Anastrepha normalis Norrbom

Recognition
Anastrepha normalis is one of the species of the serpentina group with a hyaline area in cell br posterior to the pterostigma that is not extended to vein R4+5. It differs from the other species with this character in having a paler wing pattern. In particular, the middle section of the S-band anterior and distal to crossvein R-M is orange brown with only narrow dark brown margins. A. normalis further differs from all of these species, except A. ornata Aldrich and one female of A. anomala Stone (Maranhão, Brazil) in lacking fine serrations on the aculeus tip. It is most likely to be confused with A. anomala or A. pseudanomala Norrbom, from which it further differs in having the aculeus tip less than twice as long as wide. It differs further from A. anomala in lacking the basolateral lobe on the lateral surstylus and from A. pseudanomala in having the distal section of the S-band slightly broader and sometimes touching the apex of vein M.

Description
Body largely dark orange to dark red-brown with yellow markings. Setae dark brown.

Head: Yellow except ocellar tubercle brown. Facial carina, in profile, concave. 3-5, usually 4, frontal setae; usually 2 orbital setae, posterior seta absent on one side in 4 and on both sides in 3 of 29 specimens examined by Norrbom (2002). Ocellar seta weak and small or minute. Antenna extended 0.70-0.85 distance to lower facial margin.

Dorsal head, thorax and abdomen, female.

Thorax: Mostly dark orange to dark red-brown with following areas yellow and distinctly contrasting: postpronotal lobe; single medial and paired sublateral vittae on scutum, the slender medial vitta extended nearly full length of scutum, broadened posteriorly, but extended laterally only slightly beyond level of acrostichal seta (at most half distance to level of dorsocentral seta); sublateral vitta extended from transverse suture to or almost to posterior margin, including intra-alar seta; scutellum except extreme base (brown area well separated from basal seta); propleuron; dorsal margin and anteroventral corner of anepisternum; greater ampulla and often bordering area of anepimeron; dorsal margin of katepisternum; katepimeron; and most of anatergite and katatergite. Mesonotal pattern with broad orange area bordering medial vitta, large orange sublateral presutural area, usually with narrow orange area of varying length bordering mesal margin of sublateral vitta. Darker areas of anepisternum and anepimeron mostly dark brown. Those of meron and katatergite dark orange or dark brown. Darker area of katepisternum orange. Subscutellum and mediotergite dark brown, narrowly orange medially. Mesonotum 3.41-3.74 mm long. Scutum microtrichose except for broad presutural bare area extended about midway to transverse suture; setulae mostly yellow. Katepisternal seta weak, shorter than postocellar seta, yellowish.

Wing: Length 7.24-8.15 mm. Vein M strongly curved apically; section between BM-Cu and R-M 2.51-2.75 times as long as section between R-M and DM-Cu; section between R-M and DM-Cu 0.69-0.76 times as long as DM-Cu. Crossvein DM-Cu oblique, with anterior end more distal than posterior end. Pattern mostly brown and pale to dark orange brown. C-band and S-band broadly connected in cell br and often in r2+3, but separated basally by hyaline area in posterior 2/3 of br aligned with pterostigma, usually a small basal hyaline area in cell dm, and hyaline to yellowish area covering all of cell bm. C-band with cell bc and posterior half to 2/3 of cell c yellowish to subhyaline, and large yellow area in base of cell sc and cells r1 and r2+3 posterior to pterostigma, gradually merging with orange brown distal part of band; margins of band, including most of pterostigma moderate brown. S-band largely yellow to orange in cell dm, darkening to orange brown anteriorly but middle section of band brown only narrowly on margins; distal section of band moderately broad, at apex of vein R2+3 0.51-0.64 times width of cell r2+3; separated from or extended to apex of vein M. Hyaline spot in cell r1 nearly triangular, extended well into cell r2+3, sometimes reaching vein R4+5; its apex aligned slightly basal to R-M. V-band with distal arm usually absent, rarely represented by faint spot in cell M (1m1f from Venezuela); proximal arm extended to vein R4+5, usually separated from S-band but occasionally narrowly connected along R4+5; extended basally along posterior wing margin often almost to vein A1+Cu2 but not connected to extension from base of S-band.

Wings.

Abdomen: Orange with yellow and brown markings. Syntergite 1+2 and tergite 3 each with brown band. Tergites 4-6 mostly orange. Posterior margin of tergites yellow, this area narrower laterally and also narrower on successive tergites, nearly absent on male tergite 5 and female tergite 6.

Male terminalia: Dorsal posterior margin of epandrium evenly convex. Lateral surstylus moderately long; in lateral view very slightly curved; in posterior view without strong basolateral lobe, main part narrowly triangular, acute apically. Proctiger with lateral fold separating sclerotized areas. Phallus 5.11-5.42 mm long; 1.50-1.53 times as long as mesonotum. Glans 0.40 mm long; acrophallus relatively stout.

Epandrium and surstyli, lateral and posterior.

Female terminalia: Oviscape 3.79-4.41 mm long, 1.07-1.21 times as long as mesonotum. Eversible membrane with 40-50 large, hook-like dorsobasal scales in triangular pattern. Aculeus 3.62-4.14 mm long; tip 0.23-0.28 mm long, 0.13-0.15 mm wide, gradually tapered and nonserrate. Spermathecae ovoid or teardrop shaped.

Aculeus tip, ventral.
