In earlier literature, only Acanthonotozomella Schellenberg, 1926 , Acanthonotozomoides Schellenberg, 1931 and the extralimital Amatiguakius Coleman & J.L. Barnard, 1991 were included in the Acanthonotozomellidae ( Coleman 2007) . Actinacanthus Stebbing, 1888 , which is traditionally included in the Epimeriidae (e.g., Coleman & J.L. Barnard 1991a; Coleman 2007; De Broyer et al. 2007) is herein transferred to the Acanthonotozomellidae . The entire telson and the large ventrolateral processes on the lower part of the pereionites are characters, which are typical of the Acanthonotozomellidae .
