Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 4 - 7; Dorsal soft rays (total): 8 - 12; Anal spines: 1; Anal soft rays: 18 - 26. This species is distinguished and differs from L. sicculus by the following characters: Labidesthes vanhyningi have the anterolateral processes of the posttemporals
shorter than width of the base (vs. L. sicculus having the processes longer than width of base); with a midlateral stripe that does not taper, usually expanding, to insertion of pectoral fin in advance of the first dorsal-fin (vs. tapering to insertion of pectoral fin in advance of first dorsal fin); a ratio of thoracic length to abdominal length less than 2 (vs. greater than 2) (Ref. 104856).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00229 - 0.01150), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.1 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
