Body. Setae golden to pale orange, or orange.
Thorax. 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, or moderately developed, larger than postocellar seta, but much smaller and weaker than anepimeral seta. Scutum posteriorly with pair of brown spots or markings. Scutum posteriorly with only pair of ovoid brown spots on or slightly lateral to dorsocentral line; without brown vittae (presumed). Scutellum entirely yellow or with dark markings only on extreme base of disk (presumed). Mesopleuron mostly yellow to orange, without brown markings (presumed). Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange.
Wings. Wing length 7–8.5 mm (7.75, Stone 1939). 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 (narrowly); 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 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 posterior margin without incision in cell cu1. 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; 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, or incomplete, not reaching vein R4+5, but extended from vein M to wing margin (extended almost to R4+5); isolated, not connected to proximal arm of V-band or to S-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) 0.5–0.75 (0.625, measured from Lima 1934, fig. 18). Cell c: pterostigma ratio (cell c length/pterostigma length) 1.22, measured from Lima 1934, fig. 18. Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.53–0.57 (0.55, measured from Lima 1934, fig. 18). Vein R2+3 not sinuous; without accessory vein. Vein R4+5 distal to crossvein r-m strongly bowed slightly distal to level of anterior end of crossvein dm-cu. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.58–0.64 (0.61, measured from Lima 1934, fig. 18). 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. Oviscape length 2.8–3.2 mm (3.0, Lima 1934). Aculeus tip width 0.02–0.03 mm (0.025); not flared outward at or proximal to base; not serrate; serrated part 0 times length of tip.
Miscellaneous. Data source: Lima 1934, Stone 1939. Data recording inadequate. Sex of recorded specimens: male and female. Species group: punctata 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.
Illustrations. • Abdomen, female (ventral) (Lima 1934, est. LXXVI, fig. 67). • Terminalia, male & female (Lima 1934).
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.
