Abbott (1968) held a very comprehensive concept of the genus Phalium, to include all the species of the subfamily Phaliinae except those included in Casmaria H.& A. Adams, 1853. Current authors (Alf, 1997; Beu, 2008) would include in Phalium only those species which have
varixes all along the
spire and have spines around the outer edge of the terminal varix as in Casmaria. Species with predominantly spiral
sculpture and with only a terminal varix without spines are currently classified in Semicassis Mörch, 1852 but often cited under Phalium.[1]
Species
According to the
World Register of Marine Species (WoRMS), the following species with valid names are included within the genus Phalium :[2]
