Diagnosis. Anastrepha wittiensis   can be distinguished from other species of Anastrepha   by the following combination of characters: Scutum with brown band on posterior margin; subscutellum entirely orange; C-band posterior to pterostigma mostly orange; C-band and S-band broadly connected, hyaline area between them extended to vein R 4+5; V-band complete, connected to S-band; oviscape 2.02–2.31 mm long, 0.60 times as long as mesonotum; aculeus strongly dorsally curved, 1.48 mm long; tip 0.22 mm long, 0.15 times aculeus length, distal 0.25 very finely serrate. It is most similar to other species of the robusta   group, especially A. amaryllis Tigrero   , A. crassaculeus   , A. furcata   Lima, A. fuscata Norrbom & Korytkowski   , and A. robusta Stone   , in which the aculeus is also strongly dorsally curved. It differs from all of these species in having the aculeus tip finely serrate. It differs further from A. amaryllis   in having the distal part of the S-band narrower and shorter terminalia (oviscape more than 3 mm long in A. amaryllis   ), from A. crassaculeus   in lacking an extension on the S-band in cell m 4, having vein M 1 more strongly curved apically, fewer dorsobasal denticles on the eversible membrane, the aculeus not broadest at midlength, and the tip longer, from A. furcata   and A. fuscata   in having the orange area of the C-band extending broadly into cells r 1 and r 2+3, and from A. robusta   in having a slightly more elongate aculeus tip (3.26 times as long as wide in A. wittiensis   vs. 2.44–2.89 times in A. robusta   ).

In the key of Zucchi et al. (2011) A. wittiensis   runs to A. montei   Lima, from which it differs in having a brown band on the posterior margin of the scutum, the aculeus dorsally curved and less rapidly tapered, and the aculeus tip longer and broader. Sequences for A. wittiensis   were not included in the COI analysis of Moore et al. (in prep.).

Description. Mostly orange. Setae dark red brown.

Head: Mostly yellow to orange, except ocellar tubercle brown. 3–5 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, 1.2–1.5 times as long as ocellar tubercle. Facial carina, in profile, straight or concave on dorsal two-thirds. Antenna not extended to ventral facial margin. Palpus in lateral view dorsally curved, evenly setulose.

Thorax: Mostly yellow to orange, most of scutum orange; with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it; medial scutal vitta, broadly quadrate posteriorly, extending laterally to dorsocentral seta; sublateral scutal vitta from transverse suture to posterior margin, including base of intraalar seta; scutellum except extreme base; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Scutum with brown band on posterior margin, not extended laterally to intra-alar seta. Subscutellum and mediotergite entirely orange. Mesonotum 3.39–3.85 mm long. Postpronotal lobe, notopleuron, scutum and scutellum entirely microtrichose; scutal setulae orange, pale brown laterally, evenly distributed sublaterally. Chaetotaxy typical for genus. Katepisternal seta weak, orange, less than half length of anepisternal seta.

Legs: Entirely yellow to orange.

Wing ( Figs. 72–73 View FIGURES 67–73 ): Length 7.06–8.18 mm, width 2.78–3.19 mm, ratio 2.54–2.55. Apex of vein R 1 at 0.53–0.54 wing length, proximal to level of anterior end of crossvein r-m. Cell c 1.27–1.35 times as long as pterostigma; pterostigma 3.69–4.10 times as long as wide. Vein R 2+3 not sinuous. Crossvein r-m at 0.65–0.68 distance from bm-m to dm-m on vein M 1. Vein M 1 very strongly curved apically; cell r 4+5 at apex 0.73–0.86 times as wide as at level of dm-m, 0.59–0.65 times as wide as maximum subapical width. Cell cu a with distal lobe moderately long, length of cu a 1.57–1.62 times as long as anterior margin, lobe 0.68–0.70 times as long as vein CuA+CuP. Wing pattern mostly orange and moderate to dark brown. C-band mostly orange, base of cell c slightly darker, pterostigma mostly dark brown, distal margin of band in cells r 1 and r 2+3 narrowly brown, base and fork of vein Rs brown and small irregular brown marks aligned with it in extreme base of cell r 2+3 and in cell br, cell br also with triangular brown mark on distal margin of band. C-band and S-band broadly connected along vein R 4+5; hyaline marginal spot in cell r 1 subtriangular, with apex aligned proximal to anterior end of crossvein r-m. Basal hyaline area in cell dm relatively large. Basal half of S-band moderately broad, mostly orange, anterobasal margin narrowly brown in cells br, r 1, r 2+3, posterodistal margin narrowly brown anteriorly, more broadly posteriorly in cell m 4, extending into lobe of cell cu a, with strong incision in cell m 4; distal section mostly brown, with central orange area in cells r 1 and r 2+3; moderately broad, at apex of vein R 2+3 0.65–0.77 times width of cell r 2+3, extended to or almost to apex of vein M 1, without marginal hyaline areas; hyaline area proximal to apex of band extended to vein R 2+3. V-band with proximal arm moderately broad, mostly brown, orange medially in cell r 4+5 and bordering anterior part of crossvein dm-m; broadly connected to S-band along vein R 4+5; on posterior margin extended approximately two-thirds distance to vein CuA+CuP; distal arm mostly to entirely brown, connected to proximal arm; with or without hyaline area between arms of V-band and vein M 1, if present less than one-third width of cell cell r 4+5.

Abdomen: Mostly orange, without brown markings.

Female terminalia: Oviscape 2.02–2.31 mm long, 0.60 times as long as mesonotum; entirely orange; spiracle at basal 0.38–0.41. Eversible membrane ( Fig. 97 View FIGURES 92–97 ) with 7–8 hooklike dorsobasal denticles in irregular distal row in addition to approximately 13 short, stout, triangular denticles in suboval pattern. Aculeus ( Figs. 119–129 View FIGURES 98–120 View FIGURES 121–131 ) in lateral view strongly dorsally curved, 1.48 mm long, 0.73 times oviscape length; in ventral view base distinctly expanded, triangular, 0.18 mm wide, shaft 0.06 mm wide at midlength; tip ( Fig. 144 View FIGURES 132–144 ) 0.22 mm long, 0.15 times aculeus length, 0.068 mm wide, 3.26 times as long as wide; in ventral view rapidly tapered, then parallel-sided, distal 0.25 very finely serrate, bluntly roundeed; 0.07 mm wide in lateral view, 1.04 times ventral width. Spermathecae not examined.

Etymology. The name of this species is derived from Witti Creek, where part of the type series was collected.

Comments. This species belongs to the robusta   species group as indicated by the dark posterior band on the scutum, the connected wing bands, and the dorsally curved aculeus. It was not included in a preliminary phylogenetic analysis using anchored hybrid enrichment (Wiegmann et al., in prep.) nor the COI analysis of Moore et al. (in prep.).
