Atrax is a genus of venomous spiders found in Australia. It is a member of the family Atracidae, the Australian funnel-web spiders. The genus was erected by Octavius Pickard-Cambridge in 1877 for the species Atrax robustus.[2]

As of January 2016, the World Spider Catalog accepted the following species:[1][2]


Phylogeography can be understood as the historical changes or occurrences that bring about a change to a specific species or organism. After extensive studies, researches have found that there are many geographical and genetic differences that have occurred due to micro habitat distributions. The assumption has been made that species of Atrax have experienced a shift in genetic structure due to the niches they inhabit. Habitats are not the only factor to this divergence, researchers also noted the climatic events, prey availability, and natural occurrence of biodiversity [3]
