. 23). Vein R2+3 slightly sinuous, or strongly 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) 0.6–0.66 (0.63, measured from Lima 1934, fig. 23). 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; length 4.5–5.5 mm (5.0, Stone 1939). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern, or all small, weakly developed, in triangular to semicircular pattern (needs to be reexamined in holotype). Aculeus length 4–5 mm (4.5, Zucchi 1978). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip width 0.04–0.06 mm (0.05); lateral margins not curved dorsally; not flared outward at or proximal to base; without ridges or lobes; 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.
