Diagnosis. In the key of Steyskal (1977) A. pseudacris runs to page 21, but it differs from A. acris Stone in lacking a medial scutal vitta, having the S-band and V-band separated, seta color (black vs. orange brown to dark red brown) and the aculeus tip less serrate (distal 0.71–0.77 vs. 0.83–0.95). Anastrepha pseudacris is also similar to A. acuminata Canal , but differs in having shorter terminalia (oviscape length 2.4–2.81 mm vs. 2.86–3.03 mm in A. acuminata , oviscape/mesonotum length 0.86–0.97 vs. 1.00– 1.20 in A. acuminata , aculeus length 2.30–2.70 mm vs. 2.97–3.07 mm in A. acuminata ), fewer dorsobasal denticles on the eversible membrane (25–30 vs. approximately 60 in A. acuminata ), a shorter aculeus tip (0.28–0.30 mm vs. 0.31–0.38 mm in A. acuminata ), larger serrations on the aculeus tip, and lacking a medial scutal vitta.

Description. Mostly yellow to orange. Setae dark.

Head: Yellow to orange except brown ocellar tubercle. 3–4 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta absent. Facial carina, in profile, slightly concave. Antenna not extended to ventral facial margin. Palpus in lateral view dorsally curved, with sparse setulae.

Thorax ( Fig. 4 ): Mostly yellow to orange, without brown markings; with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; scutellum; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite; medial vitta possibly absent. Subscutellum and mediotergite entirely pale yellow to orange. Mesonotum 2.50–2.80 mm long. Postpronotal lobe, notopleuron, scutum and scutellum entirely microtrichose; scutal setulae yellow to orange. Chaetotaxy typical for genus. Katepisternal seta usually weak, yellowish, at most 0.55 times length of anepisternal seta.

Legs: Entirely yellow to orange.

Wing ( Fig. 9 ): Length 6.90–7.40 mm, width 2.94–3.20 mm, ratio 2.33–2.40. Apex of vein R 1 at 0.52–0.57 wing length, proximal to level of anterior end of crossvein r-m. Cell c 1.19–1.37 times as long as pterostigma; pterostigma 3.36–3.59 times as long as wide. Vein R 2+3 not sinuous. Crossvein r-m at 0.66–0.71 distance from bm-m to dm-m on vein M 1. Vein M 1 moderately curved apically; cell r 4+5 0.80–0.89 times as wide at apex as at level of dm-m. Cell cu a with distal lobe relatively short, length of cu a 1.39–1.51 times as long as anterior margin, lobe 0.51–0.56 times as long as vein CuA+CuP. Wing pattern mostly orange and moderate brown. C-band mostly orange, without hyaline area in cell c, distal margin in cells r 1 and r 2+3 narrowly brown, pterostigma mostly moderate brown. C-band and S-band connected along vein R 4+5; hyaline marginal spot in cell r 1 triangular to subquadrate, with apex aligned proximal to crossvein r-m. Basal hyaline area in cell dm small. Basal half of S-band mostly orange, posterodistal margin partly to mostly narrowly brown, more broadly in cell m 4 but much narrower than orange area, almost reaching apex of lobe of cell cu a, without incision in cell m 4; distal section narrowly brown on most of margins, relatively broad, at apex of vein R 2+3 0.66–0.81 times width of cell r 2+3, not extended 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 relatively narrow, mostly orange, margins in cell dm narrowly brown, and entire part in cell m 4 brown; separated from S-band along vein R 4+5; distal arm slender, brown except anteriorly, broadly connected to proximal arm, hyaline area between band and vein M 1 relatively large.

Abdomen: Mostly orange, without brown markings.

Female terminalia ( Figs. 21 , 25 , 34 ): Oviscape 2.40–2.81 mm long, 0.86–0.97 times as long as mesonotum, straight in lateral view; entirely orange; spiracle at basal 0.27–0.31. Eversible membrane ( Fig. 21 ) with dorsobasal denticles in subtriangular pattern, with 25–30 relatively short hooklike denticles in 4–5 V-shaped rows. Aculeus ( Fig. 25 ) straight in lateral view, 2.30–2.70 mm long, 0.96–0.98 times oviscape length; in ventral view base distinctly expanded, 0.23–0.24 mm wide, shaft 0.12–0.13 mm wide at midlength; tip ( Fig. 34 ) 0.28–0.30 mm long, 0.10–0.12 times aculeus length, 0.14–0.15 mm wide, 2.00–2.14 times as long as wide; in ventral view slightly narrowed basally, distal 0.71–0.77 triangular, with relatively large serrations, lateral margin of triangular part straight; 0.04 mm wide in lateral view, 0.26–0.28 times ventral width. Spermathecae not examined.
