Head. Orbital setae 2. Ocellar seta weak, small or absent. 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 2.2–3.2 mm (2.33–3.08, n=7). 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. Mesonotum yellow, or orange. Scutum with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta narrow posteriorly, not expanded, or with posterior end ovoid; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings, or with only single medial brown spot on scuto-scutellar suture (usually). 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 yellow to red brown medially, dark brown laterally. Mediotergite yellow to red brown medially, dark brown laterally. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.
Wings. 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 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 bm entirely hyaline or infuscated only along subapical fold. S-band base without extension in middle of cell cu1 to posterior wing margin. 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. V-band distal arm complete; connected to proximal arm of V band (usually), or isolated, not connected to proximal arm of V-band or to S-band. Pterostigma ratio 2.6–3.3. Ratio of costa length between apices of Sc and R1/length between apices of R1 and R2+3 0.39–0.46. 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. Cell bcu posteroapical lobe shorter than vein A1+Cu2. 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. Lateral surstylus in posterior view long, slightly tapered, somewhat truncate apically. Lateral surstylus in posterior view not boot-shaped. Phallus length 2.2–2.6 mm (2.3–2.5, n=2); ratio (phallus length/mesonotum length) 0.85–1.1 (0.94–1.02, n=2). Glans present; without spinules. Oviscape straight; length 1.55–1.85 mm (1.58–1.83, n=7); length ratio (oviscape length/mesonotum length) 0.5–0.75 (0.58–0.68, n=7). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus length 1.33–1.7 mm (1.39–1.62, n=7; 1.34–1.68, Araujo & Zucchi 2006; 1.35–1.47 in Colombian females, Canal 2010). Aculeus length/oviscape length 0.8–0.92 (0.81–0.91, n=7). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length/aculeus length 0.1–0.14 (0.11–0.13, n=7). Aculeus tip length 0.15–0.22 mm (0.16–0.20, n=7; 0.15–0.22, Araujo & Zucchi 2006; 0.18–0.21 in Colombian females, Canal 2010); width 0.12–0.13 mm (n=7); lateral margins not curved dorsally; gradually tapering, but with medial constriction; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with medium sized serrations; serrated part 0.45–0.7 times length of tip (0.5–0.67, n=7). 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. Egg without lobe.
Sex of recorded specimens: male and female. Species group: fraterculus group.
This species is a pest of a variety of cultivated fruits, especially species of Myrtaceae. The main damage is caused by the larvae, which feed inside the fruit. Refer to the Fruit Fly Databases for host plant information.
