Euastacus neohirsutus Riek 1956

Keith A. Crandall
Containing group: Euastacus

Types

Holotype, Australian Museum, Sydney P34088 (male); allotype, Australian Museum, Sydney P34089 (female); paratypes, Australian Museum, Sydney P13039 (4 male, 8 female).

Type Locality

New South Wales, 20 miles west of Dorrigo.

Distribution

The species ranges from the coastal mountains 20 km north-west of Coffs Harbour, south and west through the Dorrigo region to New England National Park and Mount Killiekrankie area, a distance along the north-east to south-west axis of approximately 65 km. Mair river systems are the Orara and Nymboida Rivers to the north (Clarence River drainage) and the Bellingen and Nambucca Rivers flowing east.

Habitat

In the east of its range, E. neohirsutus is found in generally small, very cool creeks fringed by rainforest and frequently with sclerophyll forest on the higher, more exposed ridges. Altitudes range from 480 m to 710 m a.s.l. Two specimens (AM P34007) were collected from a tributary of the Bellingen River at only 70 m a.s.l. The stream was cool and lined with rainforest. This may indicate movement of the species downstream during a prolonged drought. In the west of its range on the Dorrigo Plateau at altitudes between 1070 m and 1250 m a.s.l., the species occurs in streams in areas largely cleared for agriculture, bearing at most a sparse border of eucalyptus, wattles, and raspberry along the creek banks.

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.
