This species is found near the localities for P. marginata but it differs from that species in shell morphology, most notably in being broader, with fewer whorls and a relatively larger last whorl It is somewhat similar to P. pupiformis and P. warwicki in shell shape, but both those species have a broad based penis with a straight penial duct. P. annamurrayae also resembles Beddomeia phasianella in shell outline, but is much larger.

Original name: Phrantela annamurrayae Ponder & Clark, 1993. In Ponder, W. F., Clark, G. A., Miller, A. C & Toluzzi, A. (1993). On a major radiation of freshwater snails in Tasmania and eastern Victoria - a preliminary overview of the Beddomeia group (Mollusca: Gastropoda: Hydrobiidae). Invertebrate Taxonomy, 7: 501-750.
Type locality: Small tributary of Heazlewood River, on Mt Cleveland Road, Tasmania.
Found on weed, stones, leaves and wood in stream bed. Egg capsules unknown but probably like those of an unnamed species of Phrantela; small, with single embryo, and covered in coarse sand grains. Development direct.
This species is found in a small stream near its junction with the Heazlewood River, northwest Tasmania, along with Beddomeia cf. hullii and two species of Austropyrgus.
