Diagnosis. Anastrepha hyperacantha differs from most other species of Anastrepha by its pattern of dorsobasal denticles on the eversible membrane, with one medial denticle much larger than the others. In this regard it is similar to other species of the megacantha clade, but differs as indicated in the key.
In the key of Steyskal (1977) it runs to A. xanthochaeta Hendel , which differs in having orange setae and the aculeus tip slightly broader (0.065–0.090 mm, 1.07–1.23 times as long as wide vs. 0.12 mm, 1.82 times as long as wide in A. xanthochaeta ) and with the serrations only on the lateral margin (not extended onto the dorsal side as in A. xanthochaeta ), or A. similis Greene , which has a longer aculeus, vein R2+3 nonsinuous, and the apex of vein M less curved and not extended to the S-band. The aculeus tip also resembles that of A. sinvali Zucchi , which also differs in having orange setae, vein R2+3 nonsinuous, and vein M not extended to the S-band.
Description. Mostly yellow to orange. Setae red brown to black.
Head: Yellow to orange except brown ocellar tubercle. 3–4 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 1.5 times as long as ocellar tubercle. Facial carina, in profile, slightly 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, with following areas white (poorly differentiated in type specimens): postpronotal lobe and lateral margin of scutum bordering it; sublateral scutal vitta from transverse suture to posterior margin, including base of intra-alar seta; entire scutellum; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Medial scutal vitta not apparent. Subscutellum and mediotergite entirely orange. Mesonotum 3.32–3.53 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae mostly orange, laterally orange brown. Chaetotaxy typical for genus. Katepisternal seta weak, approximately one-third to half as long as anepisternal seta, but much weaker, orange to orange brown.
Legs: Entirely yellow to orange.
Wing ( Figs. 44–46 View FIGURES 38 – 49 ): Length 8.33–8.84 mm, width 3.60–3.75 mm, ratio 2.28–2.34. Apex of vein R1 at 0.63–0.65 wing length, aligned with or distal to level of anterior end of crossvein r–m. Cell c 0.86–0.90 times as long as pterostigma; pterostigma 5.42–6.00 times as long as wide. Vein R2+3 moderately to strongly sinuous. Crossvein r–m at 0.68–0.70 distance from bm–cu to dm–cu on vein M. Vein M very strongly curved apically; cell r4+5 0.68–0.89 times as wide at apex as at level of dm–cu. Cell bcu with distal lobe moderately long, length of bcu 1.52–1.63 times as long as anterior margin, lobe 0.68–0.89 times as long as vein A1+Cu2. Wing pattern mostly orange and moderate brown. C-band mostly orange, slightly paler at least posteromedially in cells bc and c, darker orange brown in pterostigma and with brownish streak in cell br. C-band and S-band narrowly connected to well separated along costa, broadly separated along veins R2+3 and R4+5 by hyaline band that extends from cell bm, slightly to strongly narrowed anteriorly in cell r1 and sometimes narrowly yellowish bordering costa. Basal hyaline area in cell dm relatively small. Basal half of S-band mostly orange, posterodistal margin brown, very broadly in cell cu1, without or with weak incision in cell cu1, proximal margin narrowly brown in radial cells; distal section orange brown and moderate brown, medium width to moderately broad, at apex of vein R2+3 0.49–0.63 times width of cell r2+3, extended to apex of vein M; hyaline area proximal to apex of band extending to vein R2+3 or very slightly into cell r1. V-band complete, mostly brown except proximal arm very narrowly orange bordering most of dm–cu and medially or in most of section in cell r4+5, proximal arm separated from S-band, on posterior margin extended at least three-fourths distance to vein A1+Cu2; distal arm connected to proximal arm; cell r4+5 with distinct hyaline area between V-band and vein M.
Abdomen: Mostly orange, without brown markings. Setulae orange brown.
Male terminalia ( Fig. 112, 113 View FIGURES 112 – 115. 112 – 113 ): Lateral surstylus relatively short, extended beyond prensisetae by 1.4–1.5 times length of prensiseta; in lateral view slightly posteriorly curved, rapidly tapering to relatively blunt apex; in posterior view broadly rounded, lateral and medial margins convex. Proctiger with ventral and lateral sclerotized areas connected but lateral areas separate dorsally. Phallus 3.9 mm long, 1.18 times as long as mesonotum; glans 0.60 mm long.
Female terminalia: Oviscape 2.42–2.67 mm long, 0.70–0.76 times as long as mesonotum, straight in lateral view, entirely orange or orange brown except basal half on ventral side; spiracle at basal 0.30–0.33. Eversible membrane ( Figs. 64–67 View FIGURES 64 – 70 ) with 1 very large medial hooklike denticle and 10–18 smaller hooklike dorsobasal denticles, no more than half as long as medial denticle, in 1–3 V-shaped rows in suboval pattern. Aculeus ( Figs. 82 View FIGURES 71 – 84 ) straight to very slightly ventrally curved in lateral view, 2.06–2.19 mm long, 0.85–0.87 times as long as oviscape, in ventral view base slightly expanded, 0.19–0.23 mm wide; shaft gradually tapered, 0.065–0.090 mm wide at midlength; tip ( Figs. 96 View FIGURES 94 – 99 ) 0.075–0.105 mm long, 0.04–0.05 times aculeus length, 0.065–0.090 mm wide, 1.07–1.23 times as long as wide, slightly tapered on basal half, apical 0.48–0.53 triangular and minutely serrate, 0.025–0.050 mm wide in lateral view, 0.36–0.56 times ventral width. Spermathecae elongate ovoid.

Etymology. This name is a noun in apposition, from the Greek “hyper”, meaning beyond or very, and “akantha”, meaning thorn, in reference to the much larger hooklike denticle on the eversible membrane.
