Anastrepha relicta Hernández-Ortiz

Morphology

Body. Setae dark brown to black.

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 ("short but slightly more developed and stout than in other Anastrepha species", Hernández-Ortiz 2004). Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face without brown markings.

Thorax. Mesonotum length 2.8–3.45 mm (3.11–3.15, Hernández-Ortiz 2004). Scutum nonmicrotrichose (except postsutural lateral 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. Mesonotum yellow, or orange, or dark orange. Scutum "medial yellow stripe indistinct, sublateral yellow stripes present", Hernández-Ortiz 2004. Scutum posteriorly with pair of brown spots or markings. Scutum posteriorly with only pair of brown spots posteroventral to and between intra-alar and postalar setae; without brown vittae. Scutellum entirely yellow or with dark markings only on extreme base of disk. Subscutellum yellow to red brown medially, dark brown laterally. Mediotergite entirely yellow to orange.

Wings. Wing length 7.5–9.4 mm (8.36–8.47, Hernández-Ortiz 2004). 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. C-band and S-band separated (by hyaline band from cell bm to costal margin). 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. 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; not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band. Apex of V-band extended from vein R4+5 to vein M, no hyaline area present between band and vein M. Vein R2+3 without accessory vein. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Phallus length 3.09, Hernández-Ortiz 2004. Glans present. Oviscape length 2.9–3.4 mm (3.15, Hernández-Ortiz 2004); ratio (oviscape length/mesonotum length) 0.9–1.1 (1.00–1.01 based on Hernández-Ortiz 2004). Eversible membrane with dorsobasal denticles with approximately 15 hook-like denticles, moderately developed, in single row forming semicircular line, Hernández-Ortiz 2004.
