Oct 2024:  A recent paper using COI barcoding gene support concluded that Strombus alatus Gmelin, 1791 and Strombus  pugilis Linnaeus, 1758 were genetically the same, and the authors synonymized the two.  The result would be that S. alatus would then become a junior synonym to S. pugilis.  WoRMS and iNaturalist have recognized this change.  So, be sure to also see Strombus alatus.

Strombus pugilis is very similar to S. alatus Gmelin, 1791, the most common Stombidae found on both sides of the peninsula and the Florida Keys. S. pugilis is also reported as occurring in Florida. However, it has been suggested, and I would concur, that S. pugilis is not a native Floridian species, rather it is a Caribbean species that has reached the Florida peninsula and interbred with Florida's S. alatus. In my experience there is only one apparent location where the Caribbean S. pugilis and it's hybrids occur in Florida - Palm Beach County Florida’s east coast. In this area specimens can be found clearly having the characteristics of either S. alatus or the Caribbean S. pugilis as well as specimens with characteristics of both. The Caribbean S. pugilis specimens in this presentation are all from the Palm Beach area. S. alatus is treated in a separate presentation. A comparison of the two is presented in the last slide.
