Anastrepha velezi Norrbom

Morphology

Body. Setae dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–4. Orbital setae 1, or 2 (rarely). Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 2.75–3.54 mm. Scutum nonmicrotrichose (except postsurural lateral margin lateral to level of intra-alar seta). 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 with 2 (sublateral) pale postsutural vittae; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. 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 7.65–8.48 mm. 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, narrowed along vein R4+5), or connected (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 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. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. Area between S-band and V-band entirely microtrichose in cells dm and 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.

Abdomen. Abdominal tergite without brown markings. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view without basolateral lobe. Phallus length 6.9–7.1 mm; ratio (phallus length/mesonotum length) 2.23–2.37. Glans present; without spinules. Oviscape straight; length 5.45–6.48 mm; length ratio (oviscape length/mesonotum length) 1.68–2.05; spiracle ratio to mesonotum length (distance from base to spiracle/mesonotum length) 0.2–0.22. Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus length 4.82–5.48 mm. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.37–0.45 mm; width 0.12–0.13 mm; gradually tapering, blade-like, with flattened cross-section; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip. Spermathecae sclerotized; ovoid.
