Prostomium wider than long, with three antennae and two palps. Antennae and palps digitiform. Eyes absent. Tentacular cirri with broad base tapering to a fine tip, four pairs on anterior three segments (1-2-1 arrangement). First tentacular segment dorsally reduced. Everted proboscis barrel-shaped with round terminal papilla. Parapodia uniramous. Chaetae present from segment 2. Dorsal cirri lanceolate, ventral cirri conical, both approximately as long as the neuropodia. Colour in ethanol pale yellow. Remarks. This specimen closely resembles Eumida angolensis Boeggemann , 2009, described from the Angola Basin at depths of 3950-5443 m. Alalykina (2018) reports the presence of Eumida cf. angolensis in the Sea of Okhotsk at 1676-3366 m, which would expand its range to the Pacific Ocean if confirmed. Unfortunately, no descriptions were provided for these specimens that would allow comparisons with the Australian sample. We currently consider this as a different species due to the distance from the type locality and some observed morphological differences such as having 18 instead of 16 terminal proboscideal papilla and bearing more neurochaetae per fascicle.
