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).

Morphology | Morphometrics
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).

Bayesian length-weight: a=0.01096 (0.00451 - 0.02668), 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
