Anastrepha apicata Norrbom & Korytkowski

Morphology

Body. Setae dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 2–4 (usually 3). Orbital setae 2 (usually), or 1. Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile 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 3.9–4.8 mm. Postpronotal lobe and notopleuron mostly or entirely nonmicrotrichose. 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; postpronotal seta on posterior half of postpronotal lobe. Acrostichal seta well developed, or absent. Basal scutellar seta strong, longer than scutellum. Katepisternal seta weak, no larger than postocellar seta (usually), 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 2 (sublateral) pale postsutural vittae; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings. 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.

Wings. Wing length 10.3–13 mm. Wing pattern with only a large, subapical brown spot, pale brown pterostigma, and diffuse yellow markings in cells bc, c, br, r1 and r2+3. Cell bm entirely hyaline or infuscated only along subapical fold. S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. V-band proximal arm absent or diffuse and much paler than apical half of S-band. V-band distal arm absent. Cell c: pterostigma ratio (cell c length/pterostigma length) 1–1.22. 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) 0.6–0.66 (0.61–0.65). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.9–1.1 (0.90–1.08). Cell bcu ratio (length/anterior margin length along vein Cu) 1.25–1.4 (1.27–1.37). 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 12–18 mm; ratio (phallus length/mesonotum length) 3–4. Glans present. Oviscape straight; length 9–11.5 mm; length ratio (oviscape length/mesonotum length) 2.15–2.5 (2.19–2.48); spiracle ratio (distance from base to spiracle/oviscape length) 0.24–0.28. Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus length 8–10 mm (8.4–9.8). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.49–0.55 mm; width 0.15–0.17 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; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip. Egg without lobe.
