Anastrepha zucchii belongs to the daciformis species group, which differs from other species of Anastrepha in having the basal third of the scutellum brown, the male phallus extremely short (less than 0.30 mm long) and with the glans absent (as in the dentata group), and the female eversible membrane dorsobasally with a single, medially interrupted row of very stout scales. Anastrepha zucchii is one of several species with a vespidlike wing pattern comprising only a broad, uninterrupted, costal band covering all of cell r2+3, and a cubital streak. It differs from other species of the macrura complex (aquila, avispa, bicolor and macrura) as follows: Notopleuron entirely dark, and presutural lateral pale stripe reduced to a spot anterolateral to presutural supra-alar seta that is isolated from pale area on postpronotal lobe; presutural dorsocentral pale stripe absent; wing with broad, moderate brown stripe from cell bcu to apex of cell cu1, not extended into cell dm; V-band completely absent, crossvein dm-cu without faint brown border; and dorsal brown mark on frons usually bilobed and narrowest medially. It further differs from A. macrura as follows: pale medial stripe on abdomen not expanded on apical half of syntergite 1+2, sometimes connected to transverse band on base of syntergite 1+2; tergites without narrow white lateral margins; occiput dark except anterior margin; and facial carina entirely yellow.
Classification and Evolutionary Relationships
Order: Diptera. Family: Tephritidae. Genus: Anastrepha. Species: zucchii. Author: Norrbom.
Relationships among the species of Anastrepha were analyzed by Norrbom et al. (1999) and McPheron et al. (1999). Click here for more detailed discussion of Anastrepha phylogeny. Anastrepha zucchii has been placed in the daciformis species group. Norrbom (1998) analyzed the relationships among the species of the daciformis group (see Phylogeny of the Anastrepha daciformis group) and included A. zucchii in the macrura complex, which also includes A. aquila Norrbom, avispa Norrbom, bicolor (Stone), and macrura Hendel, of which A. macrura appears to be most closely related to A. zucchii.

The biology of Anastrepha zucchii is poorly known. Its host plants are unknown, although it probably attacks fruits of species of Sapotaceae like other species of the daciformis species group.
Anastrepha zucchii is not considered a pest species.
This species was named for Roberto A. Zucchi, in recognition of his contributions to Anastrepha systematics.
