Microcharon quilli, a new asellote isopod crustacean from interstitial spaces in shallow coralline sands off St. Eustatius, Caribbean Netherlands

The genus Microcharon is known in the Caribbean from the widely separated islands of Bonaire and Cuba, occurring in brackish and freshwater subterranean environments. Here we describe a new species from reef sands off St. Eustatius, eastern Caribbean. Morphological differences are small between the eleven other marine or coastal groundwater Microcharon species that are known worldwide, and comparisons do not show a biogeographic pattern of sequential dispersion.
