Great Basin Naturalist


A new genus, Aplanusiella (type-species, Aplanusiella utahensis, n. sp.) and two new species, A. utahensis and A. californiensis, are described and illustrated. The two species are allopatric and coexist on the same host genus (Atriplex) with members of a closely allied leafhopper genus, Aplanus. Notes on distribution of hosts and leafhoppers as well as leafhopper intergenetic relationships are also given.
