Benekli Akdeniz sirazi * / Mediterranean scraper*. Conservation. Least Concern (LC). Material examined. FFR 01885 St. 33., - FFR 01955 St. 39., - FFR 01878 St. 57., - FFR 01883 St. 59., - FFR 01952 St. 59., - FSJF 2968 St. 71., - FSJF 2456 St. 74. Distribution in the area. Ceyhan River drainages and streams Cakitsuyu-I , Uecuergesuyu-I (Seyhan River) in Turkey. Taxonomic note. Erk'akan and Oezdemir (2011) and Oezdemir (2013) emphasised that Capoeta turani (Seyhan) and C. erhani (Ceyhan) are synonyms of C. barroisi (Orontes); even Oezdemir (2013) claimed that C. barroisi is a synonym of C. trutta (Tigris-Euphrates). Recent molecular ( Levin et al. 2012 ; Bektaş et al. 2017 ; 2019 ) and morphological ( Kaya 2019 ) data showed that C. erhani , C. barroisi and C. trutta are valid species, although they suggest that C. turani may be the synonym of C. turani . A detailed morphological examination is needed to clarify the taxonomic status of C. turani .
