Etymology: Leporinus: Latin, lepus, leporis = rabbit (Ref. 45335); parvulus: The name parvulus is from the Latin adjective which means thin or slender, in reference to its slender body.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 12; Anal soft rays: 10; Vertebrae: 35. This species can be diagnosed from other species of Leporinus (juveniles and adults), except L. moralesi and L. striatus, by the presence of dark midlateral stripe extending onto the middle caudal-fin rays. It differs from L. moralesi by having dark midlateral stripe extending from the snout to the caudal fin (vs. dark midlateral stripe extending from the vertical through the dorsal fin to the caudal fin), and five dark transverse bars between the head and the dorsal-fin origin in specimens of approximately 60 mm SL or more (vs. four). It can be distinguished from L. striatus by having a single dark longitudinal stripe on the body (vs. four), and dark transverse bars on the dorsal portion of the body (vs. absent) (Ref. 93868).

Found in rocky pools at rapid stretches. Occurs syntopically with Leporinus vanzoi (Ref. 93868).

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=0.01047 (0.00456 - 0.02402), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±0.1 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.).

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