 Anastrepha amazonensis Norrbom & Korytkowski in Korytkowski 2004: 58 [nomen nudum; in key].   
 Diagnosis. Anastrepha amazonensis differs from most species of Anastrepha in having an extension from the basal part of the S-band to the posterior wing margin in the middle of cell cu 1 that is not connected to the posterior end of the proximal arm of the V-band. It differs from the other species having that wing character in lacking hyaline areas in cells br and dm proximal to crossvein r-m. It differs from the other species except A. rafaeli in having the basomarginal hyaline area in cell r 1 aligned slightly distal to crossvein r-m.   
 Description. Mostly yellow to orange, with white to pale yellow markings. Setae dark red brown.   
Head: Yellow to orange except brown ocellar tubercle and U-shaped mark on posterior half of orbital plate and vertex, touching eye, connected only to posterior side of mark on ocellar tubercle. 3 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, 1.2 times as long as ocellar tubercle. Facial carina, in profile, straight dorsally and medially. Antenna extended 0.85 distance to ventral facial margin.  
Thorax: Mostly yellow to orange with following areas white or pale yellow (color pattern not well differentiated in holotype): postpronotal lobe; possibly an inverted T-shaped medial scutal vitta; paired sublateral scutal vitta from transverse suture to posterior margin, including intra-alar seta; entire scutellum; dorsal margin of anepisternum; katepimeron; and most of anatergite and katatergite. Posterior margin of scutum with broad brown band, broadest medially, including acrostichal seta and extended almost to dorsocentral seta, laterally with short anterior extension along sublateral white vitta. Subscutellum and mediotergite entirely orange. Mesonotum 2.70 mm long. Scutum entirely microtrichose; setulae mostly yellow to orange, brownish laterally. Katepisternal seta well developed, nearly as dark as and 0.67 times as large as anepimeral seta.  
 Wing (Fig. 19): Length 6.5 mm, width 2.7 mm, ratio 2.41. Apex of vein R 1 at 0.55 wing length. Cell c 1.19 times as long as pterostigma; pterostigma 3.15 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.65 distance from bm-cu to dm-cu on vein M. Vein M only slightly curved apically; cell r 4+5 1.33 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.63 times as long as anterior margin. Wing pattern mostly dark brown. C-band with cell bc yellowish to subhyaline; cell c narrowly yellowish basally and narrowly brown distally and on distal half of anterior margin, posteriorly with elongate medial subhyaline area, not extended into pterostigma or cell r 1; remainder of C-band dark brown. Cell c posteromedial nonmicrotrichose area small, less than half width of cell. C-band and S-band broadly connected along vein R 4+5 and basally, cell br and base of cell dm without hyaline areas. Basal half of S-band entirely brown, without orange area in cell dm or bordering crossvein r-m; with lobelike projection to posterior wing margin in middle of cell cu 1; distal section of band orange with brown margins, relatively broad, at apex of vein R 2+3 0.75 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 short triangular, extended slightly beyond vein R 2+3, its apex aligned slightly distal to crossvein rm. V-band complete, mostly brown, broadly connected to S-band in cell r 2+3; proximal arm with medial orange area bordering anterior 0.40 of dm-cu extending anteriorly beyond vein R 4+5; proximal arm very broad, gradually broadening posteriorly, without basal extension along wing margin, at level of vein M ca. 3 times as wide as distal arm and hyaline area proximal to it in cells r 4+5 and dm; distal arm slender. Abdomen: Mostly orange, without brown markings.   
Male terminalia: Unknown.  
Female terminalia: Oviscape 2.55 mm long, 0.94 times as long as mesonotum; base orange, distal three fourths brown; spiracle at basal 0.34. Eversible membrane (Fig. 63) with 20–25 large, hooklike dorsobasal scales in triangular pattern, gradually shorter and stouter proximally. Aculeus straight in lateral view, 2.24 mm long; in ventral view (Fig. 108) base 0.22 mm wide; shaft 0.12 mm wide at midlength; tip (Fig. 144) 0.26 mm long, 0.11 mm wide, 2.39 times as long as wide, 0.06 mm wide in lateral view, 0.55 times ventral width, in ventral view basal part nearly parallel-sided with lateral margin very slightly concave, apical 0.44 elongate triangular, finely serrate, but basal serrations curving onto dorsal side (difficult to see in ventral view). Spermathecae spherical.  
 Distribution. Anastrepha amazonensis is known only from Brazil (Amazonas).   
 Biology. The host plants and other aspects of the biology of this species other than date of capture of adults are unknown.   
 Type Data. Holotype female (INPA USNMENT00052107), BRAZIL: Amazonas: Manaus, 18 Oct 1985, B. Klein R-1301 R. e. s. 2. The holotype appears to have been preserved originally in alcohol and later pinned. Its eyes and scutum are slightly shriveled, making the color pattern of the latter difficult to observe.   
 Etymology. The name of this species is an adjective referring to the region where the holotype was collected.
