Stygobiont ostracods from a deep cave Njemica (Biokovo Mt., Croatia)

Njemica cave on Biokovo Mountain is the fifth deepest pit in the Republic of Croatia (-936 m). It is primarily a vertical speleological object characterized by the alternation of spacious large halls and large verticals. At the bottom of the pit is a deep siphon lake with an unclear hydrological regime. From the deepest part of the pit in March 2021, sampling was conducted in the hall at the bottom of the pit. Two micro-locations were selected. The first location is situated nearby an underground bivouac at the depth of 930 meters. The second sampling site is situated nearby siphon lake at the very bottom of Njemica cave. Sub-recent ostracods were found within the sediment. Numerous ostracods of one endemic species of the family Cyprididae - Pseudocypridopsis sywulai Petkovski, Scharf, and Keyser, together with a small number of the juvenile specimens of the family Candonidae - Phreatocandona cf. motasi Danielopol were identified in all samples.
