N2 - The circumscription of the choanoflagellate genus Pleurasiga (fam. Acanthoecidae) is problematic in that the generic type, P. orculaeformis Schiller, 1925, is incompletely described and has not been found again. A reinvestigation of two species hitherto referred to this genus (P. minuta Leadbeater, 1972, and P. cupula Leadbeater, 1972) has shown that they are too different from other species of Pleurasiga to remain within the genus. One of them is referred to a new monotypic genus. Nannoeca gen.n., as Nannoeca minuta (Leadbeater) comb.n., whereas the other is transferred to the genus Stephanoeca [S. cupula (Leadbeater) comb.n.].
