Sminthopsis youngsoni (Marsupialia: Dasyuridae), the Lesser Hairy-footed Dunnart, a new species from arid Australia.

Abstract

A new species of dunnart, Sminthopsis youngsoni, is described. It is smaller than, but most similar to the Hairy-footed Dunnart, S. hirtipes. These two species form a subgroup of arid-adapted species within Sminthopsis. The new species comes from habitats on sandy surfaces throughout arid tropical areas of Western Australia.
