Diagnosis. Anastrepha partita differs from most species of Anastrepha in having a posterior extension from the basal part of the S-band to the wing margin in the middle of cell cu 1 that is connected to the proximal arm of the V-band along the wing margin. It differs from the other species having that wing character by the following combination of characters: mesonotum and abdomen without brown markings; C-band and S-band and S-band and V-band broadly connected; vein M only slightly curved apically, cell r 4+5 1.09 times as wide at apex as at level of dm-cu; proximal arm of V-band with orange area bordering crossvein dm-cu broad and extending anteriorly to apex of band; does not extend into cell r 4+5; and C-band in cells r 1 and r 2+3 posterior to pterostigma with orange subapical area. A. partita is similar to A. nigra in having a very slender aculeus with a short tip, but A. nigra has longer terminalia with the distal part of the aculeus tip more distinctly constricted.

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

Head: Yellow to orange except brown ocellar tubercle. 3–4 frontal setae; 2 orbital setae, posterior seta well developed (frons setae lost on holotype, but size estimated from size of alveoli). Ocellar seta weak, small. Facial carina, in profile, straight dorsally and medially. Antenna extended 0.70 distance to ventral facial margin.

Thorax: Without brown markings. Mostly yellow to orange. Typical white or pale yellow areas (postpronotal lobe; paired sublateral scutal vitta from transverse suture to intra-alar seta; medial scutal vitta; entire scutellum; dorsal margin of anepisternum; katepimeron; and most of anatergite and katatergite) not well differentiated in holotype, probably present in live or fluid preserved material. Scutum orange medially, apparently without pale vitta; posterior margin without darker band. Subscutellum and mediotergite entirely orange. Mesonotum 3.82 mm long. Scutum entirely microtrichose; setulae mostly yellow to orange, brownish laterally. Katepisternal seta weak, only twice as long as setulae, yellow.

Wing ( Fig. 51 ): Length 8.58 mm, width 3.72 mm, ratio 2.31. Apex of vein R 1 at 0.54 wing length. Cell c 1.35 times as long as pterostigma; pterostigma 3.02 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.66 distance from bm-cu to dm-cu on vein M. Vein M only slightly curved apically; cell r 4+5 1.09 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.67 times as long as anterior margin. Wing pattern mostly orange and moderate brown. C-band with cell bc yellowish; cell c yellowish, base and anterior margin slightly darker, anterior margin brown distally, yellow area extended into posterobasal fifth of pterostigma and narrowly into adjoining part of cell r 1; remainder of pterostigma and distal margin in cells r 1 and r 2+3 moderate brown; section of br, r 1 and r 2+3 between fork of R 1 and Rs to level of midlength of pterostigma darker brown, somewhat mottled; subapical areas in r 1 and r 2+3 orange. C-band and S-band broadly connected along vein R 4+5; cell dm with basal hyaline area small but broadly reaching vein Cu 1. Basal half of S-band mostly orange anterior to vein Cu 1, with brown margins except for proximal margin in cell dm; 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 0.78 times width of cell r 2+3, slightly broadening in cell r 2+3, well separated from apex of vein M; hyaline area proximal to it ending at vein R 2+3. Hyaline basomarginal spot in cell r 1 triangular with blunt apex, distal side slightly elongated, extended to R 4+5, its apex aligned proximal to crossvein r-m. V-band complete, broadly connected to S-band in cell r 2+3, brown except orange apex, connection to S-band, and broad medial area in proximal arm from R 4+5 almost to posterior end of dm-cu; proximal arm broad anteriorly, gradually slightly broadening posteriorly, at level of vein M 1.6 times as wide as distal arm and hyaline area proximal to it in cells r 4+5 and dm; distal arm broad and nearly straight.

Abdomen: Mostly orange, without brown markings.

Male terminalia: Unknown.

Female terminalia: Oviscape 3.58 mm long, 0.94 times as long as mesonotum; distal half brown; spiracle at basal 0.29. Eversible membrane ( Fig. 85 ) with ca. 15 slender, sclerotized, hooklike dorsobasal scales in 2 irregular rows distal to several rows of shorter, weakly sclerotized scales. Aculeus ( Fig. 131 ) ventrally curved in lateral view, 2.76 mm long; in ventral view base 0.18 mm wide; shaft 0.04 mm wide at midlength; tip ( Figs. 157–158 ) 0.08 mm long, 0.03 mm wide, 2.67 times as long as wide, 0.03 mm wide in lateral view, 1.0 times ventral width, in ventral view with basal constriction, elongate oval, nonserrate. Spermathecae spherical.

Distribution. Anastrepha partita is known only from the Amazon region.

Biology. The host plants and other aspects of the biology of this species are unknown.

Type Data. Holotype female ( BMNH USNMENT00052108 ), with only the following labels: “Amazons.” and “ Trypeta ethalea Walker ”. There is no accession label. The type locality is presumably in Brazil: Pará or Amazonas or Peru: Loreto.

Etymology. The name of this species is a Latin adjective referring to the divided hyaline areas of the wing.
