Biology, affinity and description of an anusual aquatic new genus and species of Isotomidae (Collembola) from high altitude lakes in Tasmania
A new species of Isotomidae (Collembola) was collected from submerged stones on the edge of nine lakes on Tasmania's Central Highland Plateau. Because it did not comply fully with the characters of any existing genus, a new genus, Chionobora gen. n. is erected for it here. An Antarctic species,...
