Anastrepha bezzii Lima

Recognition
Anastrepha bezzii differs from all other Anastrepha species in its elongate pattern of toothlike scales on the eversible membrane, and in the shape of the aculeus tip. Species of the doryphoros group have a somewhat similar pattern of eversible membrane scales, but not as elongate and with the scales themselves much shorter. Anastrepha bezzii differs from most Anastrepha species in having a complete S-band that is broadly fused to the C-band along the costa, so that there is no hyaline area in cell r₁ distal to the apex of vein R₁. It differs from the other species with this type of wing pattern in having a hyaline area in cell r₂₊₃ between crossveins BM-Cu and R-M; the section of vein M between BM-Cu and R-M less than 1.85 times as long as section between R-M and DM-Cu; and vein R₂₊₃ usually undulant.

Description
Body mostly yellowish to orange. Setae red brown to dark red brown.

Head: Concolorous except dark brown ocellar tubercle; 2-4 frontal setae; 1 (rarely 2) orbital seta (posterior seta present, only on left side, in only 1 of 38 specimens examined). Antenna extends 0.50 distance to lower facial margin.

Thorax: Mesonotum 3.66-4.52 mm long (up to 5.00 in Brazil (Zucchi 1984)). Scutum entirely microtrichose; mostly yellowish to orange with indistinct whitish or transluscent areas; pattern difficult to see, but transluscent medial stripe hardly expanded until about half way between transverse suture and posterior margin, and then abruptly so; posterior part of medial stripe larger and more rectangular than in castilloi, fusing with narrow transluscent stripe extending from anterior margin in line with dorsocentral seta; scuto-scutellar suture without distinct medial dark brown spot. Subscutellum and mediotergite entirely yellow to orange. Pleura with typical dark areas poorly differentiated. Katepisternal seta undifferentiated or weak, yellowish, no longer than postocellar seta.

Wing: Length 8.39-10.29 mm (up to 10.75 in Brazil (Lima (1937)). Vein R₂₊₃ almost straight to strongly undulant. Vein M strongly curved apically, reaching apex of S-band; section between bm-cu and r-m 1.48-1.79 times as long as section between r-m and dm-cu. Pattern faint yellow to faint orange brown, its margins often diffuse. Cells dm, br and r₂₊₃ crossed by hyaline area between bm-cu and r-m, rarely narrowly entering cell r₁. Cell r₂₊₃ also with large subapical hyaline area. Cell bm hyaline. Proximal arm of V-band strong until vein M, usually extending faintly to R₄₊₅; separate from S-band.

Abdomen: Tergites unicolorous yellowish to orange.

Male terminalia: Lateral surstylus strongly delimited from epandrium, broad basally, gradually tapering to rounded apex; relatively short, section apical to apex of inner surstylus 0.60-0.70 times as long as basal part; posterior side slightly concave. Proctiger without distinct lateral fold; sclerotized part undivided. Phallus 9.71-12.10 mm long; 2.56-2.83 times as long as mesonotum. Glans 0.65-0.80 mm long, relatively stout; acrophallus strong, moderately broad, but not distinctly convoluted apically, a subapical hooklike structure usually apparent.

Female terminalia: Oviscape 6.28-9.55 mm long (as short as 5.56 mm in Venezuela (Caraballo 1981), up to 12.50 mm in Brazil (Lima 1937)); 1.63-2.16 times as long as mesonotum (up to 2.63 times in Brazil (Lima 1937)). Eversible membrane with dorsobasal scales in elongate pattern 1.85-3.33 mm long (up to 4.00 in Brazil (Zucchi 1984)); largest scales at basal third, 0.08-0.09 mm long. Aculeus 5.62-9.13 mm long (up to 10.00 in Brazil (Zucchi 1984)); tip 0.25-0.35 mm long, 0.09-0.10 mm wide, non-serrate, sides slightly convex, ventral surface transversely concave with apical 1/5 slightly convex. Spermathecae weakly sclerotized, elongate ovoid.
