Maxillae with field of cuspules confined to inner corner (Fig. 224); labium without cuspules. Abdomen (Figs 220, 223) broadly oval, dark grey-brown in dorsal view with tan mottling. Posterior abdomen moderately sigillate (Figs 220, 223); SP2 sclerites irregular, comma-shaped spots; SP3 sclerites subcircular with irregular margins, each surrounded by pad of unsclerotised cuticle; SP4 sclerites subcircular with irregular margins, each surrounded by chevron-like pad of unsclerotised cuticle laterally; SP5 obscured.

), the nominate member of the intermedium-clade (Fig. 25), has a relatively widespread albeit poorly defined distribution in the eastern Wheatbelt and north-western Coolgardie bioregions of south-western Western Australia (Fig. 376). Its known range extends from Bodallin north to Billiburning Rock in the eastern Wheatbelt, and east to near the Helena-Aurora Range, Mount Manning, and Koolyanobbing in the Coolgardie bioregion. Like

was formally assessed as 'priority 3' fauna; this assessment incorporated the latest taxonomic, geographic and genetic data summarised in the current study (with a number of additional records also identified subsequently). It has a known extent of occurrence of nearly 14,500 km2 [14,102 km2] (a likely underestimate due to limited survey effort), and while it

cannot be considered threatened under Criterion B, a 'priority 3' recommendation was made due to the occurrence of this species in areas prospective for mining and mineral resources. Further close assessment under both Criteria A and B is warranted in the future.
