Anastrepha nascimentoi Zucchi

Morphology

Thorax. Mesonotum length 2.6–3.4 mm (3.0, n=1, Zucchi 1979). Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange.

Wings. Wing length 7.5–9.5 mm (8.0–9.0, n=2, Zucchi 1979). 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 connected (narrowly along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended to vein R4+5. Cell r1 basomarginal hyaline spot triangular to quadrate. Cell r1 basomarginal hyaline spot apex aligned proximal to crossvein r-m. 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. 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; 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. 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; 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 2–2.5 mm (n=2, Zucchi 1979); ratio (oviscape length/mesonotum length) 0.65–0.85 (0.67–0.83, n=2, Zucchi 1979). Aculeus length 1.6–1.9 mm (1.75, n=2, Zucchi 1979). Aculeus tip flared outward at or proximal to base, lateral margin strongly concave; with fine serrations; serrated part 1–1.2 times length of tip (Zucchi 1979, estimated from fig. 6). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
