Sampling depth (Antarct., sub-Antarct.): 0-1200 m.
Malgré la grande différence des tailles, Grice & Hulsemann (1967) ne doutent pas de la synonymie entre cette espèce et Augaptilus subfiligerus.
Pour Matthews (1972) et Park (1993), la forme signalée par Tanaka & Omori (1967) comme E. oblongus n’est pas synonyme de E. rectus comme l’affirment Tanaka & Omori (1974, p.252).
