Plakortis fromontae is a species of marine sponge in the order Homosclerophorida, first described in 2011 by Guilherme Muricy.[1] [2] The species epithet, fromontae, honours Jane Fromont.
The holotype was collected off Rat Island, Western Australia, in the Houtman Abrolhos and the species is known only from that locality.[1]
