Diagnosis. This species can be recognized by the following combination of characters: extremely short aculeus tip (less than 0.1 mm long), well defined, apical 0.66–0.78 evidently serrate; aculeus 2.75–3.43 mm long; all wing bands connected; vertex of the V-band broad and extending to vein M; posterior margin of Sband with distinct triangular incision in cell cu1; scuto-scutellar suture with medial dark brown spot. In the key of Zucchi (2000), A. atlantica runs to mixta or amnis, from which differs in having the aculeus tip very short (0.06–0.08 mm long).
Description. Mostly yellow to pale brown. Setae black.
Head: Pale brown, except blackish ocellar tubercle. Facial carina, in profile, concave. 3–6 (usually 4) frontal setae; 2 orbital setae well developed, posterior seta slightly more slender than anterior one; ocellar setae brown, minute, weak.
Thorax: Integument mostly yellow to orange with following areas white: postpronotal lobe; paired sublateral scutal vitta from transverse suture to posterior margin; and entire scutellum. A medial dark brown spot on the scuto-scutellar suture (sometimes weakly defined in females and present or absent in males). Subscutellum and mediotergite entirely orange. Mesonotum 2.9–3.7 mm long. Scutum entirely microtrichose, including postpronotal lobe and scutellum. Setae black (Fig. 3c). Katepisternal seta small, weak and pale brown.
Wing (Fig. 3a–b): Length 7.45–8.6 mm, width 3.27–3.78 mm. Crossvein DM-Cu 1.2–1.45 mm long. Section of vein M between BM-Cu and R-M 1.8–2.4 times as long as section between R-M and DM-Cu. Section between R-M and DM-Cu 0.6–0.9 times as long as DM-Cu. Veins dark brown. Vein M slightly curved apically; cell r4+5 1.09–1.17 times as wide at apex as at level of DM-Cu. Pattern mostly orange and moderate brown. Pterostigma moderate brown. Posterior margin of S-band with distinct triangular incision in cell cu1. C-band, S-band and V-band broadly connected along vein R4+ 5 in females, but narrowly in males; apex of Vband elongate, extended across cell r4+5, from R4+5 to M.
Abdomen: Pale brown. Tergites without markings, entirely microtrichose; setulae pale brown.
Female terminalia (Fig. 3d–e): Oviscape 2.8–3.8 mm long, 0.90–1.14 times as long as mesonotum, entirely microtrichose; spiracle at basal 0.9–1.1 mm. Eversible membrane with about 40 hooklike denticles in triangular pattern. Aculeus 2.75–3.43 mm long; in ventral view base expanded, 0.2 mm wide; shaft 0.12 mm wide at midlength, sides parallel; tip short, 0.06–0.08 mm long, 0.1 mm wide, 1.25–1.67 times as wide as long; basal part slightly narrowing, apical 0.66–0.78 evidently serrate, broadly triangular, abruptly tapered to rounded apex. Spermathecae ovoid, about 0.1 mm wide (broadest diameter), sclerotized, with outer surface covered by V-shaped spines (Fig. 3f). Egg white, slightly curved, 2.2 mm long in straight line, posterior third very slender (Fig. 3g).
Male terminalia (Fig. 4a–c): Dorsal posterior margin of epandrium evenly convex. Lateral surstylus moderately long, extended beyond prensisetae insertion by ca. 3.5 times length of prensiseta; in lateral view curved; in posterior view broad on basal half, gradually tapered to blunt apex; lateral margin convex, medial margin slightly convex then straight to slightly concave. Proctiger with lateral fold separating sclerotized areas but ventral and lateral sclerotized areas narrowly connected. Distiphallus 4.4–4.6 mm long, 1.3–1.5 times as long as mesonotum. Glans 0.50–0.52 mm long.
Discussion. This species differs from most other Anastrepha, above all by the length of the aculeus tip (less than 0.1 mm). There are a few other species with short aculeus tip, but in this case, shape and width differ from A. atlantica. Tip aculeus short is found in the dentata group, although it is poorly defined in the species of this group. Furthermore, apart from the aculeus very narrow, the dorsobasal teeth of the eversible membrane are small and weak in dentata group (Norrbom et al. 1999).
Wing pattern similar to A. atlantica occurs in various species of the robusta group (Norrbom & Korytkowski 2009) as well as other Anastrepha species, e.g., A. benjamini Lima, as this species also has the area of dense microtrichia around the lobe on cell bcu and vein A1+Cu2 (Norrbom 1997), however, in none of these species the vertex of the V-band is so broad, i.e., extending to vein M. Anyway, A. atlantica does not show any other character, as listed by Norrbom & Korytkowski (2009) for the robusta group.
The sclerotized areas of the proctiger are connected, which excludes this species from the grandis - fraterculus set of species groups (Norrbom et al. 1999). The male genitalia is similar to A. benjamini, as described by Norrbom (1977), however A. atlantica differs by its shorter aedeagus Thus, through present knowledge, it is not possible to classify this new species into any of the known species groups of Anastrepha.
Therefore, the shape of the aculeus tip and the wing pattern (all bands connected, broad vertex of the Vband and triangular incision on posterior margin of S-band) distinguish A. atlantica from other species of Anastrepha.
Distribution. Known only from locality-type in Espírito Santo state, Brazil.
Host. Unknown.
Comments. The males were associated with females in this species based on wing pattern and similar size.

Etymology. The name of this species is a Latin adjective referring to rain forest where type material was collected.
