Anastrepha cocorae Norrbom & Korytkowski

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. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3, or produced between or just below antennae. Face with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 3–4.3 mm. Postpronotal lobe and notopleuron mostly or entirely nonmicrotrichose (sometimes with minute patches of microtrichia on posterior margin of notopleuron). Scutum nonmicrotrichose. Scutellum disc mostly or entirely without microtrichia. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length (usually stout in male); postpronotal seta on anterior 2/5 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; without pale spot or vitta on presutural lateral margin of scutum or posterior part of notopleuron. Scutum presutural dorsocentral pale vitta absent; with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end broadly quadrate, or with posterior end triangular (short, absent anterior to transverse suture, extended laterally to dorsocentral seta); pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum posteriorly with dark band or broad marking on posterior margin; 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, or yellow to red brown medially, dark brown laterally (with dark brown spot on lateral fourth or less of dorsal margin). Mediotergite entirely yellow to orange.

Wings. Wing length 8–10.7 mm. 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), or separated (narrowly by hyaline band distinctly narrowed along R4+5). Basal hyaline area between C-band and S-band extended to vein R4+5. Cell r1 basomarginal hyaline spot triangular to quadrate (recheck; add state for narrow?). 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 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; connected anteriorly to S-band along vein R4+5 or in cell r2+3; not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band, or isolated, not connected to proximal arm of V-band or to S-band (occasionally). 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) 0.66–0.85. Cell c: pterostigma ratio (cell c length/pterostigma length) 0.8–1. Vein R2+3 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) 0.67–0.72 (0.68–0.70). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 1.05–1.3 (1.06–1.27). Cell bcu ratio (length/anterior margin length along vein Cu) 1.4–1.7 (1.43–1.66). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view not boot-shaped. Surstylus in posterior view with mesal margin convex. Phallus length 8.4–9.3 mm; ratio (phallus length/mesonotum length) 2.16–2.8. Glans present. Oviscape straight; length 4.5–6.9 mm; length ratio (oviscape length/mesonotum length) 1.44–1.7; spiracle ratio (distance from base to spiracle/oviscape length) 0.25–0.31. Aculeus length 4.3–6.5 mm. Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.31–0.44 mm; width 0.11–0.13 mm; not flared outward at or proximal to base; with V-shaped ridge(s), in ventral view appearing notched or with small rounded projections laterally on basal half; with elongate dorsolateral depressions apically, tip triangular in apical view; not serrate; serrated part 0 times length of tip. Spermathecae ovoid, or elongate.
