2153 samples from 113 localities were collected and evaluated from shallow areas of the variaus running water and decaying organic matter between July-September 2009 and June- October 2010 to determine Hydrophilidae (Polyphaga: Coleoptera) fauna of Bitlis and Muş which are located in Van Lake Basin.At the end of the identification of these specimens, 38 taxa (37 species and 1 subspecies) have been determined in all which of them belonging to family of Hydrophilidae.
