Two new species of rotifers belonging to the Dicranophoridae are described from marine psammon collected at a depth of 30–40 m in the Mediterranean near the island of Elba, Italy. Myersinella uncodonta sp. nov. is characterized by two colourless eyespots; single, incurved acute apical rami teeth; two needle-shaped, slightly incurved elongate unci; manubria with forked head and crutched cauda; outer margin of rami angular postero-laterally. Myersinella longiforceps sp. nov. is characterized by two large red eyespots; a pair of extremely elongated, gouge-shaped apical rami teeth; two short, needle-shaped unci; manubria with forked head and double-crutched cauda; outer margin of rami rounded laterally, tapering towards fulcrum. This is the first report of the genus Myersinella from marine environments.
