Two new species of the genus Munnogonium (Isopoda: Asellota: Paramunnidae) from Argentina

Two new species of paramunnid isopods from Argentina are described: Munnogonium quequensis n. sp. from Buenos Ai-res Province (Quequén) and M. diplonychia n. sp. from Patagonia (Comodoro Rivadavia, Rada Tilly and Puerto Deseado). Both species are distinguished from their congeners by having a tight...
