Opisthoproctidae (Barreleyes or spookfishes)
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).
Body shape (shape guide): short and / or deep; Cross section: other (see remarks).
