Rem.:

Meso-bathypelagic.
Sampling depth (Antarct.) : 0-1000-3000 m.
For Park (1993, p.41) the species is very similar to E. magnus (Wolfenden, 1904) but can be distinguished from it by the large body, relative size of the Md palp, shape of the Md palp, and setation of the A2, Md, Mx1 and Mx2.
First occurrence in Indonesia waters by Matsuura & al. (2010).
