Short description Morphology | Morphometrics

Anal soft rays: 13 - 15; Vertebrae: 42 - 44. Distinguished from its congeners in having a dorsal caudal plate that supports eight principal rays; ventral caudal plate that articulates with six or seven rays; dorsal caudal-fin lobe with seven branched rays; dorsal caudal-fin lobe long, up to approximately 35% SL; ventral caudal-fin lobe with 15-19 rays; ventral caudal-fin lobe with six branched rays; forked caudal fin; and short maxillary barbels, 33.3-40.4% SL. Differs further from Nemuroglanis lanceolatus in having shorter anal-fin base, 12.4-18.1% SL; and longer caudal peduncle, 17.5-20.1% SL; and from N. pauciradiatus in having more vertebrae, 42-44 and more anal-fin rays, 13-15 (Ref. 55662).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00400 - 0.03785), b=2.99 (2.74 - 3.24), 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
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
