Abstract

Crangonyx hobbsiShoemaker, 1941, a variable stygobitic amphipod endemic to the Floridan aquifer, is redescribed from topotype material and populations adjacent to the type locality. In addition to the morphological redescription, genetic sequence data for sections of the nuclear 18S rDNA, 28S rDNA, and mitochondrial 16S rDNA are provided from populations located near the type locality.
