Anastrepha paradentata Norrbom 1985: 124 [nomen nudum; wing, aculeus tip]; Korytkowski 1997: 47 [nomen nudum; in key], 2004: 22 [nomen nudum; in list].

Diagnosis. Anastrepha paradentata differs from other species of Anastrepha except A. phaeoptera Lima and A. trivittata , n. sp., by the color pattern of its scutellum, which has only the sides brown on the basal third. Species of the daciformis group have both the disc and the sides of the scutellum darker basally, and a few other Anastrepha species have the disc dark basally, but not the sides. Anastrepha paradentata differs from A. phaeoptera in having pale orange brown rather than dark brown wing bands, with the C-band and S-band separated, and from A. trivittata in having a marginal hyaline area distal to the apex of vein R1 and lacking brown abdominal markings. The eversible membrane, with the dorsobasal scales all small and weak, the extremely slender aculeus, the short lateral surstylus, and the lack of a glans are all typical of the dentata group. Within that group, only A. dentata (Stone) has similar posterior scutal marks, but it differs from A. paradentata in having an entirely yellow scutellum, orange to red brown setae, and shorter female terminalia (oviscape 2.27–2.52 mm long, aculeus 1.85–1.90 mm long). In the key of Steyskal (1977b: 15), A. paradentata runs poorly to A. insulae Stone which has a broader aculeus, eversible membrane with large hooklike scales, and the distal arm of the V-band well developed. It might be confused with species of the punctata group which also have a pair of dark spots on the scutum posteriorly, but those species also lack scutellar brown markings and have eversible membranes with larger scales.

Description. Mostly orange to orange brown, with white to pale yellow markings. Setae dark red brown to black.

Head: Yellow to orange except brown ocellar tubercle. 3–5 frontal setae (fifth seta small if present); 2 orbital setae, posterior seta well developed. Ocellar seta weak, at most 1.5 times as long as ocellar tubercle. Facial carina, in profile, straight dorsally and medially. Antenna extended 0.78–0.87 distance to ventral facial margin.

Thorax ( Figs. 5–6 ): Mostly orange to orange brown with following areas white to pale yellow: postpronotal lobe and lateral margin of scutum bordering it, extending to presutural supra-alar seta, poorly differentiated on notopleuron; medial scutal vitta, slender except posterior sixth broadly and abruptly expanded, extended laterally almost to dorsocentral seta, subquadrate or somewhat bilobed, indented posteriorly by orange or brown area extended to or almost to acrostichal seta; paired, very slender, dorsocentral scutal vitta, sometimes interrupted or diffuse posteriorly; paired sublateral scutal vitta from transverse suture to posterior margin, including base of intraalar seta; scutellum except narrow basal margin of disc and basal third or more of side; dorsal margins of anepisternum and katepisternum; katepimeron; and most of anatergite and katatergite. Posterior margin of scutum with paired, triangular or wedge-shaped dark brown mark, extending anteriorly to or slightly beyond dorsocentral seta, at most halfway to transverse suture; sometimes connected by dark brown along scuto-scutellar suture or latter sometimes with medial brown spot; lateral brown mark often with short, narrow lateral lobe along margin of white intra-alar vitta. Scutellum with basal third to half of side dark brown, extending beyond basal seta. Subscutellum and mediotergite entirely orange to orange brown or diffusely dark brown laterally. Mesonotum 3.60–3.93 mm long. Postpronotal lobe, scutum, and scutellum entirely microtrichose; scutal setulae yellow to orange medially, brownish laterally. Chaetotaxy typical for genus. Katepisternal seta undifferentiated or weak, at most half as long as largest anepisternal seta, but much weaker.

Legs: Entirely yellow to orange.

Wing ( Fig. 12 ): Length 8.80–9.42 mm, width 3.30–3.70 mm, ratio 2.55–2.75. Apex of vein R1 at 0.57–0.61 wing length. Cell c 1.06–1.15 times as long as pterostigma; pterostigma 4.50–5.83 times as long as wide. Vein R2+3 without sharp bends or undulations. Crossvein r-m at 0.68–0.73 distance from bm-cu to dm-cu on vein M. Vein M moderately strongly curved apically; cell r4+5 0.82–0.95 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.43–1.62 times as long as anterior margin. Wing pattern mostly yellowish and orange brown. C-band mostly yellowish to orange, fainter in cells bc and c, and darker orange brown in pterostigma. C-band and S-band separated, sometimes more narrowly along vein R4+5; hyaline area in cell br large and elongate, reaching vein R4+5 and 3–5 times as long as distal colored area of cell; cell dm with basal hyaline area moderately large. Basal half of S-band relatively narrow, mostly yellowish to orange, posterior margin moderate brown, broadly in cell cu1 narrowing in cell dm, anterior margin sometimes narrowly brown in cell dm; distal section orange to orange brown, medium width, at apex of vein R2+3 0.56–0.63 times width of cell r2+3, slightly broadening or even in width, well separated from apex of vein M; hyaline area proximal to apex of band ending at vein R2+3 or occasionally extended slightly into cell r1. V-band incomplete; proximal arm slender, moderate brown posterior to vein M, narrowly connected to or narrowly separated from S-band along vein R4+5, on posterior margin with proximal extension at least halfway to vein A1+Cu2, but often fainter proximally; distal arm absent or occasionally reduced to marginal spot in cell m.

Abdomen: Mostly orange, without brown markings.

Male terminalia: Lateral surstylus very short and blunt, extended beyond prensisetae by less than length of prensiseta; in posterior view with epandrium nearly oval in shape. Proctiger with ventral and lateral sclerotized areas connected but lateral areas separate dorsally. Phallus 0.75 mm long, 0.20 times as long as mesonotum; glans absent.

Female terminalia: Oviscape 3.30–3.65 mm long, 0.89–0.96 times as long as mesonotum, straight in lateral view, entirely orange brown; spiracle at basal 0.25–0.28. Eversible membrane with all dorsobasal scales small and weak. Aculeus straight or slightly ventrally curved in lateral view, 2.47–2.67 mm long, 0.71–0.75 times oviscape length; in ventral view base strongly expanded, 0.15 mm wide; shaft 0.025–0.030 mm wide at midlength; tip ( Fig. 33 ) with base difficult to distinguish (i.e., length of tip difficult to measure), 0.15–0.17 mm long, 0.06–0.07 times aculeus length, 0.025–0.030 mm wide, 5.3–6.2 times as long as wide, 0.025 mm wide in lateral view, 0.83–1.00 times ventral width, in ventral view weakly sagittate, expanded part 0.05 mm long, nonserrate but with slightly irregular margin. Spermathecae not examined.

Distribution. Anastrepha paradentata is known only from western Mexico.

Biology. The host plants and other aspects of the biology of this species other than dates of capture of adults are unknown. The larvae probably feed inside seeds of species of Sapotaceae as in other species of the dentata group for which host plants are known.

Etymology. The name of this species is an adjective derived from the Greek para, meaning near, and dentata , the name of a closely related species.

Comments. This name was used in a doctoral dissertation and several manuscript keys used in training courses, but none of these are available for purposes of zoological nomenclature.
