A lot or not? A review of 200 years of spider research in Croatia

Through 200 years of spider research in Croatia, 719 spider species were recorded. The first written record of spider species for Croatian territory was given by Alberto Fortis in 1774, mentioning two "dangerous spiders which can cause painful bites". First publication of spider survey was published in 1817, marking beginning of interest in Croatian spider fauna. As a part of the PhD thesis "Spiders of Croatia and analysis of the environmental determinants of their distribution", a revision of the spider checklist of Croatia and georeferencing of all known records is in progress. A review of publications as well as survey of museum collections containing spider records from Croatia is ongoing, accompanied with redetermination of questionable and unidentified material. References from the historical checklists of Croatian araneofauna and other publications known to mention spider records from Croatia were listed in the database. Secondly, arachnologists were contacted through the mailing lists of the International Society for Arachnology and European Society for Arachnology, in search of literature references for which they know to contain information about records of spiders from Croatia. Online databases were used to search and download listed literature references, but also to find new ones. Similar procedure was done for identifying museum collections containing Croatian spider material. Altogether more than 520 publications, mainly from foreign authors, mentioning spider records from Croatia have been identified. So far, 60% of the publications have been processed, resulting in 6, 800 records stored in the database. 45 museums and institutions were contacted, out of which 25 were identified to have relevant spider material, counting more than 6, 000 records. Based on current analysis, the number of recorded species is close to 800. Upon the collection of existing records, a georeferencing of all records without precise coordinates will be carried out using specifically designed online application.
