Rzadkie i zagrożone gatunki Rhyacophila philopotamoides McLachlan, 1879 i Agapetus laniger (Pictet, 1834) (Trichoptera: Rhyacophilidae, Glossosomatidae) w Beskidzie Sądeckim

A new locality of two very rare caddisflies Rhyacophila philopotamoides McLachlan, 1879 and Agapetus laniger (Pictet, 1834) was found in Muszyna on the Poprad River in Beskid Sądecki. These species were found in Poland 40 years ago. A. laniger is on the red list of endangered species in the ”near threatened“ category (NT). In the case of R. philopotamoides, it is worth considering its listing given the small area of occurrence and the single number of individuals observed.
