Salsuginus bermudae sp.n. is described from gills of mangrove minnow, Fundulus bermudae Gunther, and mosquito fish, Gambusia affinis (Baird and Girard), from Bermuda. It differs from S. angularis by its shorter ventral hamuli (20–23 versus 22–26 μm); from S. fundulus, S. spirae, and S. heterocliti by its shorter dorsal and ventral hamuli (17–21 versus 22–26, 22–26, 20–24 μm, respectively, for dorsal hamuli and 20–23 versus 23–29, 23–27, 25–28 μm, respectively, for ventral hamuli); from S. bahamianus by its longer ventral hamulus superficial root (6–10 versus 5–6 μm); and from S. umbraensis by its shorter dorsal hamuli and dorsal bar (17–21 versus 23–24 and 19–26 versus 30–31 μm, respectively). It is indistinguishable morphometrically from S. seculus, yet differentiable from other species of Salsuginus by its dorsal and ventral hamuli and by its accessory piece. Mangrove minnows may be distributed in separate populations in the various Bermudian lakes. Differences in accessory piece morphology allowed discrimination of two morphotypes isolated in separate small mangrove minnow populations from two lakes (Mangrove and Lover's) which have different physicochemical characteristics. A possible isolating mechanism is discussed.
