Rückenflossenstacheln (insgesamt): 11; Rückenflossenweichstrahlen (insgesamt): 14; Afterflossenstacheln 3; Afterflossenweichstrahlen: 8. Upper edge of operculum convex; posterior nostril of large adults broadly oval, its diameter about 3 times that of the anterior nostril; ventral edge of the maxilla with a step-like expansion distally. Color is uniformly grayish brown, the fins darker. Characterized further by the following: robust body, depth contained 2.7 times in SL; body width 2.25 times in the depth; head length 2.4 times in SL; slightly convex interorbital area, width 4.4 times in HL; upper edge of operculum convex; large adults with broadly oval posterior nostrils, diameter about 3 times that of anterior nostril; step-like expansion on ventral edge of maxilla; 3 rows of teeth on midlateral part of lower jaw; inner symphyseal teeth of upper jaw not enlarged (Ref. 89707).
The only known specimen was collected in a trawl from Minami-Koto Seamount, Kyushu-Palau Ridge (Ref. 89707).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00571 - 0.02419), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.5 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (71 of 100).
