Short description Identification keys | Morphology | Morphometrics

Lebiasina ardilai is distinguished from all lebiasinins by its color pattern consisting of a narrow, nearly straight primary stripe, extending from posterior to humeral blotch to near the vertical through anal-fin origin, being nearly absent in females and conspicuously marked in males; the presence of four series of dark markings at the base of the scales of longitudinal series 2–5; the faint secondary stripe running onto scales of second and third longitudinal row of scales; and the posteriorly displaced caudal blotch, not reaching the posterior tip of caudal peduncle. The new species also differs from its Guyana Shield relatives L. taphorni Ardila-Rodríguez, L. unitaeniata (Günther), L. uruyensis Fernandez-Yépez, Lebiasina yepezi Netto-Ferreira et al. and L. yuruaniensis Ardila-Rodríguez by the lack of the intermediate stripe (Ref. 93551).

Facultative air-breathing in the genus (Ref. 126274)

Bayesian length-weight: a=0.00692 (0.00273 - 0.01753), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.4 se; based on size and trophs of closest relatives

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