Dorsal spines (total): 0; Dorsal soft rays (total): 22-26; Anal spines: 0; Anal soft rays: 30 - 35. Diagnosis: Number of anal fin rays between 30 and 35; anal fin length 24.4-27.8% of standard length; preanal length 54.3-59.0% of standard length (Ref. 91771).

Biology     Glossary (e.g. epibenthic)

Type locality (Lufubu River) is a braided rocky channel with dense riparian forest; water flow rapid, but also deep pools providing slacker flow areas; substrate is rocky but with considerable amounts of leaf litter; some sections with mats of aquatic water ferns and mosses and filamentous algae (Ref. 91771).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00707 - 0.03721), b=2.83 (2.65 - 3.01), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
