Diagnosis. Anastrepha pittieri differs from most species of Anastrepha in having an extension from the base of the S-band in the middle of cell cu 1 that is connected to the proximal arm of the V-band on the posterior wing margin. It differs from other species having that wing character, except A. isolata , in having vein M strongly curved apically and the C-band with a well defined, yellow or subhyaline area in cell r 1 posterior to the basal third to half of the pterostigma. It differs from A. isolata in having the aculeus tip not expanded basally and with smaller serrations.

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 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, slightly concave to slightly convex (usually straight) dorsally and medially. Antenna extended 0.7–0.8 distance to ventral facial margin.

Thorax: Mostly yellow to orange with following areas white or pale yellow (not always well differentiated in dried specimens): postpronotal lobe; diffuse medial vitta, inverted T-shaped 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; part 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 brown band with straight anterior margin or narrowest medially, where not extended anteriorly beyond acrostichal seta, sometimes with short anterior extensions towards or to dorsocentral seta or laterally along sublateral white vitta, ending laterally at sublateral white vitta, not extended to intra-alar seta; occasionally extended onto extreme base of disc of scutellum or (1♂ 1♀ Rancho Grande) with scutellum, including sides, largely pale brown except large medial white area on disk and apex and smaller lateral white area including basal seta. Subscutellum and mediotergite entirely orange. Mesonotum 4.00– 4.35 mm long (3.88–4.36 according to Caraballo 1985). Scutum entirely microtrichose; setulae yellow or orange medially, brownish laterally, or mostly brownish. Katepisternal seta weak, yellow or orange, no more than 0.33 as large as anepimeral seta.

Wing ( Fig. 53 View FIGURES 42–53 ): Length 8.9–10.6 mm, width 3.6–4.1 mm, ratio 2.40–2.63. Apex of vein R 1 at 0.54–0.57 wing length. Cell c 1.14–1.31 times as long as pterostigma; pterostigma 3.18–4.07 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 strongly curved apically; cell r 4+5 0.61–0.81 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.58–1.82 times as long as anterior margin. Wing pattern mostly moderate to dark brown and orange. C-band with cell bc yellowish; cell c yellowish basally and anteriorly, distal 0.20–0.75 of anterior margin brown, posteriorly with elongate medial subhyaline or hyaline area; yellow area sometimes extending into posterobasal corner of pterostigma and always into cell r 1, broadly reaching or usually almost reaching R, and extending distally to level of 0.33–0.67 length of pterostigma; remainder of band in pterostigma, r 1, r 2+3, and br dark brown except pterostigma sometimes paler brown apically or r 1 and/or r 2+3 sometimes with dark orange brown subapical areas. C-band and S-band broadly connected along vein R 4+5; hyaline area in cell br small, usually not reaching vein R 4+5 and 0.50–1.33 times as long as distal orange and brown area of cell; cell dm with basal hyaline area moderately large. Basal half of S–band mostly brown, with large medial orange area broadly bordering crossvein r-m and extending into anterior 0.50–0.80 of cell dm, proximal margin of band in dm with brown margin except in Rio Caruai female; with brown, lobelike projection to posterior wing margin in middle of cell cu 1 broadly connected to proximal arm of V-band along wing margin; distal section of S-band orange with broad brown margins, moderately broad, at apex of vein R 2+3 0.62–0.83 times width of cell r 2+3, even in width to distinctly 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 narrowly triangular, sometimes with blunt apex, extended to R 4+5, its apex aligned proximal to crossvein r-m. V-band complete, mostly brown, broadly connected to S-band in cell r 2+3; proximal arm with slender medial orange area bordering anterior half to entire length of dm-cu and extending into cell r 4+5, usually reaching to or beyond vein R 4+5; proximal arm moderately broad anteriorly, slightly gradually broadening posteriorly, with basal extension along wing margin, at level of vein M 1.4–2.0 times as wide as distal arm and 1.20–1.75 times as wide as hyaline area proximal to it in cells r 4+5 and dm; distal arm slender to moderately broad, connected to proximal arm.

Abdomen: Mostly orange, without brown markings.

Male terminalia ( Figs. 207–208 View FIGURES 205–210 ): Lateral surstylus short, extended beyond prensisetae by ca. 1.5 times length of prensiseta; in lateral view slightly posteriorly curved; in posterior view gradually tapered to bluntly acute apex, lateral margin slightly convex to slightly concave, medial margin convex. Proctiger with ventral and lateral sclerotized areas connected but lateral areas separate dorsally. Phallus 2.30–2.40 mm long, 0.54–0.58 times as long as mesonotum; glans 0.41–0.50 mm long.

Spermathecae spherical.

Egg ( Fig. 190 View FIGURES 186–191 ) (8 dissected from abdomen of female, Venezuela: Rancho Grande): Slender, 1.38–1.55 mm long, 0.15–0.18 mm wide at broadest point, slightly curved, subcylindrical, posterior end only slightly tapered. Anterior end with elongate lobe distal to micropyle 0.63 times as long as main part of egg, micropyle nipple-shaped.

Distribution. Anastrepha pittieri is known from Panamá and Venezuela (Aragua, Bolívar). The record from Brazil (Amazonas) ( Silva & Ronchi-Teles 2000) was based on a male of A. isolata misidentified by Norrbom.

Biology. The host plants and other aspects of the biology of this species other than dates of capture of adults are unknown.

Comments. This species was well described by Caraballo (1985) and we examined paratypes . One female (USNMENT00216184) and one male (USNMENT00216182) from Rancho Grande , Venezuela have an unusual scutellum color, with the base of the disk brown, extending to the sides between the basal and apical setae, isolating a broad oval yellow medial area. These specimens have the posterior scutal band relatively dark, so this may be the full expression of this species' color pattern. The female from the Caruai River has the least serrate aculeus tip and several slight differences in wing pattern, but is tentatively considered conspecific with the other specimens .
