Habeastrum

Habeastrum is a genus of minute diplommatinid pulmonate gastropods, endemic to limestone caves in Mato [Grosso do Sul], Brazil. It is represented by two sympatric species, Habeastrum omphalium and Habeastrum parafusum.
This genus has thus far been recorded only from dry material at the type locality of Gruta Pitangueiras, Bonito, [Mato Grosso do Sul|Bonito], Mato Grosso do Sul, Brazil.
The genus name Habeastrum is derived from the Brazilian diplommatinid genus Habeas, subjected to a diminutive Latin suffix, as a reference to the comparative dimensions of the new genus.
