Fig. 51 Diagnosis. Males differ from those of Miturgopelma harveyi sp. nov. in the smaller median apophysis with a basal lobe, and the RTA being deeply bifid dorsally. Female unknown. Etymology. The species epithet is a patronym in honour of Dr Michael Rix, in recognition for the many Western Australian species he has described. Type Material.
