+ + +© 2018 Academia Sinica, Taiwan + + +Genetic analysis + + +Of the 582 bp aligned for COI sequences, 95 were variable and 78 were parsimony-informative sites.

A third clade was identified as + +C. canariensis + +group (BP = 99), and finally a clade formed by a unique sequence was identified as + +Chtenopteryx + +sp.

Arms IV with 2 series of zig-zag shaped suckers. Tentacular clubs with 6 series of suckers in the proximal part, 16- 18 sucker series in the central part of clubs, and 6-8 series of suckers in the distal part. Visceral photophore lacking.
