The Recent brooding species of the genus Amphipneustes (Schizasteridae) live in the subantarctic and antarctic regions. A new brooding species, Amphipneustes davidi, differs from its congeners in three ways: the periproct, located at the ambital posterior region of the test, is conspicuous from the apical side; the posterior ambulacral avenues of the oral side are strongly directed laterally; peculiar huge bidentate pedicellariae show an unusual spatulate shape.
