The presence of P. biaurelia and P. triaurelia was recorded in one habitat, i.e. the Prutec stream, in the village Mykulychyn, the Gorgany Mts. Especially interesting seems the finding of a new habitat of P. triaurelia in Ukraine, and the first time in the Carpathians. It extends its range in Europe to the east.
