Polak, S. & Jalžić, B.: Revision of the genus Bathyscidius Jeannel, 1910 (Coleoptera: Leiodidae: Cholevinae: Leptodirini), with a description of a new subgenus and three new species from Croatia and Montenegro. Nat. Croat., Vol. 28, No. 2., 359-402, 2019, Zagreb. The genus Bathyscidius is, according to the body size, one of the smallest leptodirines. Six species, one of them including two subspecies, have been described to date. This study has undertaken a taxonomical revision of the genus Bathyscidius s. str. Existing species are re-described, supported with detailed morphometry and, for the first time, with the description of male and female internal morphological characters. Three newly discovered species B. mljetensis, B. komajiensis and B. orjensis are described; one subspecies B. t. fallaciosus is elevated to species rank and one of the existing species B. remyi is synonymized. For the two geographically isolated species, B. rambouseki and B. tomoricensis, a new subgenus, Ionobathyscidius, is established.
