Red Catinella Snail (Catinella rubida)  

The Red Catinella Snail, which is the type species of its genus, was described in 1870.  

The species is, or rather was restricted to swampy forest areas at Wahiawa in the southern part of the island of Kaua’i, Hawaiian Islands, where it was found at elevations of about 600 m.  

The Red Catinella Snail was one of the semi-slug-like members of the Succineidae, its shells was typically flattened with the last whorl being extremely enlarged, and the life animal very likely could not pull its body fully into it.

There have been intensive field surveys in the early 2000s with the intention to find this and other succeinid species, however, without any results. [1]
