Etymology: Rocio: Named for the author's wife. In Spanish, the name means morning dew, in allusion to the resplendent spots on cheek and sides of some species, R. gemmata; gemmata: Name fro Latin 'gemmata' meaning 'bejeweled', referring to the large, bright green and blue cheek and opercle spots in life; an adjective.
Eponymy: Rocío is a Spanish word for ‘morning dew’, an “image evoked by the resplendent spots on cheek and sides of some species”; Rocío is also the name of Juan Schmitter-Soto’s wife. (Ref. 128868), visit book page.

Épines dorsales (Total) : 18; Rayons mous dorsaux (Total) : 9 - 10; Épines anales: 8 - 9; Rayons mous anaux: 7 - 8. This species is characterized by the following: spots on the sides are larger than scales and not clearly aligned (vs. smaller than scales and rather well-aligned); stripe from the snout to the eye is interrupted (vs. continuous); quadrate bone with a spine (vs. none); maxilla reaching both a vertical and a horizontal line from orbit (vs. just to the ventral rim); cheek-scale rows modally 7 (vs. 6 or fewer); interradial scales on dorsal fin arranged in a row (vs. distally in two rows); dorsal and anal fins without filaments (vs. bearing filaments); anal and medial gut-loops not adjacent, well separated by the stomach and the liver (vs. always adjacent); rostral end of maxilla is notched or at least concave (vs. convex, notch absent); caudal ocellus blue in life (vs. white) (Ref. 74403).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02692 (0.01189 - 0.06092), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.4 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).
