A trait database for European subterranean spiders

Database of traits for European cave spiders, available as an Excel file (.xlsx) or a tab-delimited file (.csv). See Metadata file for an explanation of the columns.The database is described in detail in the following publication (Version 1):Mammola S., et al. 2022. A trait database and updated checklist for European subterranean spiders. Scientific Data, doi: 10.1038/s41597-022-01316-3and further updates (Version 3):Patiño-Sauma D., et al. (2025). Another brick in the wall of European subterranean spider knowledge: adding Macaronesian species and their traits to the picture. EcoEvoRxiv.----------------------------------------------------------------------------Updated database to Version 2 on 27 Jan 2023.Changelog:1) Corrected a few typos in formatting2) Measured some missing traits in Eidmannella pallida, Heteropoda variegata, Loxosceles rufescens, and Tegenaria pagana3) Added missing species Phyxelida anatolica----------------------------------------------------------------------------Updated database to Version 3 on 10 Nov 2025.Major update of the dataset following the publication of Patino-Sauma et al. (2025).Changelog:1) Included all Macaroensian species in the checklist. See the new sheet Macaronesian spiders for the list of species.2) Added new species from continental Europe—8 described since 2023, 5 previously overlooked, and 61 species under description.3) Added measures for missing sexes (the male of Cybaedoes magnus).4) Removed non-subterranean species which we erroneously inserted in the previous version of the checklist: Harpactea sanctidomini (only known from a single specimen in a pine forest; probably a soil-dwelling species).5) Updated taxonomy. Importantly, we removed species Hahnia caeca (now a synonym of Iberina microphtalma), Palliduphantes garganicus (now a synonym of Palliduphantes istrianus), Troglohyphantes affirmatus (now a synonym of Troglohyphantes marqueti), Troglohyphantes nyctalops (now a synonym of Troglohyphantes cantabricus), and Troglohyphantes montanus (which is considered a doubtful species).6) Corrected some typos and added a few missing traits for previously recorded species.7) Removed the trait "Dispersal" due to different problems in assessing it.<br>
