Two New Hyporheic Amphipods, Bogidiella ( Bogidiella) Cyrnensis n. sp. and Bogidiella (Medigidiella?) Paolii n. sp., from Corsica

Abstract

Two new amphipod species of the family Bogidiellidae were found in the hyporheal of two small rivers on Corsica. Both new species, Bogidiella ( Bogidiella ) cyrnensis n. sp. and B. paolii n. sp. (provisionally placed in the subgenus Medigidiella , but a definitive classification will have to wait till males are found), encountered at altitudes of 135 m and 750 m, respectively, show more affinities with certain freshwater species of Sardinia than with marine species of the Mediterranean.
