Original name: Pseudotricula auriforma Ponder, Clark, Eberhard & Studdert 2005. Ponder, W.F., Clark, S.A., Eberhard, S. & Studdert, J.B. (2005). A radiation of hydrobiid snails in the caves and streams at Precipitous Bluff, southwest Tasmania, Australia (Mollusca: Caenogastropoda: Rissooidea: Hydrobiidae s.l.). Zootaxa 1074: 1-66. 

Type locality: Damper Cave, main streamway, Precipitous Bluff caves, Tasmania.

Biology and ecology

This species  lives in a cave streamway that is wider and faster flowing than any of the habitats in which P. expandolabra occurs and the substrate lacks fine sediments.This stream is wider (about 2m) and has a faster flow (estimated at 10–20L/s) than the streams in which P. expandolabra occurs.

Distribution

Known only from the main stream in Damper Cave, Precipitous Bluff caves, southern Tasmania.
