Freyhof et al. recently published an article in Zootaxa. Oxynoemacheilus phasicus, new species, is described from the Rioni and Enguri River drainages in Georgia. Oxynoemacheilus phasicus is distinguished by molecular data (COI) and from other Oxynoemacheilus species in the O. brandtii group by a mottled or marbled flank pattern in adults, a slightly emarginate caudal fin, and a deep caudal peduncle.
