Remarks. A Turano-Europeo-Mediterranean species, present in all Italian regions ( Alma et al. 2009; Cianferoni 2009). Although it is a very common species in lentic and lotic waters, the first record for the Park was published only very recently ( Terzani et al. 2012). It was previously cited for this area as Hydrometra sp. ( Mazza et al. 2008a).
