The Rhyacophila fasciata Group in Europe: Rhyacophila fasciata Hagen 1859 and formerly synonymized species (Trichoptera: Rhyacophilidae), with new description of Rhyacophila fasciata and Rhyacophila septentrionis McLachlan 1865 (stat. prom.).

Abstract

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 & Szczęsny 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.

A surprising finding of Ecclisopteryx asterix Malicky, 1979 (Insecta, Trichoptera) in Croatia with notes to DNA barcoding and new distributional data of the subfamily Drusinae

“…Thus, our study further indicates that the DNA barcoding method is a valuable tool in faunistic, taxonomic and biodiversity research, as already implemented in other studies in Croatia (e.g. Cerjanec et al 2020;Kučinić et al 2020;Szivák et al 2017;Valladolid et al 2020;Vučković et al 2021) and other countries (e. g. Ibrahimi et al 2021;Morinière et al 2017;Valladolid et al 2019Valladolid et al , 2021Zhou et al 2007Zhou et al , 2016.…”

“…Establishment of the BOLD database in 2007 (Ratnasingham & Hebert 2007) enabled the use of the obtained sequences (DNA barcodes) in the sequence analysis for taxonomic and phylogenetic research, which has both local and global value (Brehm et al 2019;Cárdenas et al 2013;Elías-Gutiérrez et al 2008;Léger et al 2020;Tyagi et al 2017). In the last 10 years, a significant number of papers have been published that include DNA barcoding of Trichoptera (Geraci et al 2011;Morinière et al 2017;Szivák et al 2017;Valladolid et al 2018Valladolid et al , 2021Zhou et al 2016), and a certain part of these also refer to the Croatian fauna (Ćukušić et al 2017;Kučinić et al 2013Kučinić et al , 2016aKučinić et al , 2017aKučinić et al , 2019aKučinić et al , 2019bValladolid et al 2020).…”

The InBIO barcoding initiative database: DNA barcodes of Iberian Trichoptera, documenting biodiversity for freshwater biomonitoring in a Mediterranean hotspot

“…Furthermore, this BIN includes all publicly available sequences in BOLD identified as R. adjuncta and R. sociata , including all sequences generated by Valladolid et al (2018) . In their paper, the authors did not investigate a possible relationship between these two species, nor was that relationship assessed in a subsequent study on the European species of the R. fasciata group ( Valladolid et al 2021 ). Finally, the BIN mentioned above also includes other sequences identified as R. tristis Pictet, 1834. and R. fasciata Hagen, 1859, although these are probably misidentifications.…”

Rhyacophila siparantum sp. nov. (Trichoptera: Rhyacophilidae), a new species of the R. philopotamoides species group from the Republic of Kosovo with molecular and ecological notes

“…Rhyacophila Pictet, 1834, the largest genus of the Rhyacophilidae family, with more than 800 described species (e.g. Schmid 1970;González & Menéndez 2010;Oláh 2010;Kiss 2011Kiss , 2013Holzenthal et al 2015;Oláh & Beshkov 2016;Valladolid et al 2020Valladolid et al , 2021, is distributed in the Nearctic, Oriental and Palearctic regions. While many species of this genus are widely distributed in different habitats of freshwater ecosystems, other species are restricted to narrow areas.…”

“…The genus Rhyacophila is considerably diverse in the Southeastern Europe, with many microendemic taxa. Several new taxa of this genus have been described during the past years from this area, such as: Rhyacophila acutila Oláh, 2010, Rhyacophila liutika Oláh, 2010, Rhyacophila olahorum Oláh, 2016, Rhyacophila neretva Oláh, 2016, Rhyacophila nurga Oláh, 2016, Rhyacophila fasciata delici Kučinić & Valladolid, 2021, Rhyacophila fasciata viteceki Kučinić & Valladolid, 2021, etc. Species of the genus Rhyacophila do not construct larval cases and move freely on the bottoms of streams and rivers. Most of the species have predatory larvae, while few species feed on material of plant origin.…”
