Abstract

Anatolichthys marassantensis widely distributed in Kızılırmak drainage, and few records also available from Yeşilırmak drainage. However, the existing literature has not provided a morphological comparison between Kızılırmak and Yeşilırmak populations in a systematic approach. The present study examines, for the first time, the morphology/morphometry of A. marassantensis from both of the drainages based on additional material from Simenlik-Akgöl Lagoon Lake in Yeşilırmak drainage and published data (type materials) from Kızılırmak River. A total of 40 specimens from Simenlik-Akgöl Lagoon were compared for morphometric and morphological characters with the type measurements. According to the results of this study, morphological characters largely overlapped between selected populations of Yeşilırmak and Kızılırmak Rivers. The results obtained from this study clearly demonstrate the presence of A. marassantensis in a new location in the Yeşilırmak drainage with consistent morphological data.
