Palaeosia is a monotypic moth genus in the family Erebidae erected by George Hampson in 1900. Its only species, Palaeosia bicosta, the two-ribbed arctiid or two-ribbed footman, was first described by Francis Walker in 1854. It is found in south-eastern Australia.[1]

The wingspan is about 30 mm.

The larvae feed on lichen.[2]
