Anastrepha pseudoparallela (Loew)

Morphology

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. 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. Scutum nonmicrotrichose. 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, or absent. Mesonotum yellow, or orange. Scutum with 2 (sublateral) pale postsutural vittae; 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 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). Cell bm entirely hyaline or infuscated only along subapical fold. S-band base without extension in middle of cell cu1 to posterior wing 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; not connected anteriorly to S-band. V-band distal arm complete; connected to proximal arm of V band. Pterostigma ratio 3.8–4.5. Ratio of costa length between apices of Sc and R1/length between apices of R1 and R2+3 0.45–0.52. 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.

Abdomen. Abdomen ovate or parallel-sided, syntergite 1+2 gradually broadening or parallel-sided. Abdominal tergite without brown markings. Phallus length 3.9–4.2 mm; ratio (phallus length/mesonotum length) 1.15–1.25. Glans present; without spinules. Oviscape straight; length 2.95–3.5 mm; length ratio (oviscape length/mesonotum length) 0.8–1. Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus length 2.6–3.1 mm. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.35–0.5 mm; width 0.13–0.15 mm; gradually tapering, blade-like, with flattened cross-section; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with medium sized serrations, or with large serrations; serrated part 0.85–1.11 times length of tip. Aculeus tip serrations extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration. Spermathecae sclerotized. Egg without lobe (Figueiredo et al. 2011).
