An overview on the Croatian spider fauna

The creation of the most comprehensive checklist of spider fauna of Croatia is ongoing and almost completed. Currently, 644 literature references, including grey literature, data from 19 museum collections (7 of which were visited by authors for redetermination of questionable and determination of unidentified material) and several unpublished records from CBSS (Croatian biospeleological society) and CARS (Croatian Arachnological Society – Narcis Damin) collections are analysed. The checklist is currentlycomprised of 19314 literature species records, 4831 museum records and several new records. It must be noted that Croatian Natural History Museum’s collection from Zagreb, with more than 2400 spider records, is not yet included in the list. More than 2500 different locality names were recorded with more than 1500 unique localities. Around 6000 different taxa names were recorded with more than 790 valid species and subspecies, belonging to 44 families. 88 taxa were excluded from the list or marked as questionable. Analyses of research intensity through time, from 1774 till today, and general species distribution is finished. Composition of Croatian spider fauna was compared to the neighbouring countries. At the moment Fauna Europaea database lists 719 spider taxa for Croatia (Van Helsdingen 2015). With this work the total count will rise to almost 800 taxa, but the number is far from complete.
