John Gould described the striated thornbill in 1838, giving it the common name of striated acanthiza. Alternative common names include striped-crowned thornbill or tit-warbler, striated tit-warbler or tit, and green thornbill. The striated thornbill still bears its original name. A 2017 genetic study using both mitochondrial and nuclear DNA found that the ancestor of the striated thornbill diverged from that of the
yellow thornbill around 6 million years ago. Four subspecies are recognised. •
A. lineata alberti is found in southeast Queensland and is paler and more yellowish overall than the nominate subspecies. It has a bright orange-brown cap with prominent white streaks, and a yellow-olive back. There is a broad zone of intermediate birds stretching from Tenterfield south to Port Macquarie on the coast and Tamworth inland. •
A. lineata lineata is found across New South Wales and Victoria, with a zone between the Grampians and Warrnambool, and the South Australian border where intermediate forms between this and
clelandii are found. •
A. lineata clelandii is smaller and paler than the nominate subspecies, though has a more greyish back. It is found in southeastern South Australia to Adelaide. •
A. lineata whitei is smaller and darker than the nominate subspecies, with an overall greyish cast. It is found on Kangaroo Island. ==Description==
