On two paramunnid species from the Beagle Channel, Argentina (Crustacea: Isopoda: Asellota)

Austrosignum fuegiae, a new species, is fully described on the basis of specimens collected in the shallow waters of the Beagle Channel. The genus Austrosignum Hodgson, 1910 is in need of revision, and the inclusion of A. fuegiae in this genus should be considered provisional. Austrosignum fuegiae i...
