Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7 - 8; Anal soft rays: 10 - 11; Vertebrae: 35. Can be differentiated from all other members of the Pseudecheneis by the absence of yellow spots or patches on the body (vs. presence). Differs from all congeners except Pseudecheneis longipectoralis in having longer pectoral fin, reaching to pelvic fin base (vs. not reaching); and distinguished from Pseudecheneis longipectoralis in having a longer caudal peduncle (28.2-32.9% SL vs. 24.9-28.2). Premaxillary tooth band semicircular with 2 or 4 teeth along outer edge; body covered with dense, tubercles distributed uniformly, some longitudinal tubercles among rounded tubercles; vertebrae 35 (Ref. 74729).

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 (0.00260 - 0.01333), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

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