Anastrepha tripunctata Wulp

Morphology

Body. Setae red brown, or dark red brown.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 2–4 (3 in type specimens). Orbital setae 2. Ocellar seta well developed. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face without brown markings. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 2.2–2.7 mm (2.38–2.50, n=2, Norrbom 1985). Scutum nonmicrotrichose (except postsutural lateral margin). 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 posteriorly without brown or orange brown markings, or with pair of brown spots or markings. Scutum posteriorly with only pair of brown spots posteroventral to and between intra-alar and postalar setae; without brown vittae. Scutellum yellow, apex with brown medial spot. Mesopleuron mostly yellow to orange, without brown markings. Subscutellum yellow to red brown medially, dark brown laterally. Mediotergite entirely yellow to orange.

Wings. Wing length 4.8–5.7 mm (5.15–5.40, n=2, Norrbom 1985). 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 R2+3, cell r1 with small basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended anteriorly beyond vein R4+5. Cell r1 basomarginal hyaline spot triangular to quadrate. Cell r1 basomarginal hyaline spot apex aligned proximal to crossvein r-m, or apex aligned with crossvein r-m, or apex aligned distal 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 with distinct 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, or extending into cell r2+3 but not reaching 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, or with very narrow marginal hyaline band in cell r2+3 or with small marginal hyaline spot(s) near apices of veins R2+3 and/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. Apex of V-band extended from vein R4+5 to vein M, no hyaline area present between band and vein M. Vein R2+3 not sinuous; without accessory vein. 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. Lateral surstylus in posterior view not boot-shaped. Surstylus in posterior view with lateral margin convex. Surstylus in posterior view with mesal margin convex. Phallus length 2–2.25 mm (2.13, n=1, Norrbom 1985). Glans present; without spinules. Oviscape straight; length 1.3–1.7 mm (1.50, n=1, Norrbom 1985); length ratio (oviscape length/mesonotum length) 0.5–0.7 (0.60, n=1, Norrbom 1985); spiracle ratio (distance from base to spiracle/oviscape length) 0.3–0.35 (0.33, n=1, Norrbom 1985). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 25–40 denticles (slender, moderate sized hooklike dorsobasal denticles in triangular pattern). Aculeus length 1.1–1.35 mm (1.21, n=1,). Aculeus length/oviscape length 0.81, n=1, Norrbom 1985. Aculeus tip length 0.04–0.06 mm (0.05, n=1, Norrbom 1985); lateral margins not curved dorsally; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip.
