when it was identified as M. microps (Ref. 87970).

Espinhos dorsais (total) : 3; Raios dorsais (total) : 15 - 16; Espinhos anais: 1; Raios anais : 7 - 8; Vértebras: 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).
