The genus Pseudoniphargus comprises a number of stygobiont Amphipoda, distributed on both sides of the Atlantic. In Bermuda, groundwaters are inhabited by two species. P. grandimanus and P. carpalis , both new. They occur throughout the entire salinity spectrum, from infrahalne to euhaline, but are most abundant in oligohaline waters. Large adults, but no ovigerous specimens. arc found at greater distance from the sea coast than juveniles, which may indicate that Pseudoniphargus needs anchihaline/marine waters for its reproduction and that juveniles migrate inland to grow up.
