Body. Setae golden to pale orange, or orange, or orange brown.
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 with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face. Arista of male without preapical expansion. Palpus in lateral view evenly setulose.
Thorax. Mesonotum length 2.6–3.25 mm (Stone 1942). 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, or absent. Mesonotum yellow, or orange. Scutum with 2 (sublateral) pale postsutural vittae, or with 3 (both medial and 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. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.
Wings. Wing length 6–7.5 mm (6.25–7.32, Stone 1942, Korytkowski 2001). 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 broad, extending distally into cells r1 and r2+3 at least to level of midlength of pterostigma. C-band and S-band 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 posterior margin without incision in cell cu1, or with weak 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 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, or with very narrow marginal hyaline band in cell r2+3 or with small marginal hyaline spot(s) near apices of veins R2+3 and/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. Apex of V-band not extended from vein R4+5 to vein M, hyaline area present between band and vein M. 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. Cell c: pterostigma ratio (cell c length/pterostigma length) 1.1, Korytkowski 2001. Pterostigma ratio 3.4–4 (Korytkowski 2001). 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) 0.69–0.74 (0.72, n=1, Korytkowski 2001). Costa in male with setulae on anterior margin between crossvein h and apex of vein R1 similar to other setulae. 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. Epandrium in lateral view shorter than high. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view long, inner side convex, outer side concave. Phallus length 2–2.4 mm (2.22, n=1, Korytkowski 2001); ratio (phallus length/mesonotum length) 0.65–0.9 (0.77, n=1, Korytkowski 2001). Glans present; without spinules. Oviscape entirely yellow to orange brown; straight; length 1.55–1.8 mm (Stone 1942, Korytkowski 2001); length ratio (oviscape length/mesonotum length) 0.5–0.6 (0.55, n=1, Korytkowski 2001); spiracle ratio (distance from base to spiracle/oviscape length) 0.4–0.45 (0.43, n=1, Korytkowski 2001). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 10–15 denticles (relatively short hooklike denticles in suboval pattern). Aculeus length 1.25–1.55 mm (1.29–1.50, Stone 1942, Korytkowski 2001). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length 0.14–0.22 mm (Martinez 2007); lateral margins curved dorsally (strongly); not flared outward at or proximal to base, or flared outward at or proximal to base, lateral margin strongly concave; without ridges or lobes; without elongate dorsolateral depressions apically; with fine serrations, or with medium sized serrations; serrated part 1–1.25 times length of tip (1.13, n=1, Korytkowski 2001). Aculeus tip with serrations separated by less than width of serration. Egg without lobe (Figueiredo et al. 2011).
