### Anastrepha pastranai Blanchard

Body. Setae orange brown, or red brown, or dark red brown.

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. Arista of male without preapical expansion. Palpus in lateral view evenly setulose.

Thorax. Mesonotum length 2.4–3.3 mm (2.5–3.18, n=8). Postpronotal lobe and notopleuron entirely microtrichose. Scutum mostly or entirely microtrichose. 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. Katepisternal seta moderately developed, larger than postocellar seta, but much smaller and weaker than anepimeral seta, or weak, no larger than postocellar seta, or absent. Mesonotum yellow, or orange. Scutum posteriorly without brown or orange brown markings (usually), or with only single medial brown spot on scuto-scutellar suture. 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 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 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 separated (by hyaline band narrowed along vein R4+5), 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. Cell bm entirely hyaline or infuscated only along subapical fold. S-band posterior margin without incision in cell cu1. 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. 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 (usually), or connected anteriorly to S-band along vein R4+5 or in cell r2+3; 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 (hyaline area very small), or extended from vein R4+5 to vein M, no 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. Area between S-band and V-band entirely microtrichose in cells dm and 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. 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. Abdominal tergite without brown markings. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view long, rounded apically. Lateral surstylus in posterior view not boot-shaped. Surstylus in posterior view with lateral margin convex. Surstylus in posterior view with mesal margin convex. Lateral surstylus in lateral view flattened, slightly curved, apex acute. Phallus length 2.75–3.4 mm (2.91–3.24, n=4); ratio (phallus length/mesonotum length) 1.10–1.13, n=4. Glans present; without spinules. Proctiger lateral and ventral sclerotized areas separate, lateral areas separate dorsally. Oviscape entirely yellow to orange brown; straight; length 2–2.6 mm (2.08–2.45, n=9); length ratio (oviscape length/mesonotum length) 0.7–0.9 (0.74–0.85, n=8). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 70–90 denticles (large hooklike denticles in numerous irregular rows in subtriangular pattern). Eversible membrane, subbasally on ventral side without cluster of hairs. Aculeus length 1.95–2.5 mm (2.06–2.37, n=9). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.32–0.42 mm (0.34–0.41, n=9); width 0.11–0.15 mm (0.12–0.14, n=9); lateral margins not curved dorsally; parallel-sided, then triangular, or triangular; 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 0.63–0.85 times length of tip (0.65–0.84, n=9). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration. Egg without lobe.

Miscellaneous. Sex of recorded specimens: male and female. Species group: pseudoparallela group.

Biology and economic significance. This species is may be a minor or potential pest of fruit of species of Passiflora (Passifloraceae), including P. quadrangularis L. and P. edulis Sims from which it has been reared. 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.
