Description of the type locality

Eupolybothrus cavernicolus Komeri?ki & Stoev sp. n. is so far known only from the caves Miljacka II and Miljacka IV (= ?pilja kod mlina na Miljacki), situated near the village of Kistanje, Krka National Park, Knin District, Croatia (Fig. 12). The two caves are situated close to each other and are formed in Middle Eocene to Early Oligocene conglomerate and marbly limestone. Miljacka II is the longest cave in the Krka National Park, with a large, spacious entrance and a total length of over 2800 m (Fig. 13). Most of the cave passages are under water except for approx. 300 m of main passage. From a hydrogeological point of view, cave Miljacka II contains a periodical spring, while cave Miljacka IV has a permanent water flow. The cave Miljacka IV has two entrances, one dry and one underwater, and a length of approximately 43 m. The land entrance is walled in and with a small door while inside the cave there is a thick drywall separating it in two parts. The climatic conditions in Miljacka II as measured on 4th May 2010 and 8th October 2010 are as follows: Tair = 12.5-13.7°C (Kestrel); RH = 100%; Tsediment = 12.5-13.2°C; Twater = 12.6-13.2°C; in Miljacka IV (measured on 4 May 2010): Tair = 13.1-13.6°C (Kestrel); RH = 100%; Tsediment = 12.5°C; Twater = 12.5°C. In Miljacka II, the specimens were collected in the aphotic zone, approx. 50 m from the cave entrance, in a passage where water never occurs in a periodic flow. In Miljacka IV, they were found closer to the entrance, under stones.
