A molecular and morphological review of the asterinid, Patiriella gunnii (Gray) (Echinodermata: Asteroidea)

The six–rayed species of the asterinid genus Patiriella Verrill from the rocky shallows of southern Australia are reviewed. Based on molecular and morphological evidence, it is judged that Patiriella brevispina H.L. Clark is a junior synonym of Patiriella gunnii (Gray). Three new species are described: Patiriella medius sp. nov., Patiriella occidens sp. nov. and Patiriella oriens sp. nov. A key to the four species of Patiriella is provided.
