Type Locality

New South Wales, MacLaughlin River near Nimmitabel.


The species is distributed from the Craigie area, near the New South Wales and Victorian border, north through the Nimmitabel type localities to the vicinity of Captains Flat, a distance of 160 km along the Great Divide. The range is drained by tributaries of the Snowy, Tuross Murrumbidgee and Shoalhaven Rivers.


Riek (1969) did not descripe the type locality of E. claytoni, but the MacLaughlin River near Nimmitabel is narrow with deep (>2 m) pools and shallow rocky stretches, with grass and some sclerophyll forest along the banks. Much of the area has been cleared and no specimens were found there in 1981. Elsewhere the species was collected from streams mainly in granite country with poor temperate rainforest and tree ferns along the banks, dry sclerophyll on ridges. Specimens were collected at elevations over 800 m. Crayfish holes were very common among streams in the area, including several flowing through Pinus radiata plantations. Riek (1969) recorded in some detail the burrow of E. claytoni. Two or more surface holes, sometimes plugged with mud, lead to the burrow network, with a central chamber. A burrow extends to the water table.

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.
