Anastrepha teli Stone

Morphology

Body. Setae red brown, or dark red brown.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–5. 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. Palpus in lateral view evenly setulose.

Thorax. Mesonotum length 2.75–3.75 mm (3.50–3.55, n=3; 3.0–3.5, Stone 1942b). 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. Mesonotum yellow, or orange. Scutum with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end ovoid (extended laterally slightly beyond acrostichal seta); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings, or with only single medial brown spot on scuto-scutellar suture (usually with indistinct spot). 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 6.5–8.5 mm (7.71–8.04, n=2; 7.0–8.0, Stone 1942b). 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 (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, or connected anteriorly to S-band along vein R4+5 or in cell r2+3 (narrowly); 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. S-band distal section width ratio (width of S-band/width of cell r2+3, both measured perpendicular to costal margin at apex of vein R2+3) 0.6–0.85 (0.65–0.78, n=3). 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. Cell c: pterostigma ratio (cell c length/pterostigma length) 1.2–1.5 (1.25–1.43, n=3). Pterostigma ratio 3.1, n=1. Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.53–0.57 (0.55, n=2). 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. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.66–0.71 (0.67–0.70, n=3). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.8–0.95 (0.85–0.90, n=3). Cell bcu ratio (length/anterior margin length along vein Cu) 1.67–1.9 (1.75–1.83, n=2). Cell bcu posteroapical lobe longer than vein A1+Cu2. 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. Oviscape entirely yellow to orange brown; straight; length 2.5–3.3 mm (2.88–3.17, n=3; 2.68–3.00, Stone 1942b); length ratio (oviscape length/mesonotum length) 0.75–0.85 (0.81–0.90, n=3); spiracle ratio (distance from base to spiracle/oviscape length) 0.34–0.41 (0.36–0.39, n=3). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 25–30 denticles (long hooklike dorsobasal denticles in 3–4 irregular rows). Eversible membrane, subbasally on ventral side without cluster of hairs. Aculeus length 2.3–2.75 mm (2.52–2.65, n=2; 2.4–2.6, Stone 1942b). Aculeus length/oviscape length 0.82–0.9 (0.84–0.88, n=2). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length/aculeus length 0.1–0.12 (0.11, n=2). Aculeus tip length 0.21–0.31 mm (0.27–0.295, n=3; 0.22–0.28, Stone 1942b); width 0.13–0.17 mm (0.14–0.155, n=3); length/width in ventral view 1.74–2.03, n=3; depth (width in lateral view)/width (in ventral view) 0.46–0.48, n=2; lateral margins not curved dorsally; 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 0.5–0.65 times length of tip (0.54–0.61, n=3). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.
