Diagnosis. In the key of Uramoto & Zucchi (1999) to the species of the punctata species group Anastrepha coronis runs to A. punctata Hendel or A. morvasi Uramoto & Zucchi. It also resembles A. quadripuncta Troya & Norrbom. It can be distinguished from A. punctata by its broader and serrate aculeus tip, seta color (orange to orange brown vs pale yellow to pale orange), connected S- and V-bands, and lack of brown markings on the abdominal tergites. It differs from A. morvasi in having fewer dorsobasal denticles on the eversible membrane, a longer aculeus (1.05–1.28 mm long vs. 0.79–0.86 mm in A. morvasi ), and a shorter and more serrate aculeus tip (0.04–0.05 vs. 0.085 –0.095 mm; serrate part/tip length ratio 1.06–1.50 vs. 0.89–0.90 in A. morvasi ). It differs from A. quadripuncta in having paler setae, the scutellum without a brown lateral mark between the basal and apical setae, shorter terminalia (oviscape 1.54–1.62 mm long, 0.51–0.59 times as long as mesonotum vs. 2.83–2.85 mm, 0.95–1.00 in A. quadripuncta ), and shorter, narrower and more serrate aculeus tip.

Description. Mostly yellow to orange. Setae orange to orange brown.

Head: Yellow to orange except brown ocellar tubercle. 3–4 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 2 times longer than ocellar tubercle. Facial carina, in profile, slightly concave. Antenna not extended to ventral facial margin. Palpus in lateral view dorsally curved, evenly setulose.

Thorax ( Fig. 3 ): Mostly yellow to orange, scutum posteriorly with a pair of brown spots between dorsocentral and intra-alar lines; scuto-scutellar suture with or without medial transverse ovoid brown spot; 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 scutal vitta indistinct or absent. Subscutellum and mediotergite entirely pale yellow to orange. Mesonotum 2.70–3.01 mm long. Postpronotal lobe, notopleuron, scutum and scutellum apically entirely microtrichose; scutal setulae orange to orange brown. Chaetotaxy typical for genus. Katepisternal seta weak, yellowish, at most 0.62 times length of anepisternal seta, usually less than half as long.

Legs: Entirely yellow to orange.

Wing ( Fig. 8 ): Length 7.21–7.59 mm, width 2.81–3.2 mm, ratio 2.34–2.57. Apex of vein R 1 at 0.54–0.59 wing length, proximal to level of anterior end of crossvein r-m. Cell c 0.96–1.15 times as long as pterostigma; pterostigma 4.19–5.00 times as long as wide. Vein R 2+3 slightly sinuous. Crossvein r-m at 0.67–0.69 distance from bm-m to dm-m on vein M 1. Vein M 1 relatively weakly curved apically; cell r 4+5 0.92–1.09 times as wide at apex as at level of dm-m. Cell cu a with distal lobe relatively large, length of cu a 1.35–1.54 times as long as anterior margin, lobe 0.70–0.89 times as long as vein CuA+CuP. Wing pattern mostly pale orange and pale brown. C-band mostly pale orange, cell c diffusely subhyaline subapically and posteriorly, pterostigma mostly moderate brown, distal margin in cells br, r 1 and r 2+3 narrowly pale brown; node of vein Rs with small dark brown spot. C-band and S-band broadly separated, hyaline area between them sometimes narrowed along vein R 2+3; basal hyaline area in cell dm relatively small, triangular. Basal half of S-band broad, mostly pale orange, posterodistal margin partly to mostly pale brown, more broadly in cell m 4 but brown area much narrower than orange part and not reaching apex of cell cu a, with or without weak incision in cell m 4; distal section narrowly brown on most of margins, broad at apex of vein R 2+3, with or without very narrow marginal hyaline band in cell r 2+3, not extended to apex of vein M 1; hyaline area proximal to apex of band extended to vein R 2+3. V-band with proximal arm relatively narrow, pale brown posteriorly, pale orange area bordering most of dm-m in cells dm and m 1 and in mostly or entirely in cell r 4+5; narrowly connected to S-band in cell r 2+3; distal arm slender, pale brown except anteriorly, near connected to proximal arm; hyaline area between arms of V band and vein M 1 relatively large, more than half width of cell r 4+5.

Abdomen: Mostly orange, without brown markings.

Male terminalia ( Figs. 45–46 ): Epandrium in lateral view shorter than high. Lateral surstylus in posterior view short and narrow posterolaterally projected, extended beyond prensisetae by 2.6–3.3 times length of prensiseta; in lateral view relatively short, apex broad and blunt and posteriorly curved. Proctiger with lateral and ventral sclerotized areas separated. Phallus 2.00– 2.20 mm long, 0.66–0.77 times as long as mesonotum; glans 0.40–0.45 mm long.

Female terminalia ( Figs. 20 , 24 , 33 ): Oviscape 1.54–1.62 mm long, 0.51–0.59 times as long as mesonotum, straight in lateral view; entirely orange; spiracle at basal 0.31–0.37. Eversible membrane ( Fig. 20 ) with dorsobasal denticles in semi-ovoid pattern, with 15–20 relatively short and slender hooklike denticles in 4–5 irregular rows. Aculeus ( Fig. 24 ) straight in lateral view, 1.05–1.28 mm long, 0.65–0.78 times oviscape length; in ventral view base distinctly but gradually expanded, 0.16–0.19 mm wide, shaft 0.07–0.08 mm wide at midlength; tip ( Fig. 33 ) 0.04–0.05 mm long, 0.03–0.04 times aculeus length, 0.07 mm wide, 0.57–0.71 times as long as wide; in ventral view distal 0.05–0.06 mm gradually tapered, lateral margin convex, apically blunt, with very fine blunt serrations, serrated part 1.06–1.5 times length of tip; 0.02 mm wide in lateral view, 0.28 times ventral width. Spermathecae not examined.

Etymology. The name of this species is an adjective derived from the Latin coronam, meaning corona, in reference to the shape of the aculeus tip.

Comments. This species is placed in the morvasi species group, which also includes A. morvasi from southeastern and southern Brazil, and A. quadripuncta from Ecuador ( Troya et al. 2020), based on the following combination of characters: setae orange brown; scutum with pair of posterior brown marks; subscutellum without brown marks; C-band and S-band separated along vein R 4+5; S-band often with marginal hyaline marks; hyaline area present between V-band and vein M 1; vein M 1 weakly curved apically; and aculeus tip partially serrate.
