The pattern of taxonomic relationship and morphological divergence of three copepod species Thermocyclops crassus, T. dybowskii and T. vermifer collected from three different localities in Mediterranean region of Turkey were investigated. A multivariate ANOVA using morphometric characters revealed highly significant intersample variation for most of the characters between species. In discriminant function analyses, the first discriminant function accounted for 65% and the second accounted for 35% of the between-group variability, showing clear between-species differentiation. Component loadings of discriminating variables showed that thorax segments of cephalothorax played an important role to discriminate Thermocyclops species. The Neighbour-joining analysis produced two main clustering, T. vermifer was closest taxa to T. dybowskii being the sister group to the T. crassus which was the most divergent in this group. In the correct assignment of individuals into their original sample, the proportion of correctly classified T. crassus to their original group was highest (100%), showing a clear separation from the other species. Key words: morphologic divergence, systematic, copepod, Thermocyclops, freshwater.
