Rayons mous dorsaux (Total) : 10; Vertèbres: 39 - 41. Diagnosed from all other species of the genus in having an elongate projection on fourth ventral neural arc near the first neural postzygoapophysis and a very reduced hooks on all fins and the posterior end of dorsal lobe of the caudal fin (Ref. 83513).

Found in a creek characterized by an average dissolved oxygen of 5-8 mg/l and a relative humidity of 71-100%, conductivity of 301-367 us/cm, surface temperature of 18.5-24.5°C, and pH 5.8-8.0 (Ref. 83513).

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=0.00955 (0.00443 - 0.02057), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

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