Anastrepha anomala Stone

Recognition
Anastrepha anomala 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. Of the other species with this character, A. anomala is most likely to be confused with A. normalis and A. pseudanomala. It differs from both species by its more slender, tapered aculeus tip (no more than 0.12 mm wide), and at least from A. normalis in having a strong basolateral lobe on the lateral surstylus (the male is unknown for A. pseudanomala). It further differs from A. normalis in having the middle section of the S-band solidly dark brown anterior and distal to crossvein R-M, and the aculeus tip finely serrate on the distal half or more (except in Maranhão, Brazil female). Most females have slightly longer terminalia (oviscape more than 1.4 times mesonotum length; aculeus more than 4.3 mm long) than in A. normalis and A. pseudanomala, but they are shorter in a single female from Bahia, Brazil (see Comments).

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; 1-2 orbital setae, posterior seta well developed if present. Ocellar seta weak, short to minute. Antenna extended 0.75-0.90 distance to lower facial margin.

Thorax: Mostly 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 less than half distance from acrostichal seta to dorsocentral seta; sublateral vitta extended from transverse suture 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; dorsal margin of katepisternum; katepimeron; and most of anatergite and katatergite. Mesonotal pattern similar to A. normalis; broad area bordering medial vitta, shorter and narrower area bordering mesal margin of sublateral vitta, and large sublateral presutural area orange. Darker areas of anepisternum and katepisternum orange; those of anepimeron, meron, and katatergite mostly dark brown. Subscutellum and mediotergite dark brown, narrowly dark orange medially. Mesonotum 3.06-3.66 mm long. Scutum microtrichose except for broad presutural bare area extended about 3/4 distance to transverse suture; setulae mostly yellow, brown on parts of darker areas. Katepisternal seta weak, slightly to much shorter than postocellar seta, yellowish to red-brown.

Wing: Length 6.67-7.90 mm. Vein M strongly curved apically; section between BM-Cu and R-M 2.04-2.62 times as long as section between R-M and DM-Cu; section between R-M and DM-Cu 0.74-0.85 times as long as DM-Cu (0.69 times in Bahia female). Crossvein DM-Cu oblique, with anterior end more distal than posterior end. Pattern mostly dark brown. C-band and S-band broadly connected in cells r2+3 and br, but separated basally by hyaline area in posterior half of br aligned with pterostigma, hyaline basal sixth of cell dm, and hyaline to yellowish area covering all of cell bm. C-band yellowish to subhyaline in cell bc and posterior half to 2/3 of cell c; with large yellowish area in base of cell sc and cells r1 and r2+3 posterior to pterostigma, extending distally to or almost to level of apex of vein R1. S-band with large yellow area in cell dm usually extending into cell br and sometimes nearly touching crossvein R-M; rest of band dark brown, including areas distal to and anterior to R-M; distal section moderately broad, at apex of vein R2+3 0.33-0.61 times width of cell r2+3 (0.49-0.61 times in Panamania specimens; 0.45 times in Maranhão, Brazil female; in Bahia female, slender at apex of R2+3, 0.33-0.38 times width of cell r2+3, but slightly broader along vein R4+5); not extended to apex of vein M. Hyaline spot in cell r1 nearly triangular, extended well into cell r2+3 and sometimes to vein R4+5; its apex aligned with R-M or usually slightly basal to it. V-band with distal arm absent; proximal arm separated from S-band, extended to vein R4+5; extended basally along posterior wing margin 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 tergites 3-4 each with band, brown laterally, orange medially, on tergite 4 often entirely orange; posterior margin yellow, narrowing laterally and on successive tergites. Tergite 5 and female tergite 6 orange.

Male terminalia: Dorsal posterior margin of epandrium evenly convex. Lateral surstylus moderately long; in lateral view slightly curved; in posterior view, with strong basolateral lobe, main part narrowly triangular, acute apically. Proctiger with lateral fold separating sclerotized areas. Phallus 6.2-7.1 mm long; 1.94-2.04 times as long as mesonotum. Glans 0.50-0.55 mm long; acrophallus relatively stout.

Epandrium and surstyli, lateral and posterior.

Female terminalia: Oviscape 4.49-5.58 mm long, 1.44-1.56 times as long as mesonotum (3.70 mm, 1.02 times mesonotum length in Bahia female). Eversible membrane with 35-40 large, hook-like dorsobasal scales in triangular pattern. Aculeus 3.62-5.51 mm long (4.37-5.12 mm in Panamanian females; 5.51 mm in Maranhão female; 3.62 mm in Bahia female); tip 0.19-0.32 mm long, 0.09-0.12 mm wide (0.27-0.32 mm long, 0.105-0.12 mm wide in Panamanian females; 0.24 mm long, 0.10 mm wide in Bahia female; 0.19 mm long, 0.09 mm wide in Maranhão female), gradually tapered, very finely serrate on apical 0.60-0.67 in Panamanian females, on apical 0.50 in Bahia female, nonserrate in Maranhão female. Spermathecae ovoid.

Aculeus tip, ventral, A. anomala: Panama; Brazil, Bahia; Brazil, Maranhao.

Egg (based on a sample of five dissected from the abdomen of a female from Arraijan, Panama (USNM00052951)): Similar in shape to A. serpentina, posterior end elongate and tapered. Anterior end without lobe (i.e., micropyle at apex). Length 1.75-1.82 mm, broadest width 0.20-0.22 mm.
