Austropotamobius bihariensis

Species of crayfish

Austropotamobius bihariensis is a species of crayfish in the family Astacidae. It is known to exist only in Romania being restricted to the rivers in the western Apuseni Mountains. Its proposed English common name is idle crayfish. It is supposed to have diverged/split ~15 Ma old from a common relative of A. torrentium from the Dinarides and evolved isolated due to the historically tectonic north-eastern movement of Tisza-Dacia mega-unit through the Pannonian Basin, during the Miocene. The molecular divergence in 582 base length nucleotides of COI mtDNA sequences is supported by 43 mutational steps, a differentiation of 7.4% from the sister clade of A. torrentium located in north-western Dinarides
