Laemodonta sp. #1
|Maximum size: 6.4 mm (Severns, 2011).
species has a stout, dark-brown shell with flattened spiral cords
separated by narrow striae. There are two folds inside the outer lip and
three folds on the
columella. Kaneohe Bay shells are similar in color but have less-flattened cords that become more irregular basally.
We haven't personally seen Laemodonta
sp. #1 on Maui. However, it's been found on rocks around anchialine
pools at Cape Kinau. (Severns, 2011) It's also been found in highly
protected habitats in Kaneohe Bay, Oahu.
Taxonomic notes: It's illustrated in Severns, 2011 as Laemodonta octanfracta (with the more common species that Kay, 1979 assigns to that name listed as Laumodonta clausa). However, we haven't been able to confirm that usage with WoRMS and other sources. So, we're listing it as L.
sp. #1. It's also possible that the Cape Kinau and Kaneohe Bay animals
are different species but we've opted to lump them based on color and
form pending further work.
