 Diagnosis. Anastrepha nigrifascia is similar to A. jamaicensis, A. simulans, and A. pseudorobusta 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. It differs from those three species in having large nonmicrotrichose areas on the scutum and the proximal arm of the V-band interrupted or constricted in cell r 4+5. It further differs from A. jamaicensis and A. simulans in having only one distal row of large hooklike denticles on the eversible membrane. It further differs from A. pseudorobusta in having shorter terminalia and a shorter aculeus tip.   
 Description. Mostly yellow to orange, with white to pale yellow markings. Setae dark orange brown to black.   
Head: Yellow to orange except brown ocellar tubercle. 3–7 (usually 4–5) frontal setae; 2 (rarely 3) orbital setae, posterior seta well developed. Ocellar seta weak, at most 1.5 times as long as ocellar tubercle. Facial carina, in profile, slightly concave to slightly convex (usually straight) dorsally and medially. Antenna extended 0.60–0.80 distance to ventral facial margin.  
Thorax (Fig. 9): Mostly yellow to orange with following areas white or pale yellow (not always well differentiated in dried specimens): postpronotal lobe; 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; most or all of 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, sometimes extended to but not completely including acrostichal seta, and ending laterally at sublateral white vitta, not extended to intra-alar seta. Scutellum with disc entirely white or yellow, often (especially in Bahamian specimens) with basal third or more of side (at most extending to apical seta) orange to medium brown. Subscutellum and mediotergite entirely orange. Mesonotum 2.87–3.40 mm long. Scutum largely nonmicrotrichose, microtrichia present medially (between acrostichal lines at and anterior to transverse suture, gradually broadening posteriorly to intra-alar seta) and laterally (on and lateral to sublateral vitta); setulae mostly yellow to orange, brownish laterally, or mostly brownish. Katepisternal seta weak, yellow to medium brown, at most 0.40 as large as anepimeral seta.  
 Wing (Figs. 47–49): Length 5.98–7.10 mm, width 2.4–2.9 mm, ratio 2.43–2.96. Apex of vein R 1 at 0.55–0.57 wing length. Cell c 1.22–1.38 times as long as pterostigma; pterostigma 3.14–4.10 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.64–0.69 distance from bm-cu to dm-cu on vein M. Vein M very strongly curved apically; cell r 4+5 0.83–0.94 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.50–1.64 times as long as anterior margin. Wing pattern mostly orange and moderate brown. C-band mostly orange; cells bc and c yellowish, cell c posteriorly with elongate subhyaline nonmicrotrichose area, anterodistal corner of cell c and all of pterostigma moderate brown; cells r 1, br, and r 2+3 orange except posterior and distal margins partially narrowly moderate brown. Cband and S-band narrowly connected along vein R 4+5, hyaline area in cell br large, elongate, reaching vein R 4+5, 1.5–3 times as long as distal orange area of cell; cell dm with basal hyaline area moderately large. Basal half of S-band relatively narrow, mostly orange, usually 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 with or without small incision in cell cu 1; distal section of band orange with brown margin in cell r 1, occasionally extending into cell r 2+3, entirely brown distally; relatively broad, at apex of vein R 2+3 0.71–0.93 times width of cell r 2+3, distinctly broadening in cell r 2+3, extended to apex of vein M; hyaline area proximal to it ending at vein R 2+3, often narrowed or rarely narrowly divided along vein R 4+5. Hyaline basomarginal spot in cell r 1 triangular, often narrow and/or with blunt apex, usually extended to R 4+5 (occasionally narrowly separated from vein), its apex aligned proximal to crossvein r-m. V-band entirely brown, proximal arm narrowed or more commonly interrupted in middle of cell r 4+5, at least distal arm narrowly connected to S-band in cell r 2+3; proximal arm moderately broad anteriorly, gradually slightly broadening posteriorly, without or with short basal extension along wing margin, at level of vein M 1.0–1.5 times as wide as distal arm and 0.9–1.3 times as wide as hyaline area proximal to it in cells r 4+5 and dm; distal arm moderately broad, often narrowed anteriorly.   
Abdomen: Mostly orange, without brown markings.  
Male terminalia (Figs. 203–204): Lateral surstylus short, extended beyond prensisetae by ca. 0.5 times length of prensiseta; in lateral view with apex blunt or with posterodistal margin concave; in posterior view lateral and medial margins convex, apex blunt. Proctiger with ventral and lateral sclerotized areas connected but lateral areas separate dorsally. Phallus 2.65–2.99 mm long, 0.84–0.92 times as long as mesonotum; glans 0.37–0.41 mm long.  
Female terminalia: Oviscape (Fig. 9) 1.91–2.23 mm long, 0.61–0.69 times as long as mesonotum; entirely orange; spiracle at basal 0.40–0.48. Eversible membrane (Figs. 82–83, 98) with 6–9 moderately long hooklike dorsobasal scales in 1 irregular row distal to similar number of small, stout scales. Aculeus (Figs. 128–129) straight in lateral view, 1.50–1.74 mm long; in ventral view base 0.21–0.29 mm wide; shaft 0.065 –0.075 mm wide at midlength; tip (Figs. 155, 176–177, 186) 0.22–0.26 mm long, 0.070 –0.075 mm wide, 3.29–3.71 times as long as wide, 0.07–0.08 mm wide in lateral view, 1.0–1.14 times ventral width, in ventral view parallelsided or very slightly expanded subbasally, then gradually tapered to relatively blunt apex, nonserrate. Spermathecae spherical.  
Egg (1 dissected from abdomen of female USA: Key Largo, USNMENT00216379): Very slender, 2.23 mm long, 0.13 mm wide at broadest point, slightly curved, subcylindrical, posterior end only slightly tapered. Anterior end with elongate lobe distal to micropyle 0.45 times as long as main part of egg.  
 Distribution. Anastrepha nigrifascia is known from the extreme southeastern USA (Florida Keys) and the Bahamas.   
 Biology. Stone (1942a) reported two species of Manilkara (Sapotaceae) as host plants of A. nigrifascia: M. jaimiqui (C. Wright) Dubard ssp. emarginata (L.) Cronquist [as Mimusops emarginata], and M. zapota (L.) P. Royen [as Achras zapota]. Only the former species is native to the known range of A. nigrifascia. The record from mango, Mangifera indica L., by Wasbauer (1972), based only on larvae and citing an unpublished list of R. H. Foote, is doubtful.
