Etymology: The name of this species is an adjective that means very sharping (from the Latin acuminis) in reference to the shape of the aculeus tip. Recognition. In the key of Korytkowski (2004) A. acuminata runs to page 97, alternative 153, to A. duckei Lima or A. irretita Stone. The new species differ from A. duckei in the aculeus tip ratio, four times as long as wide in A. duckei and 1.94–2.71 times in A.acuminata . The serrate part is near a half of the aculeus tip in A. irretita and 7/ 8 in the new species. This species is most similar to A. caudata Stone in the size and shape of the aculeus. Anastrepha acuminata differs from A. caudata because it has more hooks on the eversible membrane ( Fig 2 .A), by its shorter aculeus, by the lack of ocellar setae and because the wing pattern is mostly yellow in the new species and the hyaline area in cell br is extended to vein R4+5, the pattern is mostly brown in A. caudata and the hyaline area in cell br is narrow, not extended to vein R4+5. Description. Mostly yellow. Setae dark brown to black; setulae yellowish. Head : 1.13 mm long, 1.48– 1.69 mm high, 1.44–1.77 mm wide. Yellow except ocellar tubercle black. Face flat, not microtrichose. Facial carina, in profile, concave. 3–4 frontal setae (3 on right side, 4 on left). Antenna 0.34 mm long, 0.14 mm wide in frontal view. Arista pubescent, 0.81 mm long. 2 orbital setae well developed. Ocellar setae absent. Thorax : Mostly yellow, microtrichose. Scutal vittae white; medial scutal vitta slender, broadened and rounded posteriorly. Mesonotum 2.69–2.87 mm long, 1.94–2.23 mm wide. Katepisternal seta long and slender (as long as orbital setae but more slender). Subscutellum and mediotergite yellow. Wing (Fig 1. A): 6.91–7.61 mm long, 2.91–4.46 mm wide. Cell c 1.16–1.33 times as long as pterostigma. Apex of vein R1 at 0.43–0.53 wing length. Apex of vein M moderately curved, ending approximately midway between apices of S and V-bands; cell r4+5 0.64–0.81 times as wide at apex as at level of DM-Cu. Crossvein R-M at 0.66–0.68 length of cell dm. Pattern mostly yellow, most margins of bands, most of pterostigma, distal part of S-band and posterior parts of V-band brown. S and C-bands narrowly joined along R4+5. V-band complete and separated from S-band, apex faint. Microtrichose, except the alula and cells bc, c, bm and hyaline part in the base of dm. Abdomen : Tergites entirely yellow. Female terminalia : Oviscape 2.86–3.03 mm long, 1.0–1.12 times as long as mesonotum. Spiracle at basal 0.89–1.03 mm , at 0.31–0.34 length of oviscape. Eversible membrane ( Fig 2 . A, B) with approximately 60 strong, slender hook-like dorsobasal scales in triangular pattern. Aculeus 2.97–3.07 mm long, 0.1–0.16 mm wide at the end of oviduct. Aculeus tip tapering ( Fig 3 . A–C), 0.31–0.38 mm long, 1.94–2.71 times as long as wide, 0.06 mm depth at the end of oviduct, serrated on distal 7/8, with a slight constriction before serrate part. In the paratype teeth of the aculeus tip hardly visible in 40x , but easily visible in holotype ( Figs 3 . A, B). Serrate part 0.28–0.30 mm long, 0.10–0.12 mm wide, 2.5–2.8 times as long as wide. Comments. The aculeus of this species resembles the species of the caudata group ( Norrbom & Caraballo 2003 ), however other apomorphic characters are different. The wing pattern is yellow and the hyaline area in cell br is extended to vein R4+5, distal hyaline area in cell dm is not narrowed and the oviscape is entirely yellow, thus A. acuminata does not belong to this group. Based in aculeus tip shape, particularly the size of serrate part and the slight constriction before it, A. acuminata belongs to fraterculus group. The holotype and paratype differ in the size of the teeth on the aculeus tip, but as other characters, including the absence of the ocellar setae and their body size are similar, it does not seem reasonable to consider these specimens to be different species.
