определительные ключи | морфология | морфометрия
членистые (мягкие) лучи анального плавника: 8. Dionda nigrotaenita is similar to its congener D. serena but differs from it by having eye shorter than snout and 8 anal rays (Ref. 86798).
Inhabits rocky pools, sometimes runs, of headwaters, creeks, and small rivers. Usually occurs among filamentous algae (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
