Ochthebius mediterraneus sensu Jaech (1991) (Coleoptera: Hydraenidae) is split up into three distinct species: Ochthebius mediierraneus (Ienistea, 1988) [west Mediterranean], O. magnannulatus sp.n. [east Mediterranean] and O. parvannulatus sp.n. [east Mediterranean]. Ochthebius pakistanicus sp.n. [Pakistan] is described. Ochthebius emilianus (Ienistea. 1988) is synonymized with O. medi-terraneus, and O. balcanicus (Ienistea, 1988) is synonymized with O. elburzi Ferro, 1987. Ochthebius mediterraneus is recorded from Croatia for the first time; the genus Ochthebius Leach (O. indicus (Ienistea, 1988)) is recorded from Bhutan for the first time. Ochthebius medius is formally elevated to species rank.
