Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); elongatus: Named in reference to its elongate terminal bulb as well as fact that this species has the relatively longest barbel among known species of Dinematochirus (Ref. 45801).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 370 m (Ref. 45801). Deep-water
Eastern Central Pacific: near Hawaii and two stations to the west.

Morphology | Morphometrics
BL greater than 20% SL; barbel with five similar branches apparently arising together from main stem (lateral pair actually arising from bases of medio-lateral pair); stem solidly pigmented, pigment extending onto dorsal side of terminal bulb; bulb elongate, only slightly thicker than stem, with an unpigmented tip usually directed dorsad; terminal filament absent or single and minute, arising from ventral side of bulb tip (Ref. 45801).
Epi- and mesopelagic (Ref. 58302).
