20.500.12556/RUL-190735 Niphargus entlebuchensis sp. nov., a new subterranean amphipod species (Crustacea, Amphipoda, Niphargidae) restricted to a karst area in Central Switzerland Groundwater ecosystems are of high interest to both taxonomists and ecologists for their high diversity as well as pronounced biogeographic patterns of occupying organisms persisting across major geological time periods, such as glaciation cycles. Over the last years, coordinated efforts increased the knowledge on the diversity and distribution of stygofauna in Switzerland, particularly the order Amphipoda, revealing several new species with highly localized occurrences. Thereby, citizen science approaches and collaborations with both cavers and drinking water providers have greatly increased the available data. As a result of these activities, we here describe another new species of the genus Niphargus Schiödte, 1849, namely Niphargus entlebuchensis sp. nov. Molecular and morphological species delimitation analyses both clearly support its species status. Multi-marker phylogenetic analyses recover the new species within a clade that comprises several other Swiss species, such as N. luchoffmanni Fišer et al., 2018 and N. muotae Fišer et al., 2017, while the internal structure of the clade received weak support. So far, the species has only been found in a single karst mountain ridge in Central Switzerland, suggesting that it is a narrow-range endemic. biodiversity citizen science groundwater Niphargus stygofauna taxonom biodiverziteta občanska znanost podzemne vode Niphargus stigofauna taksonomija true false true Angleški jezik Slovenski jezik Članek v reviji 2026-11-02 13:25:36 2026-11-02 13:25:36 2026-11-03 04:08:29 0000-00-00 00:00:00 2026 0 0 Str. 115-136 Vol. 58 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 551.44 1314-2615 10.3897/subtbiol.58.209466 303373827 RAZ_Knusel_Mara_2026.pdf RAZ_Knusel_Mara_2026.pdf 1 4705E0B1ED235DFC8A2FBDFDD56BA7CA fddf118ecb9d94bd8eb201ef8f06be95610fc0d10baf6cdbd9704cf2d176dc19 afefb6e0-d6b8-11f1-aea2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=252331 https://subtbiol.pensoft.net/article/209466/ 0 a7931d87-d6b8-11f1-aea2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=252330 Biotehniška fakulteta 0 0 0
