The genus Phyllodiaptomus Kiefer, 1936 is reported from Turkey for the first time. Phyllodiaptomus sp. collected from the Batman Dam Reservoir in Southeastern Turkey was observed only between May and November 2008. The female and male specimens are illustrated in detail. Phyllodiaptomus sp. is closely related to P. blanci (Guerne & Richard) and P. irakiensis Khalaf, from which it differs in several characteristics that are discussed. The present new record extends the known distribution of the genus Phyllodiaptomus to Turkey being a natural bridge between Europe and Asia.
