The freshwater epigeous asellids of venezia giulia northeastern italy


, : The freshwater epigeous asellids of venezia giulia northeastern italy. Fragmenta Entomologica 18(1): 19-32

The Asellids collected in epigeous freshwater environments of Venezia Giulia (Northeastern Italy) are: Asellus (Asellus) aquaticus aquaticus L.) sensu Racovitza, 1919, living in running waters with moderate or strong current; Proasellus coxalis tergestinus n.ssp., living in reservoirs with rain water; Proasellus istrianus (Stammer, 1932), living in some sources on arenaceous flysch. Proasellus coxalis tergestinus n.ssp., is described; it is the first discovery of Proasellus coxalis (Dollfus) in northeastern Italy; its phylogenetic and zoogeographic role is discussed. The description of Proasellus istrianus (Stammer) is made, based on a lot of specimens, and the taxonomic role of this species is discussed. The species seems to be present in Italy only in the Province of Trieste.
