Anastrepha asetaocelata Tigrero & Salas

Morphology

Body. Setae red brown, or dark red brown, or dark brown to black (de color café).

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3. 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 with ventral part gradually tapered laterally. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 3–3.9 mm (3.44, n=1). 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. Katepisternal seta well developed, at least half as large as anepimeral seta. Mesonotum yellow, or orange. Scutum with 2 (sublateral) pale postsutural vittae. Scutum posteriorly without brown or orange brown markings, or with only single medial brown spot on scuto-scutellar suture (spot present in holotype; also scored as without marks because spot often variable in other species). 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 7–9 mm (7.92, n=1). 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), or connected (narrowly along vein R4+5[narrowly connected in holotype but probably variable in species]). 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; 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. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein 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. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Oviscape length 3.7–4.4 mm (4.04, n=1); ratio (oviscape length/mesonotum length) 1–1.35 (1.17, n=1). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with with 9 rows of strong "puntiagudos" denticles. Aculeus length 3.5–4.2 mm (3.83, n=1). Aculeus length/oviscape length 0.9–1 (0.95, n=1). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.3–0.4 mm (0.35, n=1); width 0.13–0.15 mm (0.138, n=1); parallel-sided, then triangular; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with medium sized serrations; serrated part 0.6–0.8 times length of tip (0.69, n=1). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
