Sažetak
This paper presents data analysis of spatial distribution of cave terrestrial isopods in Croatia. Data were analyzed through UTM grid map of Croatia (10 x 10 km) and macroregions according to Roglić, 1974, taking into account endemics and adaptation to cave habitats. In Croatia 129 species and 32 subspecies of terrestrial isopods have been recorded to date, 58 species and 18 subspecies being endemic to Croatia. More than 9000 caves have been registered in Croatia, but only for 211 caves (~2.3%), and 14 different habitat types literature data were gathered. Altogether, with data from collections, this paper presents records from 502 (~5.6%) caves, 5 mines and 19 different habitat types. Among cave taxa, 34 species and 7 subspecies have been registered, belonging to five families and six subfamilies. The family Trichoniscidae and subfamily Trichoniscinae are the most abundant. Out of 22 Croatian endemic taxa 13 (59%) belong to the subfamily Trichoniscinae. Out of 20 troglobitic species, 15 (75%) belong to the subfamily Trichoniscinae. The most represented seemed to be the genus Alpioniscus with 10 species, followed by the genus Androniscus with 9 taxa. Out of 814 Croatian 10x10 km UTM squares only 149 (~16 %) have one or more cave species of terrestrial isopods and most of them are scattered all over the Dinaric region in Croatia. The UTM plot VL41 presents extreme with 6 species, belonging to the Northern Croatian Littoral macroregion. The UTM plots BN71, YH03 and YH13 have 5 species, belonging to the Southern Croatian Littoral macroregion. Out of 41 cave taxa in Croatia the Southern Croatian Littoral macroregion has 27 (~66%) and the Northern Croatian Littoral macroregion has 14 (~34%). Out of 22 endemic cave taxa in Croatia, the Southern Croatian Littoral mesoregion has 15 (~68%), and among them, 2 are widespread and 14 are endemic to that region. Out of 79 Croatian islands and 523 small islands there are records of terrestrial isopods for 9 islands. Seven islands have their own endemic species (10 species). The island of Mljet presents the extreme with 3 endemic species. Out of 41 cave taxa in Croatia, all are distributed in the Dinaric karst area, with just 3 troglophilic species distributed outside the Dinaric karst area. There are no Croatian endemic taxa outside the Dinaric karst area.
