MALDONADO-OCAMPO, Javier A.; SANTANA, Carlos David de  e  CRAMPTON, William G. R.. On Apteronotus magdalenensis (Miles, 1945) (Gymnotiformes: Apteronotidae): a poorly known species endemic to the río Magdalena basin, Colombia. Neotrop. ichthyol. [online]. 2011, vol.9, n.3, pp.505-514. ISSN 1679-6225.  https://doi.org/10.1590/S1679-62252011000300005.

Based on the examination of the two available paratypes and recently collected material, we present new data and information on the electric knifefish Apteronotus magdalenensis, a species endemic to the río Magdalena-Cauca basin in Colombia. Since Miles' description in 1945, this species was not collected until recent field work at the Torrents of Honda and additional localities. We present data on the external morphology, morphometrics, pigmentation and electric organ discharges (EODs), of A. magdalenensis. We also review its distribution, ecology and conservation status.
