Body. Setae dark red brown, or dark brown to black.
Head. Facial carina in profile concave or flat on dorsal 2/3.
Thorax. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Mesonotum yellow, or orange. Scutum pale thoracic marking poorly differentiated in holotype; 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 6.5–8.3 mm (7.4, Blanchard 1961). 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 separated (by hyaline band from cell bm to costal margin; presumed variation), or connected (narrowly 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. 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, 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; not connected anteriorly to S-band, or connected anteriorly to S-band along vein R4+5 or in cell r2+3 (narrowly separated in holotype, probably sometimes narrowly connected); not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band. Apex of V-band extended from vein R4+5 to vein M, no hyaline area present between band and vein M. 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. Crossvein dm-cu orientation with anterior end more distal than posterior end.
Abdomen. Eversible membrane, subbasally on ventral side without cluster of hairs. Aculeus tip length 0.35–0.45 mm (0.40, Blanchard 1961); width 0.14–0.16 mm (0.15, Blanchard 1961); lateral margins not curved dorsally; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with fine serrations; serrated part 0.55–0.75 times length of tip (0.65, Blanchard 1961). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
Miscellaneous. Data source: Blanchard 1961. Data recording very inadequate. Sex of recorded specimens: female. Species group: not assigned to a species 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.
