Anastrepha pulchra is one of three species of the serpentina group with the C- and S-bands broadly fused so that there is no hyaline area in the middle of cell br. It differs from the other two species, A. pulchella Norrbom and A. anomoiae Norrbom, in having a triangular brown mark on the orbital plate, and narrower, more elongate, yellow medial areas on the posterior margins of abdominal tergites 3 and 4, and in the male, cells bm and dm entirely infuscated. The aculeus tip is 0.33-0.46 long (shorter than in A. anomoiae, longer than in A. pulchella), and entirely nonserrate. The marginal hyaline spot in cell r1 is elongated along the costa, and its apex is aligned with or distal to crossvein R-M; it is aligned with R-M in A. anomoiae and proximal to it in A. pulchella. See Recognition for A. pulchella and A. anomoiae for additional differences.
Classification and Evolutionary Relationships
Order: Diptera. Family: Tephritidae. Genus: Anastrepha. Species: pulchra. Author: Stone.
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 pulchra has been placed in the serpentina species group. Norrbom (2002) analyzed the relationships among the species of the serpentina group (see Phylogeny of the Anastrepha serpentina group) and considered Anastrepha pulchra to be most closely related to A. anomoiae Norrbom.

The biology of A. pulchra is poorly known. The only reported host plant is an undetermined species of Sapotaceae (Caraballo 1981).
Anastrepha pulchra is not considered a pest species.
The wing illustration in Stone (1942, Pl. 2C) is of A. pulchella. The two males from Venezuela examined by Norrbom (2002) have the section of vein M between R-M and DM-Cu short, but the females are within the range of the other specimens for this character. The aculeus tip of the single Venezuelan female dissected has the tip slightly less tapered basally than in other females. The Brazilian female has the longest aculeus tip, although it is among the shortest in oviscape and aculeus length.
