Body. Setae orange, or orange brown, or red brown.
Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–5. Orbital setae 2. Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile strongly produced near midheight (especially in female, usually with 1–3 small grooves, in female dorsal margin of produced part often nearly perpendicular to dorsal part of carina). 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 3.3–4.8 mm (3.35–4.74, n=18). Scutum with broad nonmicrotrichose vittae; recheck vs. states. 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, or dark orange. Scutum 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, or with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum posteriorly with dark band or broad marking on posterior margin (band dark orange to moderate brown); 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 7.25–11 mm (7.31–10.90, n=18). 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). 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. 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. Vein R2+3 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. Epandrium posterodorsal margin evenly rounded. Epandrium in lateral view longer than high (confirm). Lateral surstylus in posterior view without basolateral lobe. Phallus length 13.3–15.2 mm (13.6–14.9, n=8); ratio (phallus length/mesonotum length) 3.3–4.4 (3.37–4.30, n=8). Glans present; without spinules. Oviscape length 9.25–12.75 mm (9.37–12.57, n=10); ratio (oviscape length/mesonotum length) 2.2–2.7 (2.25–2.65, n=9); spiracle ratio (distance from base to spiracle/oviscape length) 0.17–0.2 (0.18–0.19, n=5); spiracle ratio to mesonotum length (distance from base to spiracle/mesonotum length) 0.40–0.49, n=5. Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 30–45 denticles (large hooklike denticles in triangular pattern). Aculeus length 8.8–12.5 mm (8.97–12.26, n=4). Aculeus length/oviscape length 0.91–0.98, n=4. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length/aculeus length 0.02–0.04 (0.03, n=4). Aculeus tip length 0.26–0.34 mm (0.28–0.32, n=4); width 0.14–0.18 mm (0.145–0.180, n=3); length/width in ventral view 1.71–1.93, n=3; lateral margins not curved dorsally; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with medium sized serrations; serrated part 0.59–0.66 times length of tip. Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration. Spermathecae sclerotized; spherical, or ovoid.
