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.; griseus: Name from Latin 'griseus' for 'grey'; referring to the uniform greyish anterior part of the sole lacking distinct patterns of pigmentation..

Description synthétique Clés d'identification | Morphologie | Morphométrie

This species is distinguished by the following characters: a greyish anterior part of the sole, abruptly changing just in front of the pelvic fins, to a dense pigmented posterior part; two adult specimens show in addition, a relatively weak irregular large blotch just in front of the change in pigmentation, centered approximately below the anterior part of the dorsal fin in the vertical plane; scale pockets possibly relatively light (Ref. 111070).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02188 (0.00844 - 0.05670), b=2.98 (2.75 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.1 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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