Gabbia tumida Ponder, 2003

Diagnostic features

This species is similar to the smooth-shelled species resembling G. vertiginosa (G. campicola, G. rotunda, G. kendricki, , etc.) but differs in having a smaller adult size than some of these species and from all but G. fontana, G. davisi and G. obesa in being narrowly umbilicate. Known only from a few samples of empty shells associated with limestone caves in NW Australia.

Original nameGabbia tumida Ponder, 2003. Ponder, W.F. (2003) Monograph of the Australian Bithyniidae (Caenogastropoda: Rissooidea). Zootaxa 230: 1-126.

Type locality: Ngumurra Nawaru (Claud Cave), Kimberley, Western Australia.

Biology and ecology

Empty shells of this species have only been found associated with limestone caves. However, as it has not been observed or collected alive, it is unknown whether it lives within the cave systems themselves.


This species is known from only three samples of empty shells. One, in Gregory National Park, is about 540 km distant from the others, but all are inland from the Kimberley region.
