Anastrepha paradentata Norrbom & Korytkowski

Morphology

Body. Setae dark red brown, or dark brown to black.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Frontal setae 3–5. 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 with ventral part gradually tapered laterally; without brown markings. Antenna not extended to ventral margin of face.

Thorax. Mesonotum length 3.4–4.1 mm (3.60–3.93, n=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; postpronotal seta on posterior half of postpronotal lobe. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Katepisternal seta moderately developed, larger than postocellar seta, but much smaller and weaker than anepimeral seta, or weak, no larger than postocellar seta. Mesonotum orange, or dark orange; with short presutural lateral pale vitta on lateral margin of scutum, not extended onto notopleuron, or with presutural lateral pale vitta on lateral margin of scutum, extended to posterior notopleural seta, or with presutural lateral pale vitta on lateral margin of scutum and posterior part of notopleuron (including posterior corner) (present but often poorly differentiated on notopleuron). Scutum presutural dorsocentral pale vitta absent (or poorly differentiated), or present and connected anteriorly with pale area of postpronotal lobe; with 3 (both medial and sublateral) pale postsutural vittae, or with 5 (medial, dorsocentral, and sublateral) pale postsutural vittae; pale medial vitta with posterior end broadly quadrate, or with posterior end bilobed; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly with pair of brown spots or markings, or with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum posteriorly with pair of triangular brown marks on or near dorsocentral line (sometimes also with medial spot on scuto-scutellar suture or marks connected along posterior margin to form shallow U-shaped mark); with irregular brown markings; scutal posterior brown band not extended laterally to include intra-alar seta; without brown vittae, or with dark brown dorsocentral vitta (short if present, at most extending midway from posterior margin to transverse suture). Scutellum brown on side, markings not connected apically (basal third to half of side broadly dark brown). Mesopleuron mostly yellow to orange, without brown markings. Subscutellum entirely yellow to orange, or yellow to red brown medially, dark brown laterally (brown area diffuse if present). Mediotergite entirely yellow to orange, or yellow to red brown medially, dark brown laterally (brown area diffuse if present). Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wings. Wing length 8.6–9.6 mm (8.80–9.42, n=7). 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 separated (by hyaline band from cell bm to costal margin in cell r1, sometimes narrower along vein R4+5). 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 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 into cell r1 (occasionally), or 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; not connected anteriorly to S-band (narrowly), or connected anteriorly to S-band along vein R4+5 or in cell r2+3 (narrowly); not connected to S-band in cell dm. V-band distal arm present only in cell m (as marginal spot), or absent; isolated, not connected to proximal arm of V-band or to S-band. S-band distal section width ratio (width of S-band/width of cell r2+3, both measured perpendicular to costal margin at apex of vein R2+3) 0.5–0.7 (0.56–0.63, n=5). Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. Area between S-band and V-band entirely microtrichose in cells dm and cu1. Cell c: pterostigma ratio (cell c length/pterostigma length) 1–1.2 (1.06–1.15, n=6). Pterostigma ratio 4.50–5.83, n=6. Vein R1 ratio (distance from wing base to apex of R1/wing length) 0.57–0.61, n=6. Vein R2+3 not sinuous; without accessory vein. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.67–0.74 (0.68–0.73, n=6). Vein M curvature ratio (width of cell r4+5 at apex/width at level of dm-cu) 0.75–1 (0.82–0.95, n=6). Cell bcu ratio (length/anterior margin length along vein Cu) 1.4–1.67 (1.43–1.62, n=6). 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. Epandrium in lateral view shorter than high. Lateral surstylus in posterior view without basolateral lobe. Lateral surstylus in posterior view very short, barely extended beyond prensisetae, rounded apically. Lateral surstylus in posterior view not boot-shaped. Lateral surstylus in lateral view short, apex blunt. Phallus length 0.5–1 mm (0.75, n=1); ratio (phallus length/mesonotum length) 0.1–0.3 (0.20, n=1). Glans absent. Proctiger lateral and ventral sclerotized areas connected, lateral areas separate dorsally. Oviscape entirely yellow to orange brown; straight; length 3.2–3.75 mm (3.30–3.65, n=5); length ratio (oviscape length/mesonotum length) 0.85–1 (0.89–0.96, n=5); spiracle ratio (distance from base to spiracle/oviscape length) 0.23–0.3 (0.25–0.28, n=5). Eversible membrane with dorsobasal denticles all small, weakly developed, in triangular to semicircular pattern. Aculeus length 2.3–2.85 mm (2.47–2.67, n=5). Aculeus length/oviscape length 0.65–0.8 (0.71–0.75, n=5). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length/aculeus length 0.04–0.08 (0.061–0.065, n=3). Aculeus tip length 0.13–0.19 mm (0.155–0.166, n=3; difficult to measure, proximal limit of tip difficult to distinguish); width 0.02–0.04 mm (0.025–0.030, n=2); length/width in ventral view 5–6.5 (5.3–6.2, n=2); depth (width in lateral view)/width (in ventral view) 0.75–1.1 (0.83–1.00, n=2); lateral margins not curved dorsally; slender, with extreme apex sagittate; not flared outward at or proximal to base; without ridges or lobes; without elongate dorsolateral depressions apically; not serrate; serrated part 0 times length of tip.

Miscellaneous

Data source: Norrbom & Korytkowski 2010. Sex of recorded specimens: male and female. Species group: dentata group.

Biology and economic significance

This species is not considered economically important. Its host plants are unknown, although it probably attacks fruits of species of Sapotaceae like other species of the dentata species group. Refer to the Fruit Fly Databases for host plant information.
