Testudinidae Land tortoises of overall Turkey were studied during 2002-2006. Based on the most recent morphological classification of genus Testudo; T. g. ibera, T. g. anamurensis, T. g. terrestris, T. g. antakyensis, T. g. armeniaca and Testudo perses occur in Turkey. However, molecular studies showed that some of these taxa are not valid and in fact conspecific. We, here, tested the morphological difference among previously described molecular clades. With this aim, 38 morphometric measurements were taken from a total of 441 (221♂ and 220♀) samples. The measurements were standardized with straight carapace length then clades were compared with discriminant function analysis. For males, a total of 77% of among group variation was explained by the first canonical variate, which provides discrimination between armeniaca and other two populations (ibera and terrestris).The remaining 33% was explained by the second variate which separated ibera and terrestris. 14 of the 95 ibera females were misclassified into terrestris while 12 of the 86 terrestris were misclassified into ibera. For males, a total of 65% among group variation was explained by the first canonical variate which provides discrimination between armeniaca and other two populations (ibera and terrestris). The remaining 35% was explained by the second variate which separated ibera and terrestris. 10 of the 104 ibera females were misclassified into terrestris while 4 of the 78 terrestris were misclassified into ibera.
