Magdalenichthys lundbergi is a newly described genus of heptapterid catfishes endemic to Colombia’s Magdalena River basin. It was formally described on 8 July 2025 in the Zoological Journal of the Linnean Society, alongside three congeneric species (M. mompox, M. poira, and M. yariguies) based on specimens long overlooked in ichthyological collections. Habitat: Magdalenichthys lundbergi is found in the main tributaries of the upper basin of the Cauca River (Quinamayó, Mediacanoa, La Vieja, and Risaralda rivers). Etymology: The genus name Magdalenichthys: In allusion to the Magdalena River basin, remarking on the restricted geographic distribution of this heptapterid genus to the Cauca and Magdalena rivers, which together form the main hydrographic basin of the trans-Andean region of Colombia, framed by the Western, Central, and Eastern cordilleras, the most salient feature of the Colombian geomorphology. Gender masculine. The species name lundbergi: The species name is dedicated to John G. Lundberg, in recognition of its seminal contributions to the systematics of pimelodoid and heptapterid catfishes, and for being an inspiring milestone in the first author’s career (DoNascimiento et al. 2025). |
