A holistic perspective on species delimitation outperforms all methods based on single data types in freshwater gastropods (Caenogastropoda: Hydrobiidae: Pseudamnicola) Zool. J. Linn. Soc. (IF 2.8) Pub Date : 2024-03-05 Diana Delicado, Khadija Boulaassafer, Noureddine Khalloufi, Torsten Hauffe
Freshwater gastropods are one of the most species-rich and severely threatened animal groups in continental aquatic ecosystems. Unfortunately, understanding their species diversity, which is key to conservation, is often hampered by their small size, simple morphology, and restricted distribution. This is particularly the case for spring snails of the genus Pseudamnicola (family Hydrobiidae), a species-rich
