Mironov, Alexandr N. & Fujita, Toshihiko, 2021, Hirsutocrinus duplex, a New Genus and Species of Sea Lilies (Crinoidea, Comatulida, Bathycrinidae) from the Western North Pacific, Species Diversity 26 (1), pp. 101-110 : 102

Genus Hirsutocrinus n. gen

Type species. Hirsutocrinus duplex n. sp.

Included species. Hirsutocrinus duplex n. sp.

Etymology. The generic name is derived from the Latin word hirsutae (spinulated) in reference to the secundibrachials covered in small spines.

Differential diagnosis. New genus differing from other genera in the family Bathycrinidae in having knobby processes both on IBr2 and Br1+2, and distinct side plates in pinnules.

Remarks. In addition to Hirsutocrinus , the genus Monachocrinus is characterised by presence both cover and side plates. The side and cover plates in pinnules are strictly different from each other in their shape in Hirsutocrinus , and they are similar in Monachocrinus . See Table 1 and discussion below for comparison between Hirsutocrinus n. gen. and other bathycrinid genera.
