Anastrepha minensis Lima

Morphology

Thorax. Mesonotum length 2.33–3.25 mm (2.5, Zucchi 1978; 3.1, extensa holotype, Stone 1942). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Mesonotum yellow, or orange. Scutum with 3 (both medial and sublateral) pale postsutural vittae; pale sublateral postsutural vitta extended posteriorly to intra-alar seta. 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 6–8 mm (Lima 1937, Zucchi 1978; 7.25, extensa holotype, Stone 1942). 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; 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 (probable variation), or connected (narrowly 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 without 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; not connected anteriorly to S-band; not connected to S-band in cell dm. V-band distal arm complete, or incomplete, not reaching vein R4+5, but extended from vein M to wing margin; isolated, not connected to proximal arm of V-band or to S-band, or connected to proximal arm of V band. 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. 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. Glans present; without spinules. Oviscape entirely yellow to orange brown; straight; length 2.2–2.8 mm (2.5, extensa holotype, Stone 1942). Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Eversible membrane with with more than 100 denticles. Aculeus length 2–2.5 mm (Zucchi 1978; 2.28, extensa holotype, Stone 1942). Aculeus tip length/aculeus length 0.22–0.28 ("tip about one-fourth of total length", extensa holotype, Stone 1942). Aculeus tip length 0.4–0.55 mm (approx. 0.48 in Lima 1937, fig. 12); width 0.12–0.17 mm (0.13–0.16 in Lima 1937, fig. 12); not flared outward at or proximal to base; without ridges or lobes; with minute serration, visible only with compound microscope, or with fine serrations; serrated part 0.2–0.5 times length of tip (0.27–0.44 in Lima 1937, fig. 12, Stone 1942, fig. 21D). Aculeus tip serrations not extending onto dorsal side basally. Aculeus tip with serrations separated by less than width of serration.

Miscellaneous

Other names for this species: Anastrepha extensa Stone. Data source: Lima 1937, Zucchi 1978, Stone 1942 (extensa holotype). Sex of recorded specimens: male and female. Species group: fraterculus group.

Biology and economic significance

This species has been reported from several economically important fruits, but the reliability of these records is uncertain and its economic significance is uncertain. Refer to the Fruit Fly Databases for host plant information.
