Diagnosis. Anastrepha robusta differs from other species of Anastrepha except A. amaryllis , A. fuscata , and A. furcata in having the aculeus strongly dorsally curved. It differs from those three species in the shape of the aculeus tip, with the lateral margins strongly concave. It further differs from A. fuscata and A. furcata in having the wing pattern more extensively orange, and from A. amaryllis in having shorter terminalia.

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

Head: Yellow to orange except brown ocellar tubercle. 3–6 (usually 4–5) frontal setae; 2 orbital setae, posterior seta well developed (very rarely absent; 1 of 102 specimens checked). Ocellar seta weak, at most twice as long as ocellar tubercle. Facial carina, in profile, slightly concave to slightly convex (usually straight) dorsally and medially. Antenna extended 0.55–0.75 distance to ventral facial margin.

Thorax ( Fig. 12 View FIGURES 10–13 ): 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, sometimes diffuse or reduced to quadrate posterior area 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 orange brown to dark brown band, at least slightly darker than other orange parts of scutum, with more or less straight anterior margin, at most extended to but not entirely including acrostichal seta, ending laterally at sublateral white vitta, not extended to intra-alar seta. Subscutellum and mediotergite entirely orange. Mesonotum 3.35–4.27 mm long. Scutum entirely microtrichose; setulae yellow to orange, brownish laterally. Katepisternal seta weak, yellow to medium brown, at most 0.40 as large as anepimeral seta.

Wing ( Figs. 56–57 View FIGURES 54–62 ): Length 7.06–8.87 mm, width 2.7–3.6 mm, ratio 2.44–2.66. Apex of vein R 1 at 0.52–0.55 wing length. Cell c 1.19–1.49 times as long as pterostigma; pterostigma 2.93–4.17 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.61–0.68 distance from bm-cu to dm-cu on vein M. Vein M very strongly curved apically; cell r 4+5 0.63–0.83 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.55–1.75 times as long as anterior margin. Wing pattern mostly orange and moderate brown. C-band mostly yellowish to orange; cell bc yellowish; cell c yellowish, base slightly darker, posteriorly sometimes with elongate subhyaline area; pterostigma mostly moderate brown, brown area sometimes extended into cell r 1; remainder of cells r 1, br, and r 2+3 orange except posterior and distal margins partially narrowly moderate brown. C-band and S-band narrowly to broadly connected along vein R 4+5, hyaline area in cell br moderately large, elongate, reaching vein R 4+5 or rarely [2 Veracruz specimens] very narrowly separated from it, 1.0–2.0 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; at least posterior half of part in cell cu 1 moderate brown; posterior margin with distinct incision in cell cu 1; distal section of band orange with brown margins between vein R 4+5 and costa and often more distally, entirely brown in cell r 4+5; medium width to moderately broad, at apex of vein R 2+3 0.62–0.85 times width of cell r 2+3, slightly to distinctly broadening in cell r 2+3, usually narrowly separated from apex of vein M, occasionally more separated or barely extended to it; hyaline area proximal to it usually ending at vein R 2+3, rarely (1 Panamanian female) narrowly separated from vein or occasionally (12 males, 1 female) extended slightly into cell r 1. Hyaline basomarginal spot in cell r 1 triangular, with blunt apex, often narrow, extended to R 4+5, its apex aligned proximal to crossvein r-m. Vband usually complete, mostly to entirely brown, connected, usually narrowly, to S-band in cell r 2+3; proximal arm often with medial orange area bordering part to entire length of dm-cu and extending to or beyond vein R 4+5, often interrupted; proximal arm slender anteriorly, gradually broadening posteriorly, usually with at least short basal extension along wing margin, at level of vein M 1.3–2.1 times as wide as distal arm and 0.55–1.0 times as wide as hyaline area proximal to it in cells r 4+5 and dm; distal arm slender, usually connected to proximal arm, sometimes narrowly, rarely (2 Costa Rican, 2 Guatemalan of 121 specimens examined) narrowly separated from proximal arm but reaching or almost reaching vein R 4+5.

Abdomen: Mostly orange, without brown markings.

Male terminalia ( Fig. 206 View FIGURES 205–210 ): 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 3.12–3.41 mm long, 0.76–0.93 times as long as mesonotum; glans 0.40–0.45 mm long.

Female terminalia: Oviscape 2.27–2.52 mm long, 0.57–0.63 times as long as mesonotum; entirely orange; spiracle at basal 0.35–0.46. Eversible membrane ( Figs. 91 View FIGURES 91–96 , 102 View FIGURES 101–107 ) with ca. 8–10 moderately long hooklike dorsobasal scales in 1 row distal to several row of smaller stout scales. Aculeus ( Figs. 138–139 View FIGURES 131–148 ) strongly dorsally curved ca. 45° in lateral view, 1.55–1.75 mm long; in ventral view base expanded, 0.18–0.25 mm wide; shaft 0.07–0.08 mm wide at midlength; tip ( Figs. 181 View FIGURES 164–185 , 187 View FIGURES 186–191 ) 0.21–0.26 mm long, 0.08–0.09 mm wide, 2.44–2.89 times as long as wide, 0.075–0.08 mm wide in lateral view, 0.83–1.00 times ventral width, in ventral view tapered, slightly expanded, then tapered to blunt apex, lateral margins concave, nonserrate. Spermathecae ( Fig. 105 View FIGURES 101–107 ) spherical.

Distribution. Anastrepha robusta is known from México (Veracruz, Oaxaca, Chiapas), Guatemala, Costa Rica, and Panamá. Records from Venezuela and Brazil were based on misidentifications. The paratype from Venezuela is A. pseudorobusta . Stone (1942a: 91) suggested that the female of A. furcata from Rio Cumina, Brazil recorded by Lima (1937b) is A. robusta , but according to Zucchi (1978: 55) it is in fact A. furcata .

Biology. The host plants of this species are unknown. Aluja (1993) reported observations on the calling behavior of the male.

Type Data. Holotype female ( USNM USNMENT000104285 About USNM ), Guatemala: Cayuga , Jul 1915, W. Schaus [examined]. The wings of the holotype are rather tattered and there is a large crack in its scutum. The terminalia are mounted on slide 36.III.13c.
