Anastrepha urichi Greene

Morphology

Body. Setae orange, or orange brown.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. 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 3.8–4.5 mm (4.02–4.27, n=4). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Mesonotum yellow, or orange, or dark orange. 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.

Wings. Wing length 9–10.2 mm (9.37–9.79, n=4). 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). C-band broadly extending to vein M in cell br along cell bm; covering base of cell r2+3. C-band and S-band connected (broadly along vein R4+5, cell r1 with basomarginal hyaline spot). 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 infuscated. 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 distally not extended to apex of vein M. V-band proximal arm as dark as apical half of S-band; connected anteriorly to S-band along vein R4+5 or in cell r2+3. 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 (0.705, n=1). Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdominal tergite without brown markings. 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. Phallus length 0.8–1.4 mm (1.1, n=1); ratio (phallus length/mesonotum length) 0.2–0.32 (0.264, n=1). Glans absent. Oviscape length 4.6–5.2 mm (4.85–5.00, n=2); ratio (oviscape length/mesonotum length) 1.1–1.3 (1.17–1.21, n=2); spiracle ratio (distance from base to spiracle/oviscape length) 0.28–0.34 (0.31, n=1). Eversible membrane with dorsobasal denticles all small, weakly developed, in triangular to semicircular pattern. Aculeus length 3.8–4.4 mm (4.02–4.25, n=2, latter measurement according to Stone 1939 for holotype). Aculeus tip width 0.025–0.035 mm (0.029, Stone 1939); lateral margins not curved dorsally; without ridges or lobes; without elongate dorsolateral depressions apically; with minute serration, visible only with compound microscope, or with fine serrations.

Miscellaneous

Data source: Stone 1939. 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.
