Diagnosis: Oxynoemacheilus ciceki sp. n. is distinguished from the other species of Oxynoemacheilus in the Kızılırmak basin by a combination of characters, none of them unique. Oxynoemacheilus ciceki sp. n. is distinguished from O. angorae by having flank yellowish brown or pale gray with irregular spots (vs. yellowish with a mid-lateral row of horizontally elongated fused blotches), cheeks with numerous tiny spots (vs. without pigmentation), without scale (vs. scaled), shorter pelvic fin (11.3- 13.6 vs. 14.9-17.0 %SL), lower mouth width (16.0- 22.0 vs. 20.6-26.7 %HL).

Etymology: The new species is named after Prof. Dr. Erdoğan Çiçek, for his valuable contribution to the knowledge of freshwater fishes of Turkey.
