Body. Setae dark red brown, or dark brown to black.
Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 4–5. 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; without brown markings. Antenna not extended to ventral margin of face.
Thorax. Mesonotum length 3.9–4.7 mm (3.95–4.60). Scutum mostly or entirely microtrichose. 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 weak, no larger than postocellar seta. Mesonotum orange, or dark orange. Scutum presutural dorsocentral pale vitta absent; with 3 (both medial and sublateral) pale postsutural vittae. 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. Mediotergite entirely yellow to orange.
Wings. Wing length 8.8–11 mm (9.1–10.6). 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). Cell c mostly or entirely infuscated to subhyaline, or paler posteriorly, without distinct subapical hyaline area. 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 small or absent, not extending beyond cell r1 nor distally beyond level of basal third of pterostigma. C-band and S-band connected (broadly along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended into cell br but not reaching vein R4+5. Cell r1 basomarginal hyaline spot triangular to quadrate. Cell r1 basomarginal hyaline spot apex aligned proximal to crossvein r-m, or apex aligned with 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 with weak incision in cell cu1, or with distinct incision in cell cu1. 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 entirely brown. Subapical hyaline area in radial cells distal to r-m extending anteriorly to vein R2+3, or extending into cell r2+3 but not reaching 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 extended to apex of vein M (narrowly touching), or 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; connected anteriorly to S-band along vein R4+5 or in cell r2+3 (sometimes very broadly); not connected to S-band in cell dm, or connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band, or connected to proximal arm of V-band and broadly connected with apical part of S-band. S-band distal section width ratio (width of S-band/width of cell r2+3, both measured perpendicular to costal margin at apex of vein R2+3) 0.65–0.85 (0.67–0.83). Cell c: pterostigma ratio (cell c length/pterostigma length) 1.05–1.25 (1.10–1.19). Vein R2+3 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) 0.65–0.72 (0.66–0.70). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.8–1 (0.83–0.96). Cell bcu ratio (length/anterior margin length along vein Cu) 1.45–1.6 (1.48–1.54). Crossvein dm-cu orientation with anterior end more distal than posterior end.
Abdomen. Abdomen ovate or parallel-sided, syntergite 1+2 gradually broadening or parallel-sided. Abdominal tergite without brown markings. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in lateral view flattened, slightly curved, apex acute. Phallus length 6–7.5 mm (n=4); ratio (phallus length/mesonotum length) 1.5–1.85 (1.52–1.81, n=4). Glans present; without spinules. Oviscape straight; length 4.9–5.9 mm; length ratio (oviscape length/mesonotum length) 1.2–1.35 (1.21–1.33); spiracle ratio (distance from base to spiracle/oviscape length) 0.2–0.3 (0.23–0.27). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 25–45 denticles (large hooklike denticles in triangular pattern). Aculeus length 5–6 mm (5.1–5.9). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.26–0.3 mm; width 0.1–0.11 mm; not flared outward at or proximal to base; without ridges or lobes; with medium sized serrations; serrated part 0.65–0.8 times length of tip (0.69–0.76). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration. Spermathecae sclerotized.
