Anastrepha carreroi Canal

Morphology

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

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–4. 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. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 2.5–3.2 mm (2.61–3.07, Canal 2010). 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 presutural dorsocentral pale vitta absent; with 2 (sublateral) pale postsutural vittae; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings (??confirm, check for state 2). 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, or yellow to red brown medially, dark brown laterally. Mediotergite entirely yellow to orange, or yellow to red brown medially, dark brown laterally. Femora entirely yellow to orange.

Wings. Wing length 6–9.1 mm (6.04–9.07, Canal 2010). 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 (narrowly by hyaline band from cell bm to costal margin in cell r1, narrowed along vein R4+5), or 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 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. 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 M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.68–0.71 (Canal 2010). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.9–1.25 (1.00–1.16, Canal 2010). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Epandrium in lateral view shorter than high. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in lateral view flattened, slightly curved, apex acute. Phallus length 3.2–3.8 mm (Canal 2010). Glans present; without spinules. Oviscape straight; length 2.6–3.33 mm (2.66–3.25, Canal 2010); length ratio (oviscape length/mesonotum length) 0.85–1.2 (0.89–1.16, Canal 2010); spiracle ratio (distance from base to spiracle/oviscape length) 0.27–0.33 (Canal 2010). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 30–40 denticles (with approximately 35 strong, slender hook-like dorsobasal denticles in semi-elliptic pattern). Aculeus length 2.4–3.1 mm (2.48–2.62, Canal 2010). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.25–0.35 mm (0.27–0.34, Canal 2010); width 0.12–0.15 mm (0.127–0.145, Canal 2010); length/width in ventral view 1.1–1.75 (1.20–1.61, Canal 2010); 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, or with medium sized serrations; serrated part 0.67–0.8 times length of tip (Canal 2010). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
