Comments. The identity of the specimen recorded by Ahmadi et al. (2012) should be confirmed as H. fluviatilis is easily confused with species like H. heydeni or H. ruficollis . H. fluviatilis lives among vegetation in streams, rivers, but also in lakes with sandy or stony bottom. Attracted to light ( Vondel 1997).
