Species: 

Isotomurus maculatus Müller, 1876

Originally thought to be Isotomurus cf. palustris, this species was recently confirmed to be I. maculatus (Greenslade 2010). An introduced species, I. maculatus occurs mainly close to coastal areas on Marion Island and individuals are especially abundant in the tussock grass Acaena magellanica and on liverwort. This species is easily recognised by its mottled colour pattern and hairy body (Fjellberg 2007). Eggs are laid in batches and are initially yellow, before turning pink a day or two before hatching. Hatchlings of I. maculatus are pink in colour.
