Anastrepha atlantica Uramoto & Zucchi

Morphology

Body. Setae dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–6 (usually 4). Orbital setae 2. Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face without brown markings. Arista of male without preapical expansion.

Thorax. Mesonotum length 2.8–3.8 mm (2.9–3.7). Postpronotal lobe and notopleuron entirely microtrichose. Scutum mostly or entirely microtrichose. Scutellum disc entirely microtrichose. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Mesonotum yellow, or orange. Scutum presutural dorsocentral pale vitta absent; with 2 (sublateral) pale postsutural vittae; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings, or with only single medial brown spot on scuto-scutellar suture (usually). Scutum without brown vittae. Scutellum entirely yellow or with dark markings only on extreme base of disk. Mesopleuron mostly yellow to orange, without brown markings. Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange.

Wings. Wing length 7–9 mm (7.45–8.6). Wing pattern typical Anastrepha pattern (S-band complete or at most interrupted at crossvein r-m, C-band and at least proximal arm of V-band present). Cell c mostly or entirely infuscated to subhyaline, or paler posteriorly, without distinct subapical hyaline area. C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3; yellow or orange area posterior to pterostigma broad, extending distally into cells r1 and r2+3 at least to level of midlength of pterostigma. C-band and S-band connected (broadly in females, narrowly in males along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended to vein R4+5. Cell r1 basomarginal hyaline spot triangular to quadrate. Cell r1 basomarginal hyaline spot apex aligned proximal to crossvein r-m. S-band extended anteriorly to vein R4+5 and covering all of crossvein r-m. Cell bm entirely hyaline or infuscated only along subapical fold. S-band posterior margin with distinct incision in cell cu1. S-band base without extension in middle of cell cu1 to posterior wing margin; without extension in cell a1 to or almost to posterior margin. S-band middle section predominantly or entirely orange, often with brown margins. Subapical hyaline area in radial cells distal to r-m extending anteriorly to vein R2+3. S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. S-band distally not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band; extending more than 1/3 distance from apex of vein Cu1 to apex of vein A1+Cu2; connected anteriorly to S-band along vein R4+5 or in cell r2+3; not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band. Apex of V-band extended from vein R4+5 to vein M, no hyaline area present between band and vein M. Area surrounding apex of lobe of cell bcu with large oval area of very dense microtrichia. Vein R2+3 not sinuous; without accessory vein. Vein R4+5 distal to crossvein r-m more or less evenly curved or not strongly bowed medially. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.63–0.72 (0.64–0.71). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 1.05–1.2 (1.09–1.17). Costa in male with setulae on anterior margin between crossvein h and apex of vein R1 similar to other setulae. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. Abdominal tergites evenly microtrichose. Epandrium posterodorsal margin evenly rounded. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view long, inner side concave, outer side convex. Phallus length 4.1–4.9 mm (4.4–4.6); ratio (phallus length/mesonotum length) 1.2–1.6 (1.3–1.5). Glans present; without spinules. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape length 2.8–3.8 mm; ratio (oviscape length/mesonotum length) 0.85–1.2 (0.90–1.14). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with 35–45 denticles (long, hooklike dorsobasal scales). Aculeus length 2.7–3.5 mm (2.75–3.43). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus tip length 0.05–0.09 mm (0.06–0.08); width 0.09–0.11 mm (0.10); length/width in ventral view 0.5–0.9 (0.6–0.8); lateral margins not curved dorsally; parallel-sided, then triangular; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; with medium sized serrations, or with large serrations; serrated part 0.6–0.8 times length of tip (0.66–0.78). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration. Egg without lobe.
