Maxillary barbel length is much longer on average, although there is some overlap. Anterior mandibular barbels are always longer than posterior mandibular barbels.

Distribution: Caspian and Urmia Lake basin ( Fig. 397). Found in Chamkhale, Siahdarvishan, Sefidrud, Zarinehrud and Aras Rivers as well as Anzali Wetland. It has also been reported from other southern and southeastern rivers of the Caspian Sea basin some years ago but nowadays it is only found in western and southwestern Caspian Sea Rivers.
