Rem.: Epipelagic. 0-526 m ((mainly 0-97 m) at Station N-1 (SW Bösö, E middle Japan) from Furuhashi (1966 a).
Sewell (1947, p.284, Male) notes: The proportional lengths of the various segments of the body (cephalon to caudal rami) as 343 : 99 : 55 : 96 : 24 :219 : 72 : 90 = 1000. The cephalon and 1 st pediger segment fused (but in stained specimens a darkly stained line, marking the line of fusion, can be seen), 3rd and 4th fused. Genital segment consists of a large oval region and a very short posterior cylindrical portion, there is a small hook anteriorly on the ventral aspect, the genital aperture is armed with a delicate seta, on the inner side of which is a small triangular tooth. A1 6-segmented, having the proportional lengths of 20, 16, 16, 25, 12, 11. In A2 the two basal spines the shorter, arising from the base of the 3rd segment, reaches to the spine on the anterior margin of the 3rd segment; the longer , arising from the 2nd segment, reaches well beyond the tip of the shorter; the shorter claw, arising from the proximal joint of the end region, is long and slender; the long distal claw reaches well beyond the base of the 2nd basal segment.
According to Kang (1990, p.54): Tanaka (1957) and Chen & al. (1974) reported that the length of the caudal rami of female was 4 times and 3.5 times its width respectively.
For Boxshall & Halsey (2004, p.491) the subgenus (Dahl, 1912) is considered as full generic status pending phylogenetic revision of the whole family at the generic level.
