This species is both widespead and abundant in southern Victoria, occuring on both sides of the La Trobe River Valley, usually above an altitude of 100 m, in the Western and Eastern Strzelecki Ranges and in the southwestern parts of the Australian Alps. The record of a specimen from Wilsons Promontory in the Museum of Victoria has not been substantiated (in fact this area has not been well investigated for parastacid fauna).


E. hemicirratulus is the only species in the genus which exclusively occupies burrows in type 3 habitats; these are typically situated in the yellow-orange clay-dominated soils of South Gippsland, often in what was formerly dense wet sclerophyll forest dominated by the mountain ash Eucalyptus regnans. The burrows exhibit the typical characteristics of those constructed by the other species occupying this habitat, including fan-shaped chimneys and tunnels descending obliquely to chambers; these burrows are often shallow, with the chambers occasionally just below the surface of the ground (animals are most easily obtained from such burrows). Larger burrow systems containing family groups of crayfish exhibit multiple juvenile openings on the surface and greatly enlarged chambers.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
