The karst areas in Croatia, part of the Dinarides, have been defined biospeleologically as an area of high biodiversity in world terms, covering 26 thousand km2 in all. In this monograph we give data about the biodiversity of subterranean habitats and their biota primarily from a taxo- nomic perspective with special attention being paid to regional diversity. The diversified geomor- phology, hydrology and climate have resulted in a remarkable range of different underground hab- itats in Croatia, viz. inland and coastal caves, superficial and deep phreatic networks, interstitial – hyporheic substrates and other infiltration zones, etc. In Croatia more than 500 obligate subterra- nean species and subspecies are known from caves and interstitial habitats. The majority of subter- ranean species in Croatia are terrestrial biota. There are 299 troglobiont and 170 stygobiont taxa (species and subspecies) recorded. Most subterranean species have very restricted ranges, almost Croatian Natural History Museum, Demetrova 1, Zagreb, Croatia 2 Gottstein Mato~ec, S. (ed.): An overview of the cave and interstitial biota of Croatia 70% of them endemic to Croatia. Cave fungi are poorly known. Among them there are several im- portant parasitic troglobionts and troglophilic species on cave coleopterans and troglophilic moths in Croatian caves. Some saprotrophic species could be troglobiotic too but their taxonomic and/or ecological status must be clarified in future research. With a respect to the number of troglobionts, the five largest animal groups are Coleoptera, Pseudoscorpiones, Araneae, Gastropoda and Di- plopoda. The beetles (Coleoptera) are predominant. More than 100 cavernicolous beetles (species and subspecies) are known in Croatia. Among stygobionts, the Crustacea predominate. At least half of species described are Crustacea. Among Crustacea, the orders Syncarida and Thermosbae- nacea are exclusively stygobiotic. Numerically, among crustacean stygobiotic Amphipoda dominate in caves and Copepoda in interstitial habitats. The only known stygobiotic sponge Eunapius sub- terraneus Sket et Velikonja inhabits several caves in Croatia. Also, the only known stygobiotic clam Congeria kusceri Bole inhabits a series of caves in
