### Anastrepha rosilloi Blanchard

Body. Setae red brown, or dark red brown.

Head. Occiput without brown marks. Face with ventral part gradually tapered laterally.

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 posteriorly without brown or orange brown markings. 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 6.75–8.25 mm (7.5, 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 covering base of cell r2+3; 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 in cell r1, narrowed along vein R4+5; 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. 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. Apex of V-band not extended from vein R4+5 to vein M, hyaline area present between band and vein M. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. 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. Oviscape length 4–4.9 mm (4.45, Blanchard 1961); spiracle ratio (distance from base to spiracle/oviscape length) 0.25–0.33 (0.29, Blanchard 1961). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with with 5 rows of hooks, Blanchard 1961. Aculeus length 3.85–4.75 mm (4.3, Blanchard 1961). Aculeus length/oviscape length 0.97, Blanchard 1961. Aculeus tip length 0.38–0.48 mm (0.43, Blanchard 1961); width 0.12–0.14 mm (0.13, Blanchard 1961); without ridges or lobes; without elongate dorsolateral depressions apically; with fine serrations, or with medium sized serrations; serrated part 0.45–0.67 times length of tip (0.56, 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 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.
