New species and records of Anastrepha (Diptera: Tephritidae) from Brazil Author Norrbom, Allen L. Author Uchôa, Manoel A. text Zootaxa 2011 2835 61 67 journal article 10.5281/zenodo.277361 fb763d71-ef6a-4b27-b5f2-25d7c7a39da6 1175-5326 277361 Anastrepha oiapoquensis Norrbom & Uchôa , new species Figs. 2 , 8, 9 Diagnosis. In the key of Zucchi (2000a) A. oiapoquensis runs to A. barbiellinii Lima or A. minensis Lima and in that of Steyskal (1977) it runs to A. barbiellinii . It differs from both species in the shape of the aculeus tip, which does not taper gradually, the more extensive serrations of the tip (distal 0.41 serrate, vs. less than distal 0.3 in A. barbiellinii and A. minensis ), and having vein M weakly curved apically. It also somewhat resembles A. vermespinata Tigrero , but differs in having shorter terminalia and in the shape of the aculeus tip (serrate part broader than long in A. vermespinata ). The large number of hook-like dorsobasal scales on the eversible membrane and the relatively distal position of crossvein r-m are also useful diagnostic characters. FIGURES 6–12. Female terminalia: 6–7, A. matogrossensis (holotype), aculeus and tip, ventral; 8–9, A. oiapoquensis (holotype), aculeus and tip, ventral; 10–12, A. siculigera (holotype), aculeus, lateral and ventral, and tip, ventral. Description. Mostly orange, white to pale yellow markings not well developed in holotype . Setae mostly lost, orange brown. Head: Orange except brown ocellar tubercle. Setae mostly lost; 2–3 alveoli for frontal setae; 2 alveoli for orbital setae, posterior seta apparently well developed. Ocellar seta weak, as long as ocellar tubercle. Facial carina, in profile, straight dorsally and medially. Antennae lost. Thorax: Mostly orange, without brown markings, typical white to pale yellow areas not well differentiated in holotype except postpronotal lobe and scutellum. Subscutellum and mediotergite entirely orange. Mesonotum 2.06 mm long. Postpronotal lobe and scutellum entirely microtrichose; scutum microtrichose medially and laterally, nonmicrotrichose from slightly lateral to acrostichal line to intra-alar line; scutal setulae orange. Chaetotaxy typical for genus. Katepisternal seta weak, only twice as long as katepisternal setulae. Legs: Entirely yellow to orange. Wing ( Fig. 2 ): Length 5.50 mm , width 2.26 mm , ratio 2.43. Apex of vein R1 at 0.59 wing length. Cell c 1.13 times as long as pterostigma; pterostigma 4.08 times as long as wide. Vein R2+3 not sinuous. Crossvein r-m at 0.70 distance from bm-cu to dm-cu on vein M. Vein M weakly curved apically; cell r4+5 1.15 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe relatively short, length of bcu 1.27 times as long as anterior margin. Wing pattern orange and moderate brown. C-band mostly orange; most of pterostigma and narrow distal margin of band in cells r1, r2+3 and br brown. C-band and S-band narrowly connected along vein R4+5, marginal hyaline area distal to apex of vein R1 subtriangular, extended to vein R4+5, its apex aligned proximal to crossvein r-m. Hyaline area in cell br large and elongate, reaching vein R4+5 and ca. 2 times as long as distal colored area of cell; cell dm with basal hyaline area large. S-band with margins, except proximal margin in cell dm, mostly narrowly brown, and posterodistal two-thirds of band in cell cu1 brown; posterior margin without incision in cell cu1; distal section of band moderately broad, at apex of vein R2+3 0.62 times width of cell r2+3, even in width, well separated from apex of vein M, mostly brown, most of central part orange in cells r1 and r2+3; hyaline area proximal to apex of band extending almost to vein R2+3. V-band complete, brown except most of proximal arm in cell r4+5; proximal arm separated from S-band, with basal extension along wing margin extending more than two-thirds distance to vein A1+Cu2; distal arm moderately broad, connected to proximal arm and extending to vein R4+5. Abdomen: Mostly orange, without brown markings. Female terminalia: Oviscape 2.36 mm long, 1.15 times as long as mesonotum, straight in lateral view, entirely orange; spiracle at basal 0.34. Eversible membrane with ca. 90 long, slender, hook-like dorsobasal scales. Aculeus slightly ventrally curved in lateral view, 2.24 mm long, 0.95 times oviscape length; in ventral view ( Fig. 8 ) base slightly expanded, 0.21 mm wide; shaft parallel-sided, 0.15 mm wide at midlength; tip ( Fig. 9 ) 0.29 mm long, 0.13 times aculeus length, 0.15 mm wide, 1.93 times as long as wide, 0.06 mm wide in lateral view, 0.40 times ventral width, in ventral view slightly tapered, then almost parallel-sided, distal 0.41 triangular and minutely serrate. Spermathecae not examined. Distribution. Anastrepha oiapoquensis is known only from Brazil (Amapá). Biology. The host plants and other aspects of the biology of this species other than date of capture of the holotype are unknown. Type data. Holotype female ( UFGD USNMENT 00671879), BRAZIL : Amapá: Municipio Oiapoque, Clevelândia do Norte, 30°49'35"N 51°51'39"W , McPhail trap, 23 Nov 2002 , R. B. R. Trinadade & M. A. Uchôa. Etymology. The name of this species is derived from the municipality of the type locality.
