The Valvata species of Turkey with a description of valvata kebapcii n. sp. (Mollusca: Valvatidae)

Abstract

The family Valvatidae Gray 1840 has a widespread distribution in the Holarctic. To date, four species of the genus Valvata have been reported from Turkey: V. cristata O.F. Müller 1774, V. piscinalis (O.F. Müller 1774), V. saulcyi Bourguignat 1853 and V. macrostoma Mörch 1864. This study is based on recently collected materials from the comprehensive field survey at Biga Peninsula streams, northwestern Anatolia, between 2009 and 2011. Additional materials were also examined from Cire Brook, Isparta, southwestern Anatolia, Turkey. Valvata kebapcii sp. n. is described here as new for science. Further research is required in order to reveal exact ranges of dispersal of the new Valvata species in Turkey.
