Rem.: bathy-abyssopelagic. Known at depths from around 600 to below 1000 m (Matthews, 1972). Sampling depth (Antarct.): 0-600 m. Sargasso Sea: 500-2000 m (Deevey & Brooks, 1977, Station "S");
Vervoort points out the resemblance with H. longicornis: The specimens from the Gulf of Guinea resemble in many aspects, particularly the great length of A1, but differ 1- they are much larger; 2- the frontal part of the head has only a very slight and rounded protusion, bearing the rostral filaments. These filaments at their base are distinctly swollen; 3- the setiform spine at the outer margin of the coxa of P5 in the female is greatly lengthened; it is about twice as long as the exopodite. In the Atlantide Expedition the specimens agree perfectly with Brodsky's H. longicirrus.. For Brodsky (1967, p.364) this species resembles E. longicornis but differs in size, in the greater length of the caudal rami, and in the structure of P5.
Park (1970, p.537) believes H. setuliger Tanaka (1964) synonymous of this species.
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 2320 (as H. setuliger).

See remaks in H. paralongicirrus Park, 1970.
Mx1 after Bradford-Grieve (1999, p.941) : Exopodite of Mx1 female with 9 setae. Outer seta of P5 basipodite more than twice length of the exopodite.
