Type Locality

New South Wales, Tianjara Creek above Falls, tributary Shoalhaven, near Tianjara.


The species is known only from Tianjara Creek, above Tianjara Falls, a tributary of the Shoalhaven River near the southern boundary of Morton National Park, 30 km west of Jervis Bay, New South Wales. It is possible that the species extends north-west through the unsampled wilderness core of Morton National Park or south to the headwaters of the Clyde River.


The type locality is a small stream with sandstone bedrock, the banks lined by dry sclerophyll and heath forest. Though apparently typical of other creeks in the area, only this site revealed populations of E. guwinus. The site was open and rather poorly shaded but crayfish were more common under rocks in the shade of a bridge.

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.
