Conservation Status
Extinct (Régnier et al., 2009; Cowie et al., 2017; MolluscaBase eds., 2021)
The original scientific desription (Ponder & Avern, 2000) simply states that the species is probably recently extinct. It's extinction probably occurred in the early part of last century (i.e. c.1900-1930) as the result of the drainage of its swamp habitat.
