Discrimination of Cobitis simplicispina Hanko, 1925 and Cobitis turcica Hanko, 1925 populations (Pisces: Ostariophysi: Cobitidae) from Turkey.
The most significant morphometric characters differentiating the specimens of Cobitis simplicispina collected from the Sakarya-Kizilirmak river basins, Cobitis turcica collected from Bagilli and not so far recognized species from Saz Lake were investigated in this work. ANOVA (Analysis of Variance) and canonical discriminant analysis were applied to 44 variables (5 meristic and 39 metric characters derived from 24 measured variables) to show the main differences between three populations. Populations from different localities appeared to be significantly different from each other both in meristic and metric characters. The following characters: standard length/head length (sl/Hc), preorbital length/longitudinal eye diameter (PrO/Oh), standard length/interorbital width (sl/io) and head length/longitudinal eye diameter (Lc/Oh) were important in distinguishing these three populations.
