Etymology: Eupogonesthes: Greek, eu = good + Greek, pogon = beard + Greek, esthes, -etos = cloth (Ref. 45335); xenicus: From the unique structure of the chin barbel and the intermediate position of the species between the genera Borostomias and Astronesthes ('xenos' = foreign, exotic).

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10; Anal soft rays: 16; Vertebrae: 54. Body brown black; paired caudal fins not pigmented; dorsal and anal fins pigmented; adipose fin brilliant black. Chin barbel long, almost twice as long as the head, tapering to the end; with 2 glandular bulbs, the anterior one appearing as spindle-shaped expansion of the shaft which begins just behind the articulation with the chin and occupies nearly 1/3 of the length of the barbel; posterior bulb like a terminal proboscis of the barbel (Ref. 41472).

Found on the continental slope (Ref. 75154).

Estimates based on models

Preferred temperature (Ref. 123201): 10.3 - 14.6, mean 11.8 °C (based on 21 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00417 (0.00171 - 0.01014), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 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. 59153): Low vulnerability (10 of 100).
