This species is closely similar to Strombus pugilis, the West Indian fighting conch, which has a more southerly range. S. alatus shells have less prominent subsutural spines and slightly more projected outer lips. Some scientists have treated the two as distinct species; others as subspecies. In an extensive study of the Stromboidea in 2005, Simone provisionally treated these as distinct species, but observed, "no spectacular morphological difference was found [and] all related differences, even those of the genital system, can be regarded as extreme of variation of a single, wide distributed, variable species."
A cladogram based on sequences of nuclear histone H3 gene and mitochondrial cytochrome-c oxidase I (COI) gene showing phylogenetic relationships of (32 analyzed) species in the genus Strombus and Lambis, including S. alatus, was proposed by Latiolais et al. (2006):

The minimum recorded depth for this species is the surface; the maximum recorded depth is 183 m.
