SUBFAMILY DIPLOCRININAE ROUX, 1981

Emended diagnosis: Pentacrinid crinoids with IBr2ax, never transverse synarthry at IBr1+2, arm synostoses or syzygies with flat to weakly concave symmorphy; through evolution brachitaxes restricted to fewer than five brachials in recent genera; stalk symplexy with inner crenularium restricted to absent, lanceolated areolas opened outwards, and relatively few crenulae (usually fewer than eight per interpetaloid zone); five cirri or fewer. Found from the Lower Cretaceous to recent times.

Included genera: Doreckicrinus Rasmussen, 1961 (from the Upper Cretaceous to the Palaeocene); Endoxocrinus Clark, 1908 (from the?Miocene to recent times, including Diplocrinus Döderlein, 1912 and Endoxocrinus Clark, 1908 as subgenera); Nielsenicrinus Rasmussen, 1961 (from the Lower Cretaceous to the Palaeocene), Teliocrinus Clark, 1909 (from the?Miocene to recent times).
