Anastrepha jamaicensis Norrbom & Korytkowski View in CoL in Korytkowski 2004: 62 [nomen nudum; in key].

Diagnosis. Anastrepha jamaicensis is similar to A. nigrifascia , A. pseudorobusta , and A. simulans in having the C-band and S-band connected, vein M strongly curved apically, the S-band largely orange in cells br and dm-cu, and the aculeus straight and between 1–3 mm long with a nonserrate, awl-shaped tip about as broad in lateral view as in ventral view and between 0.2–0.4 mm long, 2.5–4.5 times as long as wide. In the key of Steyskal (1977: 25) it runs to A. nigrifascia . It differs from those three species in having the pterostigma distinctly darker than the brown areas of the S-band and V-band and in having the length/width ratio of the aculeus tip shorter (2.67 vs. greater than 3.0 in the other species). It further differs from A. nigrifascia in having the proximal arm of the V-band not interrupted nor constricted in cell r 4+5 and the distal arm widely separated. It further differs from A. nigrifascia and A. pseudorobusta in having 2 rather than one distal row of large hooklike denticles on the eversible membrane. The terminalia are longer than those of A. simulans (oviscape 2.42 mm long, 0.72 times as long as mesonotum, aculeus 1.92 mm long vs. 1.7–2.08 mm, 0.43–0.53 times mesonotum length, and 1.33–1.37 mm in A. simulans ).

Description. Mostly yellow to orange, with white to pale yellow markings. Setae dark brown to black.

Head: Yellow to orange except brown ocellar tubercle. 3–4 frontal setae; 2 orbital setae, posterior seta well developed (only 1 on right side of holotype between normal positions of anterior and posterior setae). Ocellar seta weak, 1.5 times as long as ocellar tubercle. Facial carina, in profile, straight dorsally and medially. Antenna extended 0.8 distance to ventral facial margin.

Thorax: Mostly yellow to orange with following areas white or pale yellow (not well differentiated in holotype): postpronotal lobe; diffuse inverted T-shaped medial vitta, posterior part extended laterally to dorsocentral seta; paired sublateral scutal vitta from transverse suture to posterior margin, including intra-alar seta; entire scutellum; dorsal margin of anepisternum; dorsal margin of katepisternum; katepimeron; and most of anatergite and katatergite. Posterior margin of scutum with broad dark brown band with more or less straight anterior margin, extended almost to acrostichal seta, ending laterally at sublateral white vitta, not extended to intra-alar seta. Subscutellum and mediotergite entirely orange. Mesonotum 3.38 mm long. Scutum entirely microtrichose; setulae mostly yellow, brownish laterally. Katepisternal seta weak, medium brown, 0.40 as large as anepimeral seta.

Wing ( Fig. 42 View FIGURES 42–53 ): Length 7.5 mm, width 2.9 mm, ratio 2.8. Apex of vein R 1 at 0.55 wing length. Cell c 1.13 times as long as pterostigma; pterostigma 3.41 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.70 distance from bm-cu to dm-cu on vein M. Vein M very strongly curved apically; cell r 4+5 0.85 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.53 times as long as anterior margin. Wing pattern mostly orange and moderate brown. C-band mostly yellowish to orange; anterodistal corner of cell c and all of pterostigma dark brown; posterior and distal margins including all of band in cell br moderate brown. C-band and S-band broadly connected along vein R 4+5, hyaline area in cell br moderate sized, elongate, reaching vein R 4+5, almost 2 times as long as distal orange area of cell; cell dm with basal hyaline area moderately large. Basal half of S-band mostly orange with narrow brown margins in radial cells and distally in cell dm, proximal margin in cell dm orange; mostly moderate brown in cell cu 1; posterior margin without incision in cell cu 1; distal section of band orange, with broad brown margin in cell r 2+3 and entirely brown in cell r 4+5; relatively broad, at apex of vein R 2+3 0.74 times width of cell r 2+3, even in width to very slightly broadening in cell r 2+3, extended to apex of vein M; hyaline area proximal to it ending at vein R 2+3. Hyaline basomarginal spot in cell r 1 triangular, extended to R 4+5, its apex aligned slightly proximal to crossvein r-m. V-band mostly brown, proximal arm broadly connected to Sband in cell r 2+3; proximal arm orange with narrow brown margins anterior to vein M and with slender orange area, narrowing posteriorly, bordering crossvein dm-cu; proximal arm moderately broad anteriorly, gradually broadening posteriorly, with basal extension along wing margin, at level of vein M 1.5 times as wide as distal arm and 1.4 times as wide as hyaline area proximal to it in cells r 4+5 and dm; distal arm moderately broad, widely separated from proximal arm, extending to vein R 4+5.

Abdomen: Mostly orange, without brown markings.

Male terminalia: Unknown.

Female terminalia: Oviscape 2.42 mm long, 0.72 times as long as mesonotum; entirely orange; spiracle at basal 0.41. Eversible membrane ( Fig. 77 View FIGURES 73–81 ) with 12 long hooklike dorsobasal scales in 2 irregular rows distal to similar number of small, stout scales. Aculeus ( Fig. 122–123 View FIGURES 108–130 ) straight in lateral view, 1.92 mm long; in ventral view base strongly expanded, 0.31 mm wide; shaft 0.08 mm wide at midlength; tip ( Figs. 151–152 View FIGURES 149–163 ) 0.24 mm long, 0.09 mm wide, 2.67 times as long as wide, 0.10 mm wide in lateral view, 1.11 times ventral width, in ventral view slightly expanded subbasally, then gradually tapered, nonserrate. Spermathecae spherical.

Distribution. Anastrepha jamaicensis is known only from Jamaica.
