Odonata of the Köyceğiz-Dalyan Nature Reserve area in southwestern Turkey, with Lindenia tetraphylla (Vander L.), new to the Turkish fauna (Anisoptera: Gomphidae)

The kdycegiz-Dalyan region is an important wetland zone in SE Turkey. It is legally protected since 1988. From the hydrobiological point of view, the importance of this area is mainly due to the occurrence of a wide variety of aquatic habitats, supporting a number of valuable biotic communities. The centre of the system is the ectogenic, krenogenic and meromictic Lake of Köycegiz, with the Dalyan Channel System between the lake and the Mediterranean Sea. Also included are 3 mesohaline lakes, connected with the Köycegiz Lake and with the Dalyan Channel, as well as several streams, discharging into the Lake, and the small Iztuzu Lake, situated close to the shore line and characterized by fluctuations in its salinity. For an account of the complex aquatic ecosystem, reference is made to e.g. N. KAZANCI et al. (1992, Zoo/. Middle East6\ 109-126), where the bibliography is also listed. The insect fauna of the region is still largely unexplored.
