A freshwater lobose rhizopod Cochliopodium vestitum (Archer, 1871) (Himatismenida) was re-isolated and studied. New diagnosis for this species, based on the light-and electron-microscopic data is provided. The most peculiar feature of this species is fine spines visible with light microscopy, which originate from the top of some of the scales comprising the tectum, as revealed with electronmicroscopy. Comparison of C. vestitum with the other spine-bearing cochliopodiums (C. echinatum and C. longispinum) suggests synonymy of these species, and C. vestitum remains the only valid spine-bearing Cochliopodium.
