New South Wales, Australia.
Sister to P. occidentalis, and these two are sister to P. olivaceus, based on recent phylogenetic study#R. Formerly considered conspecific with P. occidentalis and sometimes not even separated subspecifically#R; the two were often isolated in monotypic Sphenostoma. They are very similar but differ markedly in vocalizations#R, present species having a song phrase consisting of fewer notes (ns) but a chirruping note much longer than any note of occidentalis (ns), and with a far higher frequency range (4) and with maximum frequency and total frequency range higher (score 3)#R; moreover, paler-plumaged (1); shorter-tailed with more white on tail tips (1); bill more finch-like (1); habitat chenopod and low acacia shrubberies vs mulga and taller acacia scrub (1); and ranges essentially parapatric (3)#R. Monotypic.
