Rhytididae is a
This family has two subfamilies:
- Chlamydephorinae Cockerell, 1935 (1903)
- Rhytidinae Pilsbry, 1893
Anatomy
In this family, the number of
haploid chromosomes lies between 26 and 35 (according to the values in this table).[2]
Distribution
This family of land snails has a range which extends from South Africa to New Guinea, some of the higher South Pacific islands, New Zealand[3] and Australia.
The New Zealand genera include Delos, Delouagapia, Paryphanta, Powelliphanta, Rhytida, Wainuia and Schizoglossa. These, however, probably do not form a
monophyletic group, as indicated by their differences in their size, shape and radular morphology.[4]
