Anastrepha castilloi Norrbom

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 4–6. Orbital setae 2. Ocellar seta weak, small or absent. Gena without brown spot. Face with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 3.33–4.2 mm. Postpronotal lobe and notopleuron entirely microtrichose. Scutum mostly or entirely microtrichose. Scutellum disc entirely microtrichose. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length; postpronotal seta on posterior half of postpronotal lobe. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Katepisternal seta weak, no larger than postocellar seta. Mesonotum dark orange, or orange brown, or dark brown; without pale spot or vitta on presutural lateral margin of scutum or posterior part of notopleuron, or with short presutural lateral pale vitta on lateral margin of scutum, not extended onto notopleuron. Scutum presutural dorsocentral pale vitta present and connected anteriorly with pale area of postpronotal lobe, or absent (usually present, slender, sometimes poorly differentiated in dried specimens); with 3 (both medial and sublateral) pale postsutural vittae, or with 5 (medial, dorsocentral, and sublateral) pale postsutural vittae; pale medial vitta with posterior end ovoid, or with posterior end triangular (extended laterally to or almost to dorsocentral seta); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings, or with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum posteriorly with irregular brown markings; scutal posterior brown band not extended laterally to include intra-alar seta; without brown vittae. Scutellum entirely yellow or with dark markings only on extreme base of disk, or with base of disk brown, extending to or beyond level of basal seta. Subscutellum yellow to red brown medially, dark brown laterally. Mediotergite yellow to red brown medially, dark brown laterally.

Wings. Wing length 7.65–9.22 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 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 broadly connected along costal margin (connection extending to vein R4+5). Basal hyaline area between C-band and S-band extended to vein R4+5. 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 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 (ending at vein M); not connected to S-band in cell dm. V-band distal arm absent. 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. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.65–0.71 (0.66–0.70). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Epandrium posterodorsal margin evenly rounded. Phallus length 5.47–5.95 mm; ratio (phallus length/mesonotum length) 1.33–1.54. Glans present; without spinules. Oviscape straight; length 4.49–4.95 mm; length ratio (oviscape length/mesonotum length) 1.21–1.35. Eversible membrane with dorsobasal denticles with gap of membranous or no denticles separating apical row(s) from smaller basal denticles. Aculeus length 3.95–4.53 mm. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.38–0.45 mm (0.4–0.43); width 0.05–0.06 mm; 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.
