Members of the genus
were approximately the size of a dingo or other medium-sized dog, and possibly
reaching the size of a small leopard.
This species comes from
the Alcoota Local Fauna of the Northern Territory. It was slightly
larger in size than W. oldfieldi and W. vanderleueri (see
below). The sole representative fossil of this species (a fragmentary
maxilla) was found in 1974 in the Miocene Waite Formation (Alcoota Local
Fauna) by Dr. Michael Archer.
The maxillary fragment
shown at right is the holotype (the single specimen designated by an author
as the type of a species) of W. alcootaensis.
