This species 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 castanea is one of three species with a wing pattern comprising only a narrow, uninterrupted, costal band (not covering all of cell r₂₊₃), a distinct band covering crossvein DM-Cu, and a cubital streak not extended along vein Cu₁ beyond BM-Cu.  It is most similar to A. daciformis and A. katiyari, but differs in having the lateral presutural pale stripe interrupted and absent from the scutum (i.e., pale area on postpronotal lobe not connected to pale area on posterior half of notopleuron), and in having the white markings of the abdomen reduced, with no apical band or spot on tergite 4. The female terminalia are longer than in A. daciformis, but shorter than in A. katiyari (see Table).

Classification and Evolutionary Relationships
Order: Diptera. Family: Tephritidae. Genus: Anastrepha. Species: castanea. 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 castanea 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. castanea in the daciformis complex along with A. daciformis Bezzi and katiyari Norrbom.

Biology
The biology of Anastrepha castanea 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.

Economic Significance
Anastrepha castanea is not considered a pest species.

Comments
The name of this species refers to its largely redbrown coloration.
