REMARKS Two Other species of Microcharon have been described from the 

 Caribbean area: M. phreaticus Coineau and Botosaneanu, 1973, from intersti- 

 tial freshwater on Cuba, and M. herrerai Stock, 1977, from freshwater wells on 

 Bonaire. The reader should refer to the original descriptions to distinguish 

 these species.
