Abstract
Some osteological characters are studied in 40 species of seven genera and two families (Cobitidae and Nemacheilidae) of the loach fishes from Iran. The characters include: dorsal- and anal-fin formula, precaudal and caudal vertebrae, caudal skeleton, caudal-fin formula and suborbital spine. All these features, especially caudal skeleton, appear to be useful as a taxonomic tool in study of the loaches. Formulae for all characters were developed, relationships among the families, genera and species are discussed and monophyly of members of Cobitidae and Nemacheilidae is proposed.
