Anastrepha fischeri Lima

Morphology

Body. Setae orange brown, or red brown, or dark red brown (red, Lima 1934).

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Orbital setae 2. 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. 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. Scutum without brown vittae. Scutellum entirely yellow or with dark markings only on extreme base of disk. Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange.

Wings. Wing length 6.5–8.5 mm (7.5, n=1, Stone 1942). 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 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; 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, or extended from vein R4+5 to vein M, no hyaline area present between band and vein M (possible variation, hyaline area very small in holotype). 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) 0.55–0.85 (0.69, estimated from Lima 1934, fig. 39). Cell c: pterostigma ratio (cell c length/pterostigma length) 1.15–1.45 (1.30, estimated from Lima 1934, fig. 39). Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.56–0.6 (0.58, estimated from Lima 1934, fig. 39). 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) 0.65–0.69 (0.67, estimated from Lima 1934, fig. 39). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.75–1 (0.88, estimated from Lima 1934, fig. 39). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Oviscape straight; length 2.2–2.6 mm (2.4, n=1, Lima 1934). Aculeus tip length 0.14–0.17 mm (0.15, estimated from Lima 1934, fig. 41); width 0.06–0.075 mm (0.067, estimated from Lima 1934, fig. 41); lateral margins not curved dorsally; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with medium sized serrations; serrated part 0.7–0.9 times length of tip (0.80, estimated from Lima 1934, fig. 41). Aculeus tip with serrations separated by less than width of serration.
