not strongly elevated dorsally (post-ocular ratio 0.21) (Fig. 7L). Chelicerae without accessory setae on anterior face of paturon. Abdomen 2.10 long, 1.41 wide; with three pairs of dorsal hump-like tubercles (HT 1-6). Internal genitalia with dense cluster of ≤ 15 variably shaped spermathecae on either side of gonopore, clusters meeting near midline of genital plate (Fig. 23F); innermost (anterior) spermathecae longest, sausage-shaped, curved antero-laterally; outermost (posterior) spermathecae bulbous; other spermathecae variably pyriform, mostly straight, directed antero-laterally.

is known only from rainforest and mesic closed forest habitats on the Barrington Tops Plateau, in the Barrington Tops National Park and Barrington Tops State Forest, New South Wales (Fig. 41). A juvenile specimen from Chichester State Forest and a single female specimen from Gloucester Tops may also belong to this species (see Remarks, below).

from the Barrington Tops Plateaux (i.e. Barrington Tops, Gloucester Tops and Chichester State Forest) seem to exhibit a larger than normal amount of morphological and molecular variation, as highlighted by the deep (~6%) COI and COII sequence divergences observed among specimens collected along the Barrington Tops Forest Road in April 2010 (Fig. 3A), and the incongruous CH/CL ratio of the single female (AMS KS102950) from Gloucester Tops relative to the only known female from Barrington Tops (WAM T112568) (see Fig. 6). It is possible that two cryptic species may occur in sympatry on the various mountains and plateaux that make up the Barrington Tops region, although the current paucity of specimens makes this difficult to ascertain. For the purposes of this revision, specimens from the northern Barrington Tops National Park (and State Forest) are recognised as conspecific with the holotype of
