Additional material of a rare scorpion species Protoiurus kadleci (Kovařík et al., 2010) from Turkey (Antalya Province) was examined, in particular, sexually mature males. New information is presented on the morphometric differences between adult and subadult males of this species, and on the differences between P. kadleci and other species of Protoiurus. An updated diagnosis of P. kadleci is presented, as well as updated key to six species of Protoiurus, and a map showing all known localities.
