Etymology: Pterobrycon: Greek, pteryx = fin + Greek, bryko = to bite (Ref. 45335).
Eponymy: Hugh McKennan Landon (1867–1947) was an Indianapolis businessman and philanthropist who helped finance the Chocó, Colombia, expedition that collected the holotypes of both Hemiancistrus landoni and Pterobrycon landoni. (Ref. 128868), visit book page.
More on author: Eigenmann.

Issue
No recent systematic descriptions, but its presence in río Atrato confirmed recently by Bork (2000a), imported alive into Germany as bycatch with Nematobrycon palmeri. See Bork (2000b) for a brief account of breeding this fish. See Weitzman & Menezes (1998) for relationships.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [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).

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

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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