Etymology: Glyptothorax: Greek, glyptes = carver + Greek, thorax = breast (Ref. 45335); rhadinus: Name 'rhadinus' from the Latinized form of the Greek meaning 'slender', in reference to the very slender TAA of this new species.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 5 - 6; Anal soft rays: 8 - 9. This species is distinguished from its congeners by the following set of characters: thoracic adhesive apparatus width 1.9-2.2 times in its length, three dark bands on body that are sometimes connected by a dark midlateral stripe to form an elongate pale ovoid patch on the dorsolateral surface of the body; lack of a distinctly pale nuchal shield; thoracic adhesive apparatus without anteromedial striae; medial pit; striae in medial third of TAA slightly divergent from longitudinal axis and anastomosing; caudal peduncle depth 2.5-2.7 times in body depth at dorsal-fin origin; dorsal to adipose distance 15.5-20.0% SL; tip of adpressed pelvic fin just reaching anal-fin origin; and the lack of enlarged, prominent tubercles on the flanks, particularly below the lateral line (Ref. 1382277).
Body shape (shape guide): elongated; Cross section: oval.

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=0.00794 (0.00365 - 0.01726), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 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. 59153):  Low vulnerability (10 of 100). 🛈
