Araneomorph spiders from the southern Carnarvon Basin, Western Australia: a consideration of regional biogeographic relationships

WA Museum Records and Supplements | Updated 7 years ago

ABSTRACT – A survey of the ground-dwelling araneomorph spider assemblages of the Southern Carnarvon Basin revealed a total of 33 families. Apart from the Gnaphosidae and Zodariidae which were not analysed due to timeconstraints, we recognized a total of 285 species placed in 146 genera. Very few taxa could be assigned to existing genera or species, reflecting poor taxonomic knowledge of many groups of spiders. Patterns in species composition across the study area were correlated with rainfall gradients, and a discrete claypan fauna was detected. Vicariance events seem to explain part of the patterning evident. However, strongly localised patterns in species composition were also evident.
