Anastrepha bella Norrbom & Korytkowski View in CoL in Korytkowski 2004: 60 [nomen nudum; in key].

Diagnosis. Anastrepha bella differs from other species of Anastrepha by its distinctive wing pattern, which is entirely dark brown except for most of the C-band and a large medial area in the S-band in cells br and dm, which are yellow. It is unusual among predominantly brown-patterned species in that the distal part of the Cband, particularly the pterostigma, is much paler than the bands on the distal half of the wing. In the key of Steyskal (1977: 28), A. bella runs poorly to A. bondari Lima and A. tumida Stone which have predominantly orange wing patterns. It somewhat resembles A. bondari Lima, A. buscki Stone , and species of the doryphoros group in aculeus tip shape, but this similarity is probably superficial. Other useful diagnostic characters include: vein M weakly curved apically; mesonotum and abdomen without brown markings; and C-band and S-band, and S-band and V-band broadly connected.

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

Head: Yellow to orange except brown ocellar tubercle. 3–6 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most twice as long as ocellar tubercle. Facial carina, in profile, straight dorsally and medially. Antenna extended 0.75–0.90 distance to ventral facial margin.

Thorax ( Fig. 1 View FIGURES 1–4 ): Without brown markings. Mostly yellow to orange with following areas white or pale yellow (not always well differentiated in dried specimens): postpronotal lobe; medial scutal vitta, sometimes indistinct or absent, very slender, posteriorly not extended laterally beyond acrostichal seta; paired sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; entire scutellum; dorsal margin of anepisternum; katepimeron; and most of anatergite and katatergite. Posterior margin of scutum without darker band. Subscutellum and mediotergite entirely orange. Mesonotum 3.1–3.5 mm long. Scutum entirely microtrichose; setulae yellow to orange medially, brownish laterally. Katepisternal seta undifferentiated or small, weak, and yellowish.

Wing ( Figs. 20–21 View FIGURES 18–29 ): Length 6.8–8.4 mm, width 2.9–3.4 mm, ratio 2.33–2.55. Apex of vein R 1 at 0.51–0.55 wing length. Cell c 1.21–1.36 times as long as pterostigma; pterostigma 2.75–4.07 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.62–0.65 distance from bm-cu to dm-cu on vein M. Vein M slightly curved apically; cell r 4+5 1.03–1.28 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.53–1.73 times as long as anterior margin. Wing pattern mostly dark brown, yellow anterobasally. C-band entirely yellow except pterostigma sometimes orange to moderate brown, and distal margin in cells r 1 and r 2+3 and narrow streak in base of cell br dark brown; cell bc yellowish; cell c entirely yellow and entirely microtrichose. C-band and S-band broadly connected along vein R 4+5; hyaline area in cell br small, reaching vein R 4+5, but 0.57–1.10 times as long as distal colored area of cell; cell dm with basal hyaline area small to moderately large. Basal half of S-band dark brown except for large medial yellow area in cells br and dm from anterior end of r-m to or almost to vein Cu 1, proximally in cell dm without brown margin; with distinct incision in posterior margin in cell cu 1; remainder of S-band dark brown, including area near connection with V-band; distal section medium width to moderately broad, at apex of vein R 2+3 0.56–0.79 times width of cell r 2+3, even in width, well separated from apex of vein M; hyaline area proximal to it ending at vein R 2+ 3 in females, but usually not reaching it in males. Hyaline basomarginal spot in cell r 1 subtriangular with very blunt apex, broadly extended to R 4+5, its apex aligned proximal to crossvein r-m. V-band complete, entirely dark brown, very broadly connected to S-band in cell r 2+3; proximal arm slender anteriorly, broad posteriorly and with broad basal extension along wing margin, at level of vein M 1.50–1.67 times as wide as distal arm, 0.55–0.75 times as wide as hyaline area proximal to it in cells r 4+5 and dm; distal arm slender.

Abdomen: Mostly orange, without brown markings.

Male terminalia ( Figs. 211–212 View FIGURES 211–214 ): Lateral surstylus relatively long, extended beyond prensisetae by ca. 3.5 times length of prensiseta; in lateral view strongly posteriorly curved; in posterior view broad on basal half, rapidly tapered then nearly parallel-sided on short blunt apical lobe, lateral margin convex then concave, medial margin convex then straight to slightly concave. Proctiger with ventral and lateral sclerotized areas connected but lateral areas separate dorsally. Phallus 5.89–6.55 mm long, 1.9 times as long as mesonotum; glans 0.57–0.58 mm long.

Female terminalia: Oviscape ( Fig. 1 View FIGURES 1–4 ) 5.45–6.40 mm long, 1.73–2.02 times as long as mesonotum; brown except basal fifth ventrally and extreme base dorsally; spiracle at basal 0.20–0.28. Eversible membrane ( Figs. 64–65 View FIGURES 63–72 ) with ca. 60 hooklike dorsobasal scales in broad semicircular pattern. Aculeus ( Fig. 109 View FIGURES 108–130 ) straight or ventrally curved in lateral view, 4.76–5.85 mm long; in ventral view base only slightly expanded, 0.20–0.23 mm wide; shaft 0.16–0.17 mm wide at midlength; tip ( Fig. 166 View FIGURES 164–185 ) 0.22–0.24 mm long, 0.13–0.14 mm wide, 1.63–1.77 times as long as wide, 0.07–0.08 mm wide in lateral view, 0.53–0.59 times ventral width, in ventral view slightly broadened at base, rapidly tapering on basal third, then parallel-sided, and tapering on apical third, nonserrate. Spermathecae spherical.

Egg (25 dissected from abdomen of holotype): Slender, 2.15–2.25 mm long, 0.21–0.23 mm wide at broadest point, slightly curved. Posterior end strongly tapered. Anterior end without lobe distal to micropyle, micropyle nipple-shaped.

Distribution. Anastrepha bella is known only from Panamá.
