soft rays: 9. Differs from other species of Pseudecheneis by the combination of following characters: 9-14 transverse ridges on the thoracic adhesive apparatus; wide and flat snout, with ratio of snout width at mouth corner to distance between pectoral fin base larger than 0.75; caudal peduncle depth 6.1-9.3% SL and 29.4-46.7% in length of caudal peduncle; four yellow spots on caudal fin which are isolated and not connected with each other; premaxillary tooth band semicircular with six or eight teeth along its outer edge; body covered with dense, rounded tubercles distributed irregularly; tubercles increasing in density gradually from occipital to caudal peduncle; and 33 (17+16), 34 (17+17) vertebrae (Ref. 74729).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00347 - 0.01656), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this Subfamily-BS (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).
