Body. Setae dark brown to black.
Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. 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 without brown markings. Antenna not extended to ventral margin of face.
Thorax. Mesonotum length 3.5–4.1 mm (3.81, n=1). Scutum mostly or entirely microtrichose (lectotype is debris covered, but appears 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 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. Mesopleuron mostly yellow to orange, without brown markings. Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange.
Wings. Wing length 8–9 mm (8.45, n=1). 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 separated (by hyaline band from cell bm to costal margin). 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. 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; 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. Vein R2+3 not sinuous; without accessory vein.
Abdomen. Abdominal tergite without brown markings. Oviscape straight; length 4–4.5 mm (4.25, n=1); length ratio (oviscape length/mesonotum length) 1–1.25 (1.12, n=1); spiracle ratio (distance from base to spiracle/oviscape length) 0.22–0.3 (0.26, n=1); spiracle ratio to mesonotum length (distance from base to spiracle/mesonotum length) 0.27–0.35 (0.31, n=1). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern ("rasper of rather long, curved hooks" (Stone 1942a)). Aculeus length 3.75–4.25 mm (4.01, n=1). Aculeus length/oviscape length 0.94, n=1. Aculeus tip length 0.23–0.31 mm (0.27, n=1); width 0.05–0.08 mm (0.065, n=1); length/width in ventral view 3.5–5 (4.23, n=1); lateral margins not curved dorsally; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip.
Miscellaneous. Data source: Stone 1942. Sex of recorded specimens: female. Species group: mucronota group.
Biology and economic significance. This species is not considered economically important. 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.
