Species

About 60, see text

Cobitis is a Palearctic genus of ray-finned fish in the family Cobitidae. It contains the typical spiny loaches, including the well-known Spined Loach (C. taenia) of temperate western Eurasia. Containing almost 60 named species as of mid-2008, at least two undescribed ones are also known. Similar spiny loaches, occurring generally south of the range of Cobitis, are noadays separated in Sabanejewia.[1]

Species

Several Balkans populations were of doubtful status. They appear only weakly distinct from the Spined Loach, but cladistic analysis of DNA sequence data (nDNA RAG-1 and S7 ribosomal protein intron 1, and mtDNA cytochrome b) confirms that they are old lineages, properly treated as full species. The parapatric C. arachtoensis and C. hellenica are hardly different genetically and might be considered a single species.[2]
