Brachybelistis blackburnii is a moth in the family Xyloryctidae. It was described by Oswald Bertram Lower in 1892. It is found in Australia,[1] where it has been recorded from South Australia, Victoria and Western Australia.
The wingspan is about 45 mm. The forewings are yellowish-grey whitish, scantily strewn with black scales from the base to two-thirds, except along the costa. The extreme costal edge is pale yellowish and there is a moderate roundish orange spot distinctly edged with minute black scales, in the disc beyond one-third. There is a second more ovate, on the fold below the middle, and a third more suffused beyond the middle, both tending to be suffusedly edged with minute black scales. The hindwings are grey-whitish, more ochreous-tinged towards base.[2]
