A New Record of Paracobitis rhadinaea (Regan, 1906)

After around a hundred years of being without any record of occurrence of Paracobitis rhadinaea, a species of Nemacheiline loach, in Sistan basin, southeast of Iran, the year 2012 was the turning point of wild life in this area. Twenty-five specimens were caught from Chahnimeh Reservoir, a water body adjacent to the Hamoun Wetland in Sistan basin. Morphometric and meristic characteristics were measured.
