Anastrepha panamensis Greene

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 2.75–4 mm (2.83–3.76, n=12; 3.0–3.9, Stone 1942). Postpronotal lobe and notopleuron mostly or entirely nonmicrotrichose. Scutum nonmicrotrichose (except postsutural margin lateral to postsutural supra-alar seta). Scutellum disc mostly or entirely without microtrichia. 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. Mesonotum yellow, or orange. Scutum with 3 (both medial and sublateral) pale postsutural vittae; pale medial vitta with posterior end ovoid, or with posterior end broadly quadrate; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. Scutum posteriorly without brown or orange brown markings, or with only single medial brown spot on scuto-scutellar suture. Scutum without brown vittae. Scutellum entirely yellow or with dark markings only on extreme base of disk. Mesopleuron mostly yellow to orange, without brown markings. Subscutellum entirely yellow to orange. Mediotergite entirely yellow to orange. Femora entirely yellow to orange. Fore femur with posterodorsal and ventral rows of well developed setae.

Wings. Wing length 6.2–8 mm (6.28–7.93, n=10). 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 connected (along vein R4+5, cell r1 with basomarginal hyaline spot). Basal hyaline area between C-band and S-band extended to vein R4+5. Cell r1 basomarginal hyaline spot triangular to quadrate. Cell r1 basomarginal hyaline spot apex aligned proximal to crossvein r-m. 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 posterior margin with distinct incision in cell cu1. 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 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, or extending less than 1/3 distance from apex of vein Cu1 to apex of vein A1+Cu2; not connected anteriorly to S-band; not connected to S-band in cell dm. V-band distal arm complete; connected to proximal arm of V band. Apex of V-band not extended from vein R4+5 to vein M, hyaline area present between band and vein M. 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. Vein R2+3 not sinuous; without accessory vein. Vein R4+5 distal to crossvein r-m more or less evenly curved or not strongly bowed medially. Vein M ratio (distance from bm-cu to r-m/distance from bm-cu to dm-cu) 0.61–0.67 (0.63–0.65, n=3). 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. Abdomen ovate or parallel-sided, syntergite 1+2 gradually broadening or parallel-sided. Abdominal tergite without brown markings. Lateral surstylus in posterior view not boot-shaped. Phallus length 4.5–5.75 mm (4.64–5.67, n=5); ratio (phallus length/mesonotum length) 1.35–1.7 (1.40–1.64, n=5). Glans present; without spinules. Oviscape entirely yellow to orange brown, or at least apex brown; straight; length 3.2–4.4 mm (3.24–3.86, n=7; 4.33 in Colombian female, Canal 2010); length ratio (oviscape length/mesonotum length) 1–1.15 (1.01–1.14, n=7); spiracle ratio (distance from base to spiracle/oviscape length) 0.15–0.25 (0.19–0.22, n=2; 0.21 in Colombian female, Canal 2010); spiracle ratio to mesonotum length (distance from base to spiracle/mesonotum length) 0.2–0.25 (0.22–0.23, n=2). Eversible membrane with dorsobasal denticles with gap of membranous or no denticles separating apical row(s) from smaller basal denticles. Aculeus length 2.65–3.35 mm (2.73–3.24, n=6; 3.15 in Colombian female, Canal 2010). Aculeus in ventral view more or less parallel-sided except extreme base. Aculeus in lateral view straight or ventrally curved. Aculeus tip length 0.04–0.09 mm (0.065–0.080, n=5; 0.04 in Colombian female, Canal 2010); lateral margins not curved dorsally; 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: Stone 1942; data with sample numbers new. Sex of recorded specimens: male and female. Species group: panamensis group.

Biology and economic significance

This species may be a minor or potential pest of species of Chrysophyllum (Sapotaceae). Its only reported hosts are two species of that genus. Refer to the Fruit Fly Databases for host plant information.
