The boggomoss snail is a medium-sized snail characterised by a relatively thin, semi-transparent shell. The shell is almost flat with a slightly elevated spire and very small central depression. Shell diameter is between 21 and 26 mm, shell height is between 14 and 16 mm. Shell colour is light-brown to horn with a slight yellowish-green tinge (Queensland Department of Environment and Heritage Protection 2017). The animal is grey with a mustard coloured mantle and distinct irregular black blotches on the lung roof that are visible through the shell. The shell surface appears smooth but microscopically shows a series of covering ridglets that bear a fine elongate scale in fresh specimens (Queensland Department of Environment and Heritage Protection 2017).

Other threats to the Boggomoss Snail that are currently recognised include at the site of the smaller population; clearing of surrounding vegetation makes the Boggomosses vulnerable to drying out.
The species is subject to a number of ongoing threats changes to water flows in the Dawson River; drying out of Boggomoss habitat; fire; grazing; introduced weeds; timber collection and quarrying.
