Morphology | Morphometrics
soft rays: 8;
Vertebrae: 34 - 35. Presence of acuminate scales above and below lateral line on caudal peduncle. This characteristic is shared with N. spiniferus. Other diagnostic characters include: 8-12 very regular dark bars (vs. not very regularly shaped bars in N. spiniferus), 3-5 times wider than interspaces, the middle area of the bars being often lighter brown than the margin or as light as the background, the bar then being vertically split into two thin bars; dorsal length of head 18-22% SL (vs. 21-23%); process of acuminate scales shorter than (versus as long as) rest of scale, its base width about 1/4-1/3 of scale width (versus about 1/2).
Inhabits fast flowing forest streams with acidic water and sand-gravel substrate (Ref. 85309).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00327 - 0.01463), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
