Abstract

Spiders from 13 widely separated populations of Misgolas hubbardi Wishart are shown to exhibit distinct phenotypic and genotypic differences in the first such study on ground dwelling spiders in Australia. Electrophoretic analysis also supports the conclusion that the syntopic and morphologically constituted M. hubbardi Wishart, M. dereki Wishart and M. robertsi (Main and Mascord) are valid species. While M. hubbardi can be reliably determined from male palpal characters, the shape of the embolic apophysis and the ventum pigmentation pattern are variable and valid diagnostic characters only for particular populations and where the locality is known. the morphological differences in M. hubbardi populations are summarised and its distribution compared to the geology of the region.
