Subfamily Diplocrininae Roux, 1981

Remarks. Teliocrinus ojii (Roux et al., 2009) is the only known undisputed fossil Diplocrininae with its crown preserved found at base of the Middle Miocene in Japan (Oji 1990). The Diplocrininae are mainly distinguished by the substantial reduction in number of brachials per brachitaxis and distal stalk symplexies with petaloid zones that remain open (David et al. 2006). This last character being paedomorphic, the attribution to the genus Endoxocrinus based only on columnals and pluricolumnals remains in open taxonomy because it is only a parsimonious hypothesis, which remains to be confirmed by the discovery of brachials or proximal arm fragments.
