### Anastrepha xanthochaeta Hendel

Body. Setae golden to pale orange, or orange.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–4. 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 with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 2.75–3.25 mm (3.0 in holotype, Stone 1942). Postpronotal lobe and notopleuron entirely microtrichose. Scutum microtrichose except paired elongate bare areas (with nonmicrotrichose paired vitta between acrostichal and dorsocentral lines). Scutellum disc entirely microtrichose. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length; postpronotal seta on posterior half of postpronotal lobe. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Mesonotum yellow, or orange. Scutum white areas not well differentiated in examined specimens. 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. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wings. Wing length 7.1–8.1 mm (7.6 in holotype, 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 and S-band separated. S-band extended anteriorly to vein R4+5 and covering all of crossvein r-m. S-band base without extension in middle of cell cu1 to posterior wing margin. V-band proximal arm as dark as apical half of S-band; 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 without accessory vein.

Abdomen. Abdominal tergite without brown markings. Glans present; without spinules. Oviscape length 2.3–2.8 mm (2.6 in holotype, Stone 1942). Aculeus length 2–2.4 mm (2.2 in holotype, Stone 1942). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip width 0.11–0.13 mm (0.12 in holotype, Stone 1942); length/width in ventral view 1.82, Stone 1942a, fig. 6b; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with fine serrations, or with medium sized serrations; serrated part 0.62, Stone 1942a, fig. 6b. Aculeus tip serrations 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: male and female. Species group: pseudoparallela group.

Biology and economic significance. This species is not considered economically significant. It has been reared from fruit of an undetermined species of Passiflora (Passifloraceae), but it has not been recorded from the commercially important species. Refer to the 'Tephritidae Databases' in the USDA Compendium of Fruit Fly Host Information (https://coffhi.cphst.org/) for host plant information.

Illustrations. • Wing. • Terminalia, female.

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.
