Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); bibulboides: Named for resembling bibulbosus in having a simple filament.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 1100 m (Ref. 11333). Deep-water
Eastern Central Pacific: off Oahu, Hawaiian Islands.

Max length : 14.5 cm SL male/unsexed; (Ref. 11333)
Morphology | Morphometrics
soft rays: 40;
Vertebrae: 68. Two terminal bulbs separated by a short interspace (0.5-1.8 times length of distal bulb in larger specimens; as much as 2.4 times in smaller ones). Barbel 39-62% SL, rarely slightly less. Terminal filament short, without branches. Distal bulb 0.5-1 times length of proximal bulb in large specimens (up to 1.8 times in smaller ones). Axis of stem pigmented, variably light to dark. External chevron-shaped or striated areas on stem seldom pigmented in specimens larger than 8 cm. Paired dorsal spots between occiput and dorsal-fin origin usually 8, sometimes 7 or 9 (Ref. 11333).
Mesopelagic at 75-960 m (Ref. 58302).
