Holotype, Australian Museum, Sydney P15299 (male); paratypes, Australian Museum, Sydney P34095 (8 male, 4 female).

Type Localilty

New South Wales, Snowy River Bridge, Mount Kosciusko.


The species is known from the high alpine and semi-alpine country of the Snowy Mountains, particularly around Mount Kosciusko, north to the Kiandra and Yarrangobilly regions, south-west of the Australian Capital Territory, a north-south distance of 100 km. Major drainage is via tributaries of the Snowy, Murray and Murrumbidgee Rivers.


E. rieki was collected at altitudes above 560 m a.s.l., and usually above 1000 m (to 1520 m). From museum records, it is likely that the species extends into the highest areas of the Koscuisko region. Vegetation along the sampled creeks was dry sclerophyll (largely snow gums at high altitudes) with heath or tussock grass. Shade on the streams was moderate to poor and water was clear with very little algal growth. Stream beds were largely gravel with some loose rocks, bedrock in places. The species was collected from under rocks and from burrows in the stream beds. Most of the sampled streams are covered in snow or ice in the winter. Presumably the species is then dormant or semi-dormant in its burrows.

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.
