Lyropupa rhabdota ssp. pluris Cooke & Pilsbry

Many-striped Lyropupa Snail (Lyropupa rhabdota ssp. pluris)

This taxon was described in 1920; it is known from Kaunakakai at the central southern coast of Moloka’i, Hawaiian Islands; they were found quite abundantly among dead leaves in humid, shady places.

The shells reach sizes of about 0.22 to 0.24 cm in height; they differ from the nominate race in being shorter and having rather weaker, less regular spiral striae. [1]

According to a study from the year 2018, all Hawaiian species of this genus are now sadly extinct. [2]
