20.500.12556/DiRROS-18942 Discovering unknown Madagascar biodiversity integrative taxonomy of raft spiders (Pisauridae: Dolomedes) Discovering unknown Madagascar biodiversity: integrative taxonomy of raft spiders (Pisauridae: Dolomedes) Madagascar is a global biodiversity hotspot, but its biodiversity continues to be underestimated and understudied. Of raft spiders, genus Dolomedes Latreille, 1804, literature only reports two species on Madagascar. Our single expedition to humid forests of eastern and northern Madagascar, however, yielded a series of Dolomedes exemplars representing both sexes of five morphospecies. To avoid only using morphological diagnostics, we devised and tested an integrative taxonomic model for Dolomedes based on the unified species concept. The model first determines morphospecies within a morphometrics framework, then tests their validity via species delimitation using COI. It then incorporates habitat preferences, geological barriers, and dispersal related traits to form hypotheses about gene flow limitations. Our results reveal four new Dolomedes species that we describe from both sexes as Dolomedes gregoric sp. nov., D. bedjanic sp. nov., D. hydatostella sp. nov., and D. rotundus sp. nov. The range of D. kalanoro Silva & Griswold, 2013, now also known from both sexes, is expanded to eastern Madagascar. By increasing the known raft spider diversity from one valid species to five, our results merely scratch the surface of the true Dolomedes species diversity on Madagascar. Our integrative taxonomic model provides the framework for future revisions of raft spiders anywhere. raft spiders integrative taxonomic model Madagascar biodiversity integrative taxonomy zoology Dolomedes true false true Angleški jezik Latinski jezik Neznano 2024-05-16 15:09:05 2024-05-16 15:09:05 2024-05-23 11:41:45 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 21. 3. 2024; str. 1-60 [art. no.] ǂe16781 Vol. 12 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2024-02-27 591 2167-8359 10.7717/peerj.16781 189843203 https://doi.org/10.7717/peerj.16781 1 7c134ca7-1385-11ef-9c9e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25965 RAZ_Yu_Kuang-Ping_2024.pdf RAZ_Yu_Kuang-Ping_2024.pdf 1 9AB2CEA6CD33749C478C0BF09415EE70 0287f6d32072bec47d2bb2f2a29c6fa765f85c7efbb2a8a9acacc41d6e052911 bd6cf333-1385-11ef-9c9e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25966 Nacionalni inštitut za biologijo 0 0 0
