Parmellops perspicuus, also known as the transparent semislug, is a species of semislug that is endemic to Australia's Lord Howe Island in the Tasman Sea. [1] [2]
The shell of the mature animal is reduced, plate-like and only faintly visible, 0.5 mm in height, with a diameter of 11.7 mm, reddish in colour. The animal is white with a grey tail, the shell clearly visible through the lappets. [1]
The semislug is only found on the summit of Mount Gower, crawling on palm leaves and trunks at night and after rain. [1]
