Type species: Paramaretia multituberculata Mrtsn.

The genus has already been reported from New Zealand on the basis of the type species (Fell, 1958). The second, and only other known species has, however, been taken on a number of occasions from southern New Zealand; it has not hitherto been reported as the poor quality of the material, together with the lack of detailed information on variation limits in the Australian specimens, made it difficult to decide whether or not the New Zealand material is identical with that from Australia. Other specimens now available suggest that no real differences exist between the New Zealand and Australian representatives of the genus, and that therefore all local specimens are to be referred to one or other of the described Australian species. They may be separated by the following key:
