Abstract
Nullosetigeridae nom. nov, is proposed for Phyllopodidae Brodsky, 1950, nom . nud., and Nullosetigera nom. nov. is introduced for Phyllopus Brady, 1883 , non Rafinesque, 1815. A new species, Nullosetigera auctiseta, is describe d from Japanese waters. Nullosetigera mutica comb. nov. (Sars, 1907) and N. mutata comb, nov. (Tanaka, 1964) are redescribed. Phylogenetic analysis im plies that two groups, N. auctiseta-N. mutica group and N. mutata-N. impar- N. bidentata-N. helgae group, exist within the genus Nullosetigera and that the new species first diverges with N. mutica. The relatively advanced spe cies, N. impar, N. bidentata, and N. helgae are the most widespread, and ar e vertically distributed from the epipelagic to the bathypelagic layers.
