Overview of cave spiders in Croatia – 150 years of research

Cave spider research in Croatia goes back to 1862 when Keyserling described first troglobiotic species forCroatia, Hadites tegenarioides. Władysław Kulczyński described three and Josef Kratochvil, a famous Czech arachnologist, described 14 cave species, some of them with Karel Absolon and František Miller. Most recent explorer was Christa Deeleman-Reinhold who described six species. From the faunistic point of view, except for already mentioned authors, Paolo Marcello Brignoli also contributed. At the present time researchers from Croatian Biospeleological Society (CBSS) perform systematic work in this field. Of approximately 9000 explored caves in Croatian karst (prediction is three times as much), CBSS collection holds spider material from about 1000 of them. At the moment 115 hypogean taxa are recorded from caves in Croatia, 90 of which are true cave taxa (43 troglobionts, 47 troglophiles), 9 are subtroglophiles and 16 microcavernicolus.Most abundant families are Linyphiidae (46species), Dysderidae (16), Agelenidae (13 and Leptonetidae(10). Thirty-five species are described fromCroatia and 27 are endemic. Of 90 cave taxa, 23 (13troglobionts) are probably new for science and waitingto be described.
