ABSTRACT: Three new species of calcareous sponges from Kuril Islands are described. Two of them belong to the formerly monotypic genus Leucopsila (L. pacifica sp.n. and L. hexactina sp.n.) and one to Leuconia (L. pilosa sp.n.). Family Baeriidae Borojevic, Boury-Esnault et Vacelet, 2000, to which these genera are currently assigned, is shown to be invalid. Valid name for this family is Leuconiidae Breitfuss, 1897. The molecular data assign the described species to the clade comprising chiactine and pugiole bearing sponges of Leuconiidae, Achramorphidae and Petrobionidae, supporting the current view that these families are closely related.

KEY WORDS: Baeriidae, Calcarea, Kuril Islands, Leuconia, Leuconiidae, Leucopsila, NW Pacific.
