Hungerfordia (gastropod)

Hungerfordia is a genus of small land snails with an operculum, a terrestrial gastropod mollusk in the family Diplommatinidae endemic to the Republic of Palau. Many of the members of this genus inhabit limestone cliffs or rubble, especially in the Rock Islands (Chelbacheb) in Airai, Koror, and Peleliu states. As of 2022, there are 41 described species in this genus. A series of revisions in 2013 - 2015 described several new species, as well as transferring Palauan members of the genus Diplommatina or Palaina (including Palau endemics Diplommatina alata, D. aurea, D. crassilabris, D. gibboni, D. inflatula, D. lamellata, D. lutea, D. pyramis, and D. ringens ) into Hungerfordia.
