Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335).
Eponymy: Harry Payne Bingham (1887–1955) of Cleveland, Ohio was an American philanthropist and businessman with an interest in natural history. [...] (Ref. 128868), visit book page.

Long, tapering, protrusible snout. Short chin barbel 18.3% SL, with a single terminal bulb; barbel with 2-3 branches arising from stem. Branches with several to many filaments which often end in bulblets. Terminal bulb twice as long as it is wide and has 1 prominent filament and several minor filaments. Two tightly bound pectoral rays (Ref. 37039).
Body shape (shape guide): elongated.
Maximum length 101 mm SL refers to immature male. Replace with better estimate once available.

Estimates based on models
Preferred temperature (Ref.
123201): 6.3 - 16.2, mean 11.4 °C (based on 110 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 4.2 ±0.8 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
