RESUMEN
The morphology of the larva, pupa, male, and female of Rhyacophila loeffleri Valladolid & Waringer, n. sp., from Austria, Czech Republic, France, and Italy is described. Data from molecular analysis are also provided, based on mitochondrial cytochrome c oxidase subunit I (mtCOI), including sequences from German and Swiss specimens, and compared with those of samples of the nominate species R. fasciata Hagen 1859, as well as with other species and subspecies in the Rhyacophila fasciata Species Complex: R. septentrionis McLachlan 1865, R. denticulata McLachlan 1879, R. sociata Navs 1916, R. kykladica Malicky & Sipahiler 1993, R. delici Kuini & Valladolid 2020, R. fasciata viteceki Valladolid & Kuini 2020 and R. macedonica Karaouzas, Valladolid & Ibrahimi 2022. Our study revealed morphological differences between R. fasciata and R. loeffleri, as well as genetic differences among the other taxa of the R. fasciata Complex, supporting the recognition of R. loeffleri as a new species. Also, Rhyacophila fasciata viteceki is recognized as a distinct species, R. viteceki (status promotus), based on results of the molecular analysis.

The presence and distribution of Rhyacophila fasciata Hagen 1859 in Europe were revised, based on bibliographic study, collection specimens, and new material collected in different countries. The status of formerly synonymized species, Rhyacophila ferruginea (Scopoli 1763) and Rhyacophila septentrionis McLachlan 1865 was also assessed. The type of R. ferruginea is missing, the taxon is still unidentified, and thus we propose Rhyacophila ferruginea as a nomen dubium. Morphological features and genetic evidence revealed that R. septentrionis differs from R. fasciata, so we propose to change its status to status resurrectus. We therefore include new descriptions of the different stages (larva, pupa, male, and female) of R. fasciata and of R. septentrionis, together with a molecular analysis based on mitochondrial cytochrome oxidase I (mtCOI) and ecological notes. The species R. coppai Oláh 2020 NEW SYNONYM and R. soreda Coppa Oláh 2020 NEW SYNONYM are synonyms of R. sociata Navás 1916; the species R. kopasa Oláh Coppa 2020 NEW SYNONYM and R. rova Oláh Coppa 2020 NEW SYNONYM are synonyms of R. denticulata McLachlan 1879; the species R. matrensis Oláh Szczesny 2020 is probably a synonym of R. fasciata, so more study of this species is needed in order to confirm or deny that it is a valid species.

We present the description of two new subspecies of the Rhyacophila fasciata Group: Rhyacophila fasciata delici Kucinic Valladolid (ssp. nov.), broadly distributed in Croatia and present also in Bosnia and Herzegovina, and R. fasciata viteceki Valladolid Kucinic (ssp. nov.), found in Bosnia and Herzegovina. Our study of the morphology of adults, as well as our analysis of the barcode region of the mitochondrial cytochrome oxidase I (mtCOI) gene and geographical distribution confirm the differences of the two new subspecies with the nominal species R. f. fasciata, also found in both countries.
