Etymology: Monacoa: The name constructed by Whitley was without any etymological reason; however, it is likely referring to the state of Monaco, in which the research expedition that sampled the two syntypes originated; niger: Name from Latin 'niger' for 'black'; referring to the black streak of pigmentation present on the sole.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
This species is distinguished by having black pigmentation along the entire sole and possibly have a darker or more blackish body color compared to congeners (scale pockets are darker); and the black streak on the sole possibly consists of distinct patches posteriorly . The holotype is slightly damaged on the sole and variation of its pigmentation pattern must be assessed with future fresh material (Ref. 111070).
Body shape (shape guide): short and / or deep; Cross section: other (see remarks).
