(Kahoʻolawe) Pleuropoma laciniosa kahoolawensis: This terrestrial species belongs to the family Helicinidae, a group more closely related to marine snails than to other land snails. There is only one species and one subspecies known to be endemic to Kaho‘olawe. Unfortunately, this species is currently considered as extinct. Although there have been no recent surveys on this island, our hope is that one of these species is still living.
