Abstract

Oxynoemacheilus zagrosensis is one of the 17 known species belonging to the genus Oxynoemacheilus in Iran that have been reported. This species is native to Iran and reported in the Choman River from the Tigris River. This species is morphologically very similar to its sympatric species, O. chomanicus. In this study, five specimens of O. zagrosensis were collected from the Choman River in 2015. To examine the osteological characteristics the specimens were cleaned, stained, and photographed. The results of this study revealed that O. zagrosensis have many numerous common osteological features with O. chomanicus. However, O. zagrosensis is distinguishable based on these features from O. chomanicus by the width of neurocranium, the shapes of sphenotic, parasphenoid, permaxilla, prepalatine, preethmoid II, symplectic, epihyal, the first and second dorsal fin pterygiophores, the number of inphrapharyngobranchial, the facets for the articulation with the heads of the hyomandibular and the shape of the bony capsule of the swim bladder.
