It is clear that the New Zealand Athoracophoridae have been separated from their relatives in Australia and the New Hebrides for a very long time, and the sharing of a common chromosome number shows that the group displays the same cytological conservativeness seen in most other snail groups. It is still not possible to determine whether the high chromosome number found in the Athoracophoridae has resulted from polyploidy.
