First record of the species complex in the American Gulf of Mexico Coastline, as confirmed by morphological and molecular approaches.

isopods exhibit a constrained morphology that makes identification difficult. In the Greater Caribbean, a convoluted taxonomic history has left the distributional limits of unclear. To date, no confirmed records of this species exist from the American Gulf of Mexico. Herein, we report the presence of in Sarasota-Manatee Florida, as confirmed by morphological and molecular approaches. This is the first record of this species in the region and a ~300Km extension of its range. Specimens were collected in mangroves, underscoring the importance of protecting these habitats.
