Mjukstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i analfenan: 13 - 15. Diagnosis: body depth 3.8-4.8x and head length 3.5-4.0x SL; eye diameter 2.8-3.8x head length; scale formula 7.5/39-43/4.5; 7.5 scales between lateral line and dorsal fin origin; 39-43 scales in longitudinal series; 14 scales around caudal peduncle; 8 dorsal-fin branched rays; 10-12 anal-fin branched rays (Ref. 2940, 81282).

Affinities: meristic characters close to R. nigeriensis (with more number of branched rays; shorter head length and mouth). Maximum TL was recorded at 15.5 cm (Ref. 2801).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00282 - 0.01229), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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