Biospeleological Research of Pećina na Vrelu Mokranjske Miljacke Cave in Bosnia and Herzegovina

Pećina na Vrelu Mokranjske Miljacke Cave with the length over 6800 meters is almost the longest cave in Bosnia and Herzegovina, measured thus far. The cave is located in Romanija Mountain (near Mokro) on north edge of Dinarides, some 30 km east from capital Sarajevo. It is a hydrological active complex cave, with one active channel, the main channel and a lot of smaller lateral channels. There are a few fossil channels with the largest one, near to the entrance of the cave. Very interesting findings of archaeological artifacts but also Pleistocene fauna are discovered: almost complete cranial skeleton of young adult male cave bear (Ursus spelaeus Rosenmüller & Heinroth, 1794) and cranial skeleton of beaver (Castor fiber Linnaeus, 1758). During the recent research at the International speleological camp in 2009, a systematic biospeleological researches have been performed, using a water and terrestrial traps. A rich cave-dwelling fauna have been discovered from several groups: water and terrestrial snails (Gastropoda), spiders (Araneae), spring tails (Collembola), beetles (Coleoptera), but also very interesting taxa of tricladids (Tricladida), false spiders (Opiliones) and cicadas (Cicadomorpha), same as some parasitic fungi taxa. Among them, some taxa are considered to be a new species for science, most interesting new false spider genus, closely related to genus Hadzinia (Opiliones, Nemastomatidae). In future, research will proceed with further speleological but also biospeleological research combined with molecular genetic analyses.
