### Anastrepha freidbergi Norrbom

Body. Setae dark red brown, or dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–6. Orbital setae 2 (posterior seta often weak). 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 3.75–4.85 mm (3.85–4.74, n=5). Scutum microtrichose except paired elongate bare areas (with very narrow paired nonmicrotrichose vitta lateral to acrostichal line, extended posteriorly at least to level of postsutural supra-alar seta but not beyond midpoint between transverse suture and posterior scutal margin). 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 weak, no larger than postocellar seta. Mesonotum orange, or dark orange, or orange brown. Scutum presutural dorsocentral pale vitta absent; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta narrow posteriorly, not expanded (not extended laterally to acrostichal seta); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. 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 brown to dark brown, or yellow to red brown medially, dark brown laterally. Mediotergite entirely brown to dark brown, or yellow to red brown medially, dark brown laterally.

Wings. Wing length 10–12.5 mm (10.40–12.18, n=5). 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), or without typical bands (bands diffuse and extensively fused, may be difficult to recognize). Cell c mostly or entirely infuscated to subhyaline, or paler posteriorly, without distinct subapical hyaline area. C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3. C-band and S-band connected (broadly along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended into cell br but not reaching vein R4+5 (hyaline area tiny if present), or not extended into cell br. Cell r1 basomarginal hyaline spot semicircular to subovoid. Cell r1 basomarginal hyaline spot apex aligned with crossvein r-m, or apex aligned distal to crossvein r-m. 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; without extension in cell a1 to or almost to posterior margin. Subapical hyaline area in radial cells distal to r-m S-band entirely covering cell r2+3 distal to r-m (present only in r4+5 or absent). S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. V-band proximal arm as dark as apical half of S-band; broadly connected anteriorly to S-band along vein R4+5 or in cell r2+3; connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V-band and broadly connected with apical part of S-band (separated from S-band only in cell r4+5). 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) 1. 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. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.7–0.75 (0.71–0.74, n=5). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Epandrium posterodorsal margin produced medially. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view not boot-shaped. Phallus length 20.5–24 mm (22.0–22.7, n=3); ratio (phallus length/mesonotum length) 4.9–5.8 (5–5.71, n=3). Glans present; without spinules. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape straight; length 12.5–15.5 mm (13.83–14.65, n=2); length ratio (oviscape length/mesonotum length) 2.85–3.2 (2.92–3.12, n=2). Eversible membrane with dorsobasal denticles all sclerotized, relatively small, in very elongate pattern. Aculeus length 11.3–14.5 mm (12.34, n=1). Aculeus length/oviscape length 0.85–0.95 (0.89, n=1). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length/aculeus length 0.02–0.05 (0.04, n=1). Aculeus tip length 0.44–0.54 mm (0.49, n=1); width 0.13–0.15 mm (0.14, n=1); length/width in ventral view 3.5, n=1; lateral margins not curved dorsally; tapered basally, then parallel-sided, then gradually tapered; 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. Spermathecae sclerotized; ovoid, or elongate.

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.
