Schizoyhorax pelzami is a member of Cyprinid family in the Dahst-e-kavir and Hari River basins of Iran. According to importance of osteological characters for taxonomy of fish species and lacking any information regarding osteological features of S. pelzami, this study was conducted to provide the detailed osteological characters. For this purpose, specimens were cleared and stained by alcian blue and alizarin red. Their skeletal structures were photographed using a scanner equipped with a glycerol bath. Drawing and nomenclature of the skeletal elements were done using Corel Draw X6 software and studied under a stereomicroscope. Base on the results, S. pelzami species is distinguished from other species of this genus by having (1) 44 vertebrae, (2) a long nasal bone, (3) an anal fin with anterior position (close to 27th centrum), (4) a broader posterior part of basibranchial, (5) a flat posterior margin of urohyal and (6) lack a pre-palatine.
