Body. Setae orange, or dark red brown, or dark brown to black.
Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Orbital setae 2. 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 2.5–3.4 mm (2.9, n=2, Stone 1942). 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 sublateral postsutural vitta extended posteriorly to intra-alar seta. 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. Mediotergite yellow to red brown medially, dark brown laterally.
Wings. Wing length 6–7 mm (6.5, n=2, Stone 1942). 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. 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 base without extension in middle of cell cu1 to posterior wing margin; without extension in cell a1 to or almost to posterior 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. 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; not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band. Vein R2+3 not sinuous; without accessory vein. Crossvein dm-cu orientation with anterior end more distal than posterior end.
Abdomen. Abdominal tergite without brown markings. Oviscape straight; length 1.75–2.25 mm (1.8–2.1, Stone 1942, Canal 2010). Aculeus length 1.45–1.8 mm (1.50–1.75, Stone 1942; 1.5, Canal 2010). Aculeus tip length 0.16–0.2 mm (0.17, n=1; 0.18, Canal 2010); width 0.09–0.11 mm (0.10 in Colombian female, Canal 2010); not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with large serrations; serrated part 0.7–0.95 times length of tip (0.79, n=1; 0.89, Canal 2010). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
Miscellaneous. Data source: Stone 1942. Sex of recorded specimens: female. Species group: fraterculus group.
Biology and economic significance. This species is a potential pest of species of Spondias, its only recorded host. Refer to the 'Tephritidae Databases' in the USDA Compendium of Fruit Fly Host Information (https://coffhi.cphst.org/) for host plant information.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
