, and genetic sequencing confirms a sister relationship between the two taxa. The species occupies a wide range in the NT and WA, but has not been recorded from any other state thus far. Foragers have been aspirated on the crest of a small dune 30 km from Sandfire Hill, WA and from among tussock grass in seaside dunes in the town of Port Hedland, WA, but other data are lacking.
