Engaeus mallacoota Horwitz 1990

Mallacoota Burrowing Crayfish

Keith A. Crandall
Containing group: Engaeus

Types

Holotype, Museum of Victoria, Melbourne J14712 (intersexed reproductively active female); allotype, Museum of Victoria Museum, Melbourne J14713 (intersexed); paratypes, Museum of Victoria, Melbourne J14714 (intersexed reproductively active female), Tasmanian Museum and Art Gallery, Hobart G3214 (intersexed reproductively active female).

Type Locality

Double Creek along Nature Trail, in Croajingolong National Park, on Genoa-Mallacoota Road, east Victoria.

Distribution

The known distribution of this species is confined to two sites on the western region of Mallacoota Inlet, near the Victoria-New South Wales border.

Habitat

The type locality consisted of a creek 1-2 m wide with steep and clear banks (free of vegetation) of predominantly silty and sandy soil in warm temperate rainforest. The burrows were located by openings which were always capped with large pelleted chimneys on the bank of the creek. These burrows descended into the bank at an oblique angle and were very complex in structure, branching frequently and very deep; the burrow was filled with water at the level of the creek but no connections to the creek were found (type 2 burrows). The complexity of the burrow structure coupled with the sandy, shifting soils made successful collections of animals very difficult despite their apparent abundance.

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.
