New Record and Comparison of Some Morphometric Characters of an Endemic Species Capoeta pestai (Pietschmann, 1933) (Pisces: Cyprinidae) Populations in Central Anatolia

Endemic species, Capoeta pestai (Pietschmann, 1933) is newly recorded from the Ibrala Stream, Yesildere location , in endorheic basin of the Central Anatolia. The known distribution of this species in Anatolia previously limited to the Lake Beysehir and Egirdir Basin systems and the river Melendiz in this area. The taxonomic characters of C. pestai population in the Ibrala Stream was discussed with its other populations living in this endorheic basin. One-way analysis of variance (ANOVA) was applied to identify whether there were any statistically significant differences among the populations. Based on our results, there is a wide variation among the populations in terms of the number of scales on the line lateral, the number of 1st gill raker and some measurement taxonomic characters. In evaluating these findings, C. mauricii which described as a new species from Lake Beysehir is the synonym to C. pestai.
