Ralph Holzenthal caddisfly (Rhyacophila lignumvallis) from Corsica in Rhyacophila tristis (Schmid 1970) group

NEWS - Ralph Holzenthal caddisfly ( Rhyacophila lignumvallis Graf & Rázuri-Gonzales, sp. nov.) from the island of Corsica (France) was established as a new species in the Rhyacophila tristis (Schmid 1970) group based on morphological analysis and the mitochondrial cytochrome c oxidase subunit I (mtCOI), including sequences from 16 of the 28 species in the group. Rhyacophila Pictet 1834 with 814 living and 30 fossil species is the largest genus of caddisflies in the world, distributed mainly in the northern hemisphere, but also in temperate and tropical India and Southeast Asia. One of the groups is the R. tristis group in the branch Rhyacophila invaria . R. lignumvallis is most similar to Rhyacophila pubescens Pictet 1834, Rhyacophila tsurakiana Malicky 1984, Rhyacophila ligurica Oláh & Vinçon 2021, Rhyacophila harmasa Oláh & Vinçon 2021 and Rhyacophila abruzzica Oláh & Vinçon 2021. However, R. lignumvallis differs in the shape of the X tergum, the dorsal arm ...
