Rayons mous dorsaux (Total) : 16 - 19; Rayons mous anaux: 20 - 23. Diagnosis: more elongate than Cithardium and Citharinus species; body depth 2.2-2.7x and head length 3-3.7x SL; caudal peduncle 0.7-1.1x long than deep; head 1.6-2.0x long than wide; short snout, 1.0-1.7x of eye diameter; pectoral fins almost half of head length; adipose fin 0.3-0.7x its distance to dorsal fin; caudal fin with symmetrical lobes (tips becoming round in adults); cycloid scales; scale formula 7.5-9.5/50-56/10.5-12.5; 7.5-9.5 scales between lateral line and dorsal fin origin; 16-19 dorsal fin branched rays; 20-23 anal fin branched rays (Ref. 2938, 81281).

Monospecific, distinguished from other genus of family by the body form which is more elongated than 2 other genus: Citharidium and Citharinus (Ref. 2938).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01585 (0.00617 - 0.04070), b=2.96 (2.74 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.0 ±0.1 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (61 of 100).
