Diagnosis. Anastrepha grandicarina differs from most other species of Anastrepha in having a “grandis-type” wing pattern, that is, with the C-band and S-band broadly fused so that there is no hyaline marginal mark in cell r1, the S-band complete, and the distal arm of the V-band absent. In the key of Norrbom (1991), who revised the species with this type of pattern, it runs to couplet 5. It differs from the two species in that couplet in having longer terminalia (oviscape more than 9 mm long vs. less than 5 mm in A. grandicula Norrbom and A. castilloi Norrbom). It differs from all species with this type of wing pattern in having the facial carina strongly protuberant medially, in this respect resembling Anastrepha superflua Stone and a few other species, all of which have the distal arm of the V-band present. Additional useful diagnostic characters include: greater ampulla orange, without brown spot; medial scutal vitta ovoid posteriorly, not extended laterally to dorsocentral seta; cell cell r2+3 with large subapical hyaline area; abdominal tergites without brown markings; eversible membrane with hooklike dorsobasal denticles in 4–5 irregular rows in subtriangular pattern; and aculeus tip with distal two-fifths triangular and finely serrate, and the proximal part of the tip narrower than the serrate part.
Description. Mostly yellow to dark orange. Setae red brown (usually dark red brown) to black.
Head (Fig. 19): Yellow to orange except brown ocellar tubercle. 3-5 (usually 4) frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 1.5 times as long as ocellar tubercle. Facial carina, in profile, with strong convex protuberance near mid height, protuberance with narrow median longitudinal indentation. Antenna not extended to ventral facial margin. Palpus in lateral view dorsally curved, evenly setulose.
Thorax: Mostly orange to dark orange, with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it, not extending onto notopleuron; medial scutal vitta, slender except posterior sixth slightly expanded and rounded, extended laterally to or slightly beyond acrostichal seta but not to dorsocentral seta; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; scutellum except sometimes extreme base; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Subscutellum and mediotergite orange medially, dark brown laterally. Mesonotum 4.06–4.73 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae mostly brownish, yellowish medially. Chaetotaxy typical for genus. Katepisternal seta weak, at most half as long as anepisternal seta, but much weaker, orange.
Legs: Entirely yellow to orange.
Wing (Fig. 28): Length 9.51–11.30 mm, width 3.65–4.06 mm, ratio 2.61–2.71. Apex of vein R1 at 0.55–0.56 wing length, distinctly proximal to level of anterior end of crossvein r–m. Cell c 1.21–1.30 times as long as pterostigma; pterostigma 3.88–4.63 times as long as wide. Vein R2+3 not sinuate. Crossvein r–m at 0.71–0.73 distance from bm–cu to dm–cu on vein M. Vein M strongly curved apically; cell r4+5 0.81–0.90 times as wide at apex as at level of dm–cu. Cell bcu with distal lobe moderately long, length of bcu 1.50–1.57 times as long as anterior margin, lobe 0.67–0.71 times as long as vein A1+Cu2. Wing pattern mostly orange and orange brown. Cband mostly orange, orange brown in pterostigma and most of basal half of cell br. C-band and S-band extremely broadly connected between costa and vein R4+5; cell r1 without marginal hyaline area distal to apex of vein R1. Hyaline area in cell br narrow, narrowly separated from vein R4+5 and 1–2 times as long as distal colored area of cell; cell dm with basal hyaline area relatively small. Basal half of S-band mostly orange, posterodistal margin brown, very broadly in cell cu1, without incision in cell cu1; distal section orange gradually changing to orange brown apically, moderately broad, at apex of vein R2+3 0.66–0.67 times width of cell r2+3, not extended to apex of vein M; hyaline area proximal to apex of band extending to or almost to vein R2+3. V-band incomplete; proximal arm mostly moderate brown, orange bordering crossvein dm–cu and in most of part in cell r4+5, separate from Sband anteriorly, on posterior margin extended approximately four-fifths distance to vein A1+Cu2; distal arm absent or (Perú female paratype) reduced to diffuse spot posterior to vein M.
Abdomen: Mostly orange, without brown markings. Setulae orange medially, brownish laterally.
Male terminalia (Figs. 102, 103): Lateral surstylus relatively long, extended beyond prensisetae by 4 times length of prensiseta; in lateral view slightly posteriorly curved, rapidly tapering to acute apex; in posterior view broad, lateral and medial margins convex, sometimes straight or slightly concave subapically. Proctiger with ventral and lateral sclerotized areas very narrowly connected apically but lateral areas separate dorsally. Phallus 15 mm long, 3.7 times as long as mesonotum; glans 0.65 mm long, 0.04 times as long as phallus.
Female terminalia: Oviscape 9.35–11.72 mm long, 2.28–2.48 times as long as mesonotum, straight in lateral view, brown except basally, orange extending to slightly beyond spiracle ventrally, about half way to spiracle dorsally; spiracle at basal 0.17–0.19. Eversible membrane (Fig. 51) with 30–35 hooklike dorsobasal denticles in 4–5 irregular rows in subtriangular pattern. Aculeus (Fig. 72) slightly ventrally curved in lateral view, 11.0 mm long in dissected paratype, 1.0 times as long as oviscape, in ventral view base slightly expanded, 0.23 mm wide; shaft 0.12 mm wide at midlength; tip (Fig. 86) 0.56 mm long, 0.05 times aculeus length, 0.17 mm wide, 3.29 times as long as wide; aculeus narrowed just before base, slightly expanded and evenly rounded at base, then narrowed and expanded (lateral margin convex), apical 0.41 triangular and finely serrate, 1.35 times as long as wide. Spermathecae ovoid.

Etymology. The name of this species is a Latin noun meaning large carina, in reference to the protuberant facial carina.
Comments. Anastrepha grandicarina is tentatively placed in the grandis species group based on its wing pattern, although it resembles some species of the benjamini group and the A. pallidipennis complex (see Norrbom 1997) in the shape of the facial carina.
