member of the diverse sigillatum-clade (Fig. 25), has a restricted distribution along the eastern margin of the Dandaragan Plateau, from near New Norcia in the south, north to at least the Watheroo National Park (Fig. 374). Its distribution closely abuts the north-western extent of the range of

are similar in having strongly sigillate (sclerotised) abdomens, although morphology and molecular data can be used to convincingly separate them. Little is known of the biology of this species, other than that males have been collected (wandering in search of females or waiting in their burrows) in late autumn.
