Berosus interstitialis is a species of hydrophilid beetles from the Bahamas, Haiti, Guadeloupe, the U.S. Virgin Islands, Puerto Rico and Cuba.

Widely distributed Caribbean species, so far recorded from the Bahamas, Haiti Guadeloupe, Virgin Islands Puerto Rico and Cuba (Van Tassell 1966, Orchymont 1946, Epler 2010, this paper). The species is here recorded for the first time from Cuba, due to the synonymy of Berosus stribalus with Berosus interstitialis.
