Subfamily Isselicrininae Klikushin, 1977

Remark: Klikushin (1977, 1992) included in this subfamily the extinct genera Austinocrinus, Doreckicrinus, Isselicrinus (= Buchicrinus), and Praeisselicrinus, the latter is known from pluricolumnals only. Simms (1988) raised it to family rank and also referred the extant genera Cenocrinus, Endoxocrinus, Annacrinus, Diplocrinus, Metacrinus, and Saracrinus to it. Here, we maintain Isselicrininae as a subfamily rank and of extant genera include only Panglaocrinus gen. nov. (see Discussion below).
