This species belongs to the daciformis species group, which differs from most other species of Anastrepha in having the basal third or more 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 antilliensis differs from all other species of the daciformis group as follows: scutum with medial pale stripe rounded posteriorly, and sublateral pale stripe not extended to intra-alar seta. Other useful diagnostic characters include: the posterior orbital seta, usually absent in other species of the group, usually present; C- and S-bands separated; S-band complete, basally with broad extension across vein Cu₂+A₁ to posterior wing margin; and scutum mostly yellow, with 2 dark brown lateral spots, one anterior to and one posterolateral to postsutural supra-alar seta, and with large, irregular dark brown area on posterior margin.

Classification and Evolutionary Relationships
Order: Diptera. Family: Tephritidae. Genus: Anastrepha. Species: antilliensis. 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 antilliensis 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).  The postion of A. antilliensis is unresolved, but it appears to be either the basalmost species of the clade or to belong to a clade that also includes A. murrayi, maculata, and stonei, that is the sister group of the rest of the daciformis group.

Biology
The biology of Anastrepha antilliensis 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 antilliensis is not considered a pest species.

Comments
The species name refers to its known distribution, two islands of the Greater Antilles.
