Phylogenetic and population genetic research of the past two decades has revealed that there are in fact nine (9) distinct and mostly allopatric species. Five of them already have names made available by the original describer, Fitzinger in 1850 (P. carrarae, P. freyeri, P. haidingeri), and Sket and Arntzen in 1994 (P. parkelj). In this contribution we describe the remaining four new species – P. sketi from Istria (Croatia), P. bosniacus from Bosanska Krajina (Bosnia and Herzegovina), P. croaticus from Lika (Croatia) and P. scopolii from the subterranean basin of the Reka/Timavo River (Slovenia, Italy).20262026-11-02 12:23:14Članek v reviji190722sl
