Euastacus brachythorax Riek 1969

Keith A. Crandall
Containing group: Euastacus


Holotype, Australian Museum, Sydney P15716 (male); allotype, Australian Museum, Sydney P15717 (female).

Type Locality

New South Wales, Brown Mountain.


The species is known from the Brown Mountain area west of Bemboka, 25 km south along mountains to near Mount Darragh, northwest of Wyndham. A specimen from near Timbillica, a further 60 km south, indicates that the species extends to near the Victorian border, though the distribution may be patchy.


The species was collected from streams in granite country between 240 m and 1000 m a.s.l., with light temperate rainforest or tree ferns along stream banks and dry sclerophyll on ridges above. Streams were well shaded. The Timbillica specimen was presumably from a lower altitude, though the habitat was described as similar (P. Horwitz, pers. comm.).

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.
