In this study 19 specimens belonging to the family Cixiidae were examined that were collected from Bolkar Mountains in 2005-2007; nine species were identified. Two species are added to the list of previously known species from the region, of which one of them is a new record for the Turkish fauna. Existing species distributions have been extended. The number of Tachycixius species known from Turkey was increased to 6 with Tachycixius cypricus Dlabola, 1974. An identification key is given for these six Tachycixius species.
