A new species of Protonemura Kempny, 1898 (Plecoptera, Nemouridae) from Albania

Although studies of the entomofauna of the Balkan Peninsula have increased in quantity and intensity over the course of the last decades, many areas are still not fully investigated regarding their faunistic inventory. As a result of a field trip in the Vjosa catchment in 2023, a new species of the genus Protonemura Kempny, 1898 (Plecoptera, Nemouridae, Amphinemurinae) is described from Albania, Protonemura eclipsis sp. nov. from a holotype male, collected from the District of Tepelenë, Bënçë River. The new species is compared and differentiated from related species, namely Protonemura albanica Raušer, 1963 and Protonemura miatchense Ikonomov, 1983. It differs from congeners clearly by its terminalia, namely the shape of the paraprocts. Images of the new species and of Protonemura albanica are provided.
