Abstract
More than one hundred species of Hydraena Kugelann, 1794 have been recorded from Turkey so far; more than 70 of these are known only from Turkey (see Jäch & Díaz 2001, Jäch 2004, Jäch & Kasapoğlu 2006). Many of these species are very rare and restricted to very small areas. Despite considerable collecting efforts in recent decades in northern Turkey, both of the two new species described below were collected from just a single locality in 2001 or 2005.
