Janusya adusta
Janusya adusta is a species of sea sponge in the family Clathrinidae found in Australia. The species was first described as Clathrina adusta by Gert Wörheide & John [Hooper (marine biologist)|John Hooper] in 1999, and was assigned to the genus, Arthuria, in 2016 by Oliver Voigt & Wörheide. However, the name Arthuria had already been used and hence the genus name was changed to Arturia. It was subsequently moved again to the genus Janusya.
