Anastrepha enkerlini Hernández-Ortiz

Morphology

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

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–5 (4–5, Hernández-Ortiz 1999). 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.

Thorax. Mesonotum length 3.25–3.95 mm (3.35–3.85, Hernández-Ortiz 1999). 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 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 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 length 8–9.7 mm (8.12–9.54, Hernández-Ortiz 1999). 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 filling all of band in cells r1 and r2+3, or broad, extending distally into cells r1 and r2+3 at least to level of midlength of pterostigma. C-band and S-band separated (broadly by hyaline band from cell bm to costal margin in cell r1). 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 into cell r1, or 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 not extended from vein R4+5 to vein M, 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. Surstylus in posterior view with mesal margin convex. Lateral surstylus in lateral view flattened, slightly curved, apex acute. Glans present; without spinules. Oviscape entirely yellow to orange brown; straight; length 2.7–3.45 mm (2.78; 2.80–3.39, Hernández-Ortiz 1999); length ratio (oviscape length/mesonotum length) 0.75–0.95 (0.85, n=1); spiracle ratio (distance from base to spiracle/oviscape length) spiracle 0.95–1.19 mm from base, Hernández-Ortiz 1999. Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane, subbasally on ventral side without cluster of hairs. Aculeus length 2.33–2.95 mm (2.41–2.90, Hernández-Ortiz 1999). Aculeus length/oviscape length 0.96, n=1. Aculeus in lateral view straight or ventrally curved. Aculeus tip length/aculeus length 0.08–0.12 (0.10, n=1). Aculeus tip length 0.24–0.32 mm (0.255, n=1; 0.27–0.31, Hernández-Ortiz 1999); width 0.16–0.2 mm (0.18, n=1; 0.17–0.19, Hernández-Ortiz 1999); length/width in ventral view 1.25–1.6 (1.42, n=1); depth (width in lateral view)/width (in ventral view) 0.15–0.3 (0.22, n=1); lateral margins not curved dorsally; flared outward at or proximal to base, lateral margin strongly concave; without ridges or lobes; without elongate dorsolateral depressions apically; with fine serrations; serrated part 1–1.2 times length of tip (1.10, n=1). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
