The West Indian Spiny Rats (family Echimyidae) are represented on Hispaniola by the genus Brotomys, with two nominal species (B. voratus from the Dominican Republic and B. contractus from Haiti). 

      The genus is closely related to Spiny Rats of the genus Heteropsomys (Puerto Rico) and Boromys (Cuba). B. voratus has been claimed to have gone extinct within "the last 50 years" but this has not been supported with published radiometric evidence.
