Diagnosis. Anastrepha peneramosa differs from other species of Anastrepha except A. ramosa Stone and A. subramosa Stone in having the aculeus tip with exceptionally large serrations. It also resembles those species in wing pattern and other characters, except the medial spot on the scuto-scutellar suture is small or absent. It also differs from A. ramosa and A. subramosa in the shape of the aculeus tip, having a weak constriction basal to the serrate part. It further differs from A. ramosa in having shorter terminalia (oviscape 2.76–3.17 mm long vs. 6.45–6.9 mm in A. ramosa) and in that the gap between the basal and subbasal serrations is not elongate as in A. ramosa. It further differs from A. subramosa in aculeus tip width (0.10 mm vs. 0.18–0.21 mm) and the length to width ratio of the tip (1.30 vs. 0.83–0.94).
Description. Mostly yellow to orange, with white to pale yellow markings. Setae dark red brown to black. Head: Yellow to orange; ocellar tubercle brown; gena, except anteroventral margin and narrowly bordering eye, reddish brown. 4–5 frontal setae; 2 orbital setae, posterior seta well developed. Ocellar seta weak, 1.2 times as long as ocellar tubercle. Facial carina, in profile, straight or slightly convex on dorsal two-thirds. Antenna extended 0.78–0.82 distance to ventral facial margin. Palpus in lateral view dorsally curved, evenly setulose.
Thorax: Mostly yellow to orange, without brown markings except small brown spot sometimes present medially bordering scuto-scutellar suture; with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it; very slender medial scutal vitta, ovoid posteriorly and extended laterally to or slightly beyond acrostichal seta; 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. Subscutellum and mediotergite entirely orange. Mesonotum 3.53–3.63 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae yellowish to brownish. Chaetotaxy typical for genus. Katepisternal seta poorly differentiated from setulae, at most half as long as anepisternal seta, weak, orange.
Legs: Entirely yellow to orange.
Wing (Fig. 36): Length 7.98–8.08 mm, width 3.22–3.29 mm, ratio 2.43–2.51. Apex of vein R1 at 0.55–0.56 wing length, proximal to level of anterior end of crossvein r–m. Cell c 1.19–1.46 times as long as pterostigma; pterostigma 3.15–3.54 times as long as wide. Vein R2+3 not sinuous. Crossvein r–m at 0.63–0.67 distance from bm–cu to dm–cu on vein M. Vein M moderately curved apically; cell r4+5 0.93–0.98 times as wide at apex as at level of dm–cu. Cell bcu with distal lobe moderately long, length of bcu 1.52–1.58 times as long as anterior margin, lobe 0.68–0.77 times as long as vein A1+Cu2. Wing pattern mostly orange and moderate brown. C-band mostly orange; moderate brown in most of pterostigma; distal margin in cells r1 and r2+3 narrowly brown. C-band and S-band broadly connected along vein R4+5; hyaline marginal spot in cell r1 triangular, with apex proximal to crossvein r–m. 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 cell br; distal section orange except brown apically in cell r4+5 and on posterior margin in cell r2+3, relatively broad, at apex of vein R2+3 0.65–0.70 times width of cell r2+3, not 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; proximal arm brown posteriorly, orange bordering most of dm–cu and broadly in cell r4+5, connected to S-band anteriorly, on posterior margin extended half to three-fifths distance to vein A1+Cu2; distal arm connected to proximal arm.
Abdomen: Mostly orange, without brown markings. Setulae orange, brown on posterior and lateral margins.
Female terminalia: Oviscape 2.76–3.17 mm long, 0.78–0.87 times as long as mesonotum, straight in lateral view; entirely orange; spiracle at basal 0.27–0.32. Eversible membrane (Fig. 56) with 30–35 slender, hooklike dorsobasal denticles in 3–4 irregular rows in subtriangular pattern. Aculeus (Fig. 77) ventrally curved in lateral view, 2.76 mm long, 0.87 times oviscape length; in ventral view base gradually expanded, 0.24 mm wide; shaft 0.09 mm wide at midlength; tip (Fig. 91) 0.13 mm long, 0.05 times aculeus length, 0.10 mm wide, 1.30 times as long as wide, 0.07 mm wide in lateral view, 0.70 times ventral width; in ventral view strongly expanded basally, elongate triangular, lateral margin with 3–4 extremely large and several smaller serrations, serrate part 1.31 times as long as tip. Spermathecae not examined.
Distribution. Anastrepha peneramosa is known only from eastern Perú.
Biology. The host plants and other aspects of the biology of this species are unknown.
Type data. Holotype Ƥ (SENASA USNMENT 00671977), PERÚ: Madre de Dios: Tahuamanu, Shiringayoc, McPhail trap 2,1,1,1, 19 Oct 2007, N. Nolazco 0296-07. Paratype: PERÚ: Madre de Dios: Tahuamanu, Shiringayoc, 2008, N. Nolazco, 028-08, 1Ƥ (USNM USNMENT 00671129).
Etymology. The name of this species is an adjective from the Latin “pene” (almost, near) and “ ramosa ”, the epithet of one of the most closely related species.
Comments. This species belongs to the ramosa group in which all three species have a sagittate aculeus tip with extremely large serrations.
