### Anastrepha sagittata ? [Panama, South America]

Body. Setae orange brown, or red brown.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–7. 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 3.5–4.75 mm (3.70–4.68, n=16). Scutum mostly or entirely microtrichose. 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. Mesonotum yellow, or orange, or dark orange. Scutum presutural dorsocentral pale vitta absent; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end ovoid, or with posterior end broadly quadrate; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings, or with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum posteriorly with dark band or broad marking on posterior margin; without brown vittae, or with dark brown dorsocentral vitta (at most on posterior third). 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 8–11 mm (8.50–10.60, n=16). 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). 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; 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 connected. 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. 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 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; connected anteriorly to S-band along vein R4+5 or in cell r2+3. V-band distal arm complete, or incomplete, not reaching vein R4+5, but extended from vein M to wing margin; isolated, not connected to proximal arm of V-band or to S-band, or connected to proximal arm of V band. Vein R2+3 not sinuous; without accessory vein. Cell bcu posteroapical lobe shorter than vein A1+Cu2. 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. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view very short, barely extended beyond prensisetae, rounded apically. Lateral surstylus in posterior view not boot-shaped. Phallus length 0.8–1.2 mm; ratio (phallus length/mesonotum length) 0.16–0.3. Glans absent. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape straight; length 4.65–6.1 mm (4.74–5.97, n=15); length ratio (oviscape length/mesonotum length) 1–1.45 (1.03–1.39, n=14). Eversible membrane with dorsobasal denticles all small, weakly developed, in triangular to semicircular pattern. Aculeus length 4–5 mm (4.27–4.84, n=11). Aculeus length/oviscape length 0.7–0.9 (0.77–0.85, n=4). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length/aculeus length 0.02–0.06 (0.035–0.042, n=4). Aculeus tip length 0.13–0.2 mm (0.145–0.176, n=3; difficult to measure, proximal limit of tip difficult to distinguish); width 0.02–0.04 mm; lateral margins not curved dorsally; slender, with extreme apex sagittate; without ridges or lobes; without elongate dorsolateral depressions apically; with minute serration, visible only with compound microscope, or with fine serrations. Aculeus tip with serrations separated by less than width of serration. Spermathecae weakly sclerotized; ovoid.

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.
