Emended diagnosis
A subspecies of E. (D.) alternicirrus with 12–32 arms (mode 20), up to 15.3 cm long (mean 10.7 cm); proximal brachitaxes contiguous; arm branching frequently endotomous; number of internodals per mature noditaxis 5–10 (mode 5, usually more than 50%); stalk length variable, up to 14 cm (mean 8.7 cm); proximalmost diameter rarely more than 5.8 mm (mean 4.8 mm); nodals bearing 1–5 cirri, usually 2 or 3 cirri alternately, those at one node corresponding to the place without cirri at the node immediately following or preceding; length of cirrals 1.4–2 mm (mean 1.7 mm).
Occurrence
Central Pacific (Tahiti, Hawaii), western Pacific from Kermadec Islands and New Caledonia (David 1998) to Taiwan ( Améziane et al. 2005) and Japan ( Kogo 1998), at depths from 625 m to 1476 m.
