Rhyacophila fasciata Hagen Rhyacophila fasciata Hagen, 1859: 153. Lectotype: 1 male. Entomology 11067, Entomology Collection of the Museum of Comparative Zoology, Harvard University. Type locality: Elberfeld (Germany). Other information: (in label) 57; E.-illegible; Hagen; 107; ML; type 11067; (vial); Lectotype Rhyacophila fasciata Hagen. (MCZBase, 2020). (Figs 2a, 2b, 30a, 30b) Ross (1952) included the species in his publication about the lectotypes of Hagen in the collection of the Museum of Comparative Zoology at Harvard University, Cambridge, Massachusetts. Description. This species has been described by several authors over many years. The first publication where this species is cited is that of Hagen (1859), where he provided a very short description: “A. Lower appendages undivided at the top. 1. The tongue-like extention of the last abdominal segment with an enlarged end. 5. R. fasciata Hag. The app. are very similar to the previous species (R. ferruginea Scop.), but the size of the animal is much more significant, and the upper wings have three dark cross bands. A single male from Elberfeld” (Fig 30a).” McLachlan (1868) described it as follows: “ R. fasciata Hagen, may be distinguished almost with certainty by the dark fasciae on the anterior wings. The form of the dorsal lobe is very distinct from the preceding (R. paupera), being broad and rounded, and nearly concealing the app. sup. The second joint of the app. inf. is obliquely truncate (Pl.XIV. fig. 16). I have three ♂ from Carinthia from Zeller.” In 1879, McLachan described R. fasciata and R. septentrionis. In the description of R. fasciata he included the original specimen from Elberfeld, his specimens from Carinthia, saying that they should be referred to septentrionis, and 7 ♂ and 1 ♀ from the Pyrenees (France), writing “it may be that these should form a distinct species”. These specimens from the Pyrenees were described in 1916 by Navás as Rhyacophila sociata (Valladolid et al. 2018). On the other hand, in the description of R. septentrionis McLachlan included his specimens from Scotland, as well as others from different countries of North and Central Europe. Based on results of our studies of morphology and genetics, we can say that most of the specimens cited belong to R. fasciata, keeping only those from Scotland as R. septentrionis. Klapálek (1893) described the larva and the pupa of R. septentrionis in Bohem, but the area matches with those of R. fasciata, so it should be this species. The same situation pertains to Silfvenius (1905), who described larvae and pupae from South Finland as R. septentrionis that should be R. fasciata. Ulmer (1909), based on previous authors, described the imagos and larvae of R. fasciata and R. septentrionis, first one from Elberfeld and the second one from different places in Germany. We consider that these specimens all belong to R. fasciata. There are more recent authors that have described R. fasciata and R. septentrionis specimens: Nielsen (1942) as R. septentrionis from Denmark; Nóvak (1963) as R. fasciata from Czechoslovakia; Hickin (1954) and Mackereth (1954) as R. septentrionis from United Kingdom; Fotius-Jaboulet (1964) as R. septentrionis from France; Lepneva (1964) as R. septentrionis from northwest, west and southwest Russia; Eidel (1974) as R. fasciata from Austria; Buholzer (1978) as R. fasciata from Switzerland; Sedlak (1985) as R. fasciata from Central Europe; Pitsch (1993) as R. fasciata from Central Europe. Of all these descriptions, only those from the United Kingdom could belong to R. septentrionis; the rest, from continental Europe, should be R. fasciata or some related species. Finally, Malicky & Sipahiler (1993) illustrated the differences among male specimens of R. fasciata from Europe, Turkey, and Lebanon that they considered as subspecies of the R. fasciata Group. Some of them have been promoted to species (R. denticulata McLachlan 1879, by Valladolid et al. 2018; R. kykladica Malicky & Sipahiler 1993, by Valladolid et al. 2019), one species has been resurrected (R. sociata Navás 1916, previously a synonym of R. denticulata, by Valladolid et al. 2018), and others could be considered also valid species (Valladolid, unpublished data)., Published as part of Valladolid, María, Arauzo, Mercedes, Chertoprud, Mikhail V., Chvojka, Pavel, Czachorowski, Stanisław, Dorda, Beatriz A., Hinić, Jelena, Ibrahimi, Halil, Karaouzas, Ioannis, Krpač, Vladimir, Kučinić, Mladen, Lodovici, Omar, Salokannel, Juha, Stamenković, Valentina Slavevska & Stojanović, Katarina, 2021, 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.)., pp. 1-57 in Zootaxa 4975 (1) on pages 14-15, DOI: 10.11646/zootaxa.4975.1.1, http://zenodo.org/record/4804044, {"references":["Hagen, H.

[EN] We present the description of two new subspecies of the Rhyacophila fasciata Group: Rhyacophila fasciata delici Ku¿ini¿ & Valladolid (ssp. nov.), broadly distributed in Croatia and present also in Bosnia and Herzegovina, and R. fasciata viteceki Valladolid & Ku¿ini¿ (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., [ES] Se presenta la descripción de dos nuevas subespecies del Grupo Rhyacophila fasciata: Rhyacophila fasciata delici Kučinić& Valladolid (ssp. nov.), ampliamente distribuida en Croacia y presente también en Bosnia y Herzegovina y R. fasciata vitecekiValladolid & Kučinić (ssp. nov.), encontrada en Bosnia y Herzegovina. El estudio de la morfología de los adultos, así como el análisis de la citocromo oxidasa I mitocondrial (COImit) y la distribución geográfica confirma las diferencias de las dos nuevas subespecies con la especie nominal R. f. fasciata, también presente en ambos países., This research is a part of scientific project “DNA barcoding of Croatian faunal biodiversity” (IP–06–2016–9988) funded by the Croatian Science Foundation.

[EN] The morphology of the different stages (larva, pupa, male, and female) of Rhyacophila fasciata kykladica Malicky & Sipahiler 1993 was examined as a basis for the description of the taxon. Morphological data were supplemented by molecular analysis of mitochondrial cytochrome C oxidase subunit I (mtCOI), which were compared with samples of the nominate subspecies Rhyacophila fasciata fasciata Hagen 1859, as well as with other new species in this group, Rhyacophila denticulata McLachlan 1879 and Rhyacophila sociata Navás 1916. Our results revealed genetic differences between all the taxa; therefore, a change of taxonomic status of R. fasciata kykladica to R. kykladica (stat. prom.) is proposed., [ES] Se ha estudiado la morfología de los diferentes estadíos (larva, pupa, macho y hembra) de Rhyacophila fasciata kykladica Malicky & Sipahiler 1993, con el fin de completar la descripción del taxón. Los datos morfológicos se complementaron con el análisis del gen de la citocromo C oxidasa mitocondrial, subunidad I (mtCOI), que se comparó con muestras de la subespecie nominal Rhyacophila fasciata fasciata Hagen 1859, así como con otras especies nuevas en este grupo, Rhyacophila denticulata McLachlan 1879 y Rhyacophila sociata Navás 1916. Nuestros resultados revelaron diferencias genéticas entre todos los taxones, por lo que se propone un cambio de estatus taxonómico de R. fasciata kykladica a R. kykladica (stat. prom.).

In order to check the presence and distribution of Rhyacophila fasciata fasciata Hagen 1859 (species described from Austria) and R. fasciata denticulata McLachlan 1879 in the Iberian Peninsula, we studied the morphology of Spanish, French, and Austrian specimens, together with their mitochondrial cytochrome c oxidase (mtCOI). We observed that the individuals considered to date as R. fasciata denticulata are in fact two different species: R. denticulata, presently known from France and possibly in some rivers of the Basque Country (Spain), and R. sociata Navás 1916 distributed in Spain and France. These two species are also different from the reference species (R. fasciata) from Austria, so we propose a change in the taxonomic status of R. fasciata denticulata to R. denticulata (stat. prom.) and the restoration of R. sociata (stat. res.), with the designation of a neotype, due to the loss of the holotype., This study was funded by the Projects AGl2006-07087/AGR (Plan Nacional I+D+I 2006) and AGL2011-29861/AGR (Ministerio de Ciencia e Innovación, Plan Nacional I+D+I (2008-2011)).
