Diagnosis. Females differ from those of T. australis sp. nov. in having a minute palpal claw, and having large spines on the cheliceral process ( Fig. 133b View FIGURE 133 ) and in the larger accessory lobe ( Fig. 133d View FIGURE 133 ) on the spermathecal head. Male unknown.

Etymology. The species epithet is in honour of the collector and scientist, Dr Peter Hudson, South Australian Museum.
