Only known from 2 caves in Kerkyra island. Beier (1929a) described Obisium (=Neobisium) odysseum from a specimen collected from an unnamed stalactite cave at Pantokrator Mt, Pantokrator above Barbati ["…1 adultes Exemplar, Korfu, in einer unbenannteng großen tropfsteingrotte um Pantokrator oberhalb von Barbati, etwa 200m ü M., 3.IV.1929…"]. This could be the cave Spilaio Katsouri.
