Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 8-9; Rayons mous anaux: 6; Vertèbres: 31. Distinguished from its congeners by the following characters: presence of transverse dark bands on pectoral-,pelvic- and anal-fin rays (vs. absence); 31 vertebrae (vs. 32), and by anterior portion of the compound supraneural-first dorsal-fin proximal radial contacting the neural spine of the 9th vertebra (vs. 10th). Differs from Rhinolekos garavelloi by the larger post-anal length (34.7-37.7% in SL vs. 29.0-34.6%); smaller thoracic length (14.7-18.0% in SL vs. 18.1-20.8%); and fewer plates in the dorsal series (24-28 vs. 30-35). Can be diagnosed from Rhinoleko schaeferi by the absence of premaxillary and dentary accessory teeth (vs. presence); and 21-24 mid-dorsal plates (vs. 18-20) (Ref. 86681).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00323 - 0.01701), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).

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