L. polylepis is only found in one location, Stanicka Jaruga, a stream 1 m wide and 2 km long (area of occupancy (AOO) <10 km² and extent of occurrence (EOO) <100 km²). There is also a continuing decline of AOO, habitat quality and mature individuals due to water extraction and introduced trout species.
