The present study was conducted to identify the parasitic infections of Piscicola geometra, on three different species of Cyprinidae in two reservoirs of the Euphrates-Tigris basin, Turkey. The investigation was carried out from May to November, 2013 for Dumlu creek and from September, 2014 to April, 2015 for Goynük stream. Fourteen parasites were recorded on seven of the 94 examined fish specimens. This study is to be the first record of P. geometra parasitizing on Capoeta capoeta, Alburnus mossulensis and Cyprinion macrostomum for freshwater fish parasite fauna.

Aquatic Coleoptera fauna of the Ramsar site Sultan Sazl??? (Kayseri, Turkey) was investigated between May and October 2009. A total of 87 species were determined. Their distributions in Turkey are presented. Worldwide distributions of four newly-recorded species (Agabus lineatus Gebler, 1848, Helophorus pumilio Erichson, 1837, Helophorus redtenbacheri Kuwert, 1885 and Cercyon tristis (Illiger, 1801)) from Turkey are also given. It was established that Turkey is the southernmost limit of distribution of all the newly recorded species from Turkey.
