A1 not quite so long as the cephalothorax. The inner ramus of A2 about twice as long as the outer and extends back half way to the posterior edge of the cephalothorax ; the larger plumose bristles are iridescent. Cephalothorax length = 4.3 mm. Body coloration transparent, except the digestive tract filled with light yellowish material.

Recorded quite often at depths between 100 and 500 m, also deeper and occasionally shallower (Matthews, 1972). Sargasso Sea: 0-1500 m (Deevey & Brooks, 1977, Station "S").
For Esterly (1913, p.188) while this specimen was taken in the same haul with Augaptilus californicus [= Eaugaptilus filigerus], there is no other reason, so far as I can see, for considering the two as male and female of the same species.
Rose (1937) points to some apparent differences between Atlantic and Mediterranean specimens (geographical races ?).
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 1520.
