|Taxonomic Notes:||Knipowitschia is sometimes considered a synonym of Pomatoschistus. This is based on the study of K. caucasica only and awaiting the study of other species, Kottelat and Freyhoff (2007) retain the genus as distinct. The variability (morphological and ecological) reported for K. caucasica suggests that this is a complex of several species.|
