Body. Setae orange, or dark 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 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 3.8–4.4 mm (3.87–4.36, n=10). 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 moderately developed, larger than postocellar seta, but much smaller and weaker than anepimeral seta, or weak, no larger than postocellar seta, or absent ([recheck]). Mesonotum yellow, or orange. Scutum presutural dorsocentral pale vitta absent; with 2 (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.
Wings. Wing length 8.6–10.6 mm (8.95–10.2, n=8). 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 small or absent, not extending beyond cell r1 nor distally beyond level of basal third of pterostigma (usually), or elongate, extending in cell r1 at least to level of one-third length of pterostigma but not into cell r2+3 (yellow area extended only narrowly into cell r1 to level of 0.20–0.33 of length 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 to vein R4+5 (usually), or extended into cell br but not reaching vein R4+5 (1.00–1.25 times as long as distal brown area of cell). 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 with distinct incision in cell cu1. S-band base with extension in middle of cell cu1 to or almost 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, or 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 not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band; connected to extension of basal part of S-band in cell cu1; connected anteriorly to S-band along vein R4+5 or in cell r2+3 (connected broadly); not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V 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) 0.67–0.9 (0.73–0.83, n=7). Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. Cell c: pterostigma ratio (cell c length/pterostigma length) 1.20–1.41, n=8. Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.50–0.55, n=5. 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) 0.65–0.68, n=8. Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 1.1–1.35 (1.13–1.31, n=8). Cell bcu ratio (length/anterior margin length along vein Cu) 1.55–1.70, n=5. Cell bcu posteroapical lobe shorter than vein A1+Cu2. 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. Abdominal tergites evenly microtrichose. Epandrium posterodorsal margin evenly rounded. Phallus length 6.49–7.00, n=4; ratio (phallus length/mesonotum length) 1.51–1.71, n=4. Glans present; without spinules. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape at least apex brown; straight; length 4–4.9 mm (4.07–4.83, n=4); length ratio (oviscape length/mesonotum length) 1–1.2 (1.05–1.13, n=4); spiracle ratio (distance from base to spiracle/oviscape length) 0.24–0.28, n=4. Eversible membrane with dorsobasal denticles with gap of membranous or no denticles separating apical row(s) from smaller basal denticles. Eversible membrane with 11–16 denticles ((12–15) long slender hooklike dorsobasal denticles in 1–2 irregular rows separated from minute basal denticles by several rows of weakly sclerotized, small, more widely spaced denticles). Aculeus length 3.3–4.45 mm (4.02–4.07, n=2; lower limit for female with shorter oviscape). Aculeus length/oviscape length 0.84, n=2. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length 0.08–0.13 mm (0.09–0.12, n=4); width 0.025–0.05 mm (0.03–0.045, n=4); length/width in ventral view 2.25–2.78, n=4; depth (width in lateral view)/width (in ventral view) 0.87–0.89, n=3; lateral margins not curved dorsally; not flared outward at or proximal to base; distal 0.70–0.78 produced ventrally, oval; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip. Egg egg shape unknown.
