Observations on the life histories of Paramacroderoides pseudoechinus sp. n. (Digenea: Plagiorchioidea) and P. echinus Venard 1941, trematodes from the Florida gar.
Paramacroderoides pseudoechinus sp. n. is described from the intestine of Lepisosteus platyrhincus. Life history studies reveal that developmental stages previously reported for P. echinus from gars belong instead to the new species. The account of the life history of P. echinus is emended accordingly and differences in structure and behavior between that species and P. pseudoechinus are described.
