Concept Reference
Cannizzaro, A. G., D. Balding, E. A. Lazo-Wasem, and T. R. Sawicki. 2019. Morphological and molecular analyses reveal a new species of stygobitic amphipod in the genus Crangonyx (Crustacea: Crangonyctidae) from Jackson County, Florida, with a redescription of Crangonyx floridanus and notes on its taxonomy and biogeography. Journal of Natural History 53(7-8):1-49.
Taxonomic Comments
This is the narrow concept of Crangonyx floridanus as redescribed by Cannizzaro et al. (2019). Specimens from Gerard's Cave, Jackson County, Florida, used in the original description of Crangonyx floridanus, are now assigned to C. manubrium.
