Etymology: Melamphaes: Greek, melan, -anos = black + Greek, amphi = both side (Ref. 45335); falsidicus: The species name, falsidicus (falsifying), indicates the mistakes in the species definition, when it was identified as M. microps (Ref. 87970).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 15 - 16; Anal spines: 1; Anal soft rays: 7 - 8; Vertebrae: 29. The species is characterized by the following: rakers on the first gill arch 21-23; abdominal vertebrae 11, total vertebrae 29, haemal arch of the first caudal vertebra with 2 ventrolateral oriented spurs; D III 15-16; P 14-155; seven soft rays in the ventral fin; ventral fin starts under the vertical line of the posterior margin of the pectoral fin basement or from this vertical line); anal fin starts under the last ray of the dorsal fin (Ref. 87970).

Specimens of this species were sampled by open-mouth nets at 2500-0 m depth range and by bottom trawls at 700-790 m (Ref. 87970).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00442 - 0.02595), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
