Zoological Journal of the Linnean Society 204: 1-30, DOI: 10.1093/zoolinnean/zlaf048 ABSTRACT A new genus of heptapterid catfish, Magdalenichthys gen. nov., largely ignored for the past two decades is herein described. Comprehensive examination of specimens in Colombian ichthyological collections and additional samplings in the Magdalena basin were the base for an integral analysis using morphological characters, DNA barcode delimitation, and molecular phylogenetic analyses to assess monophyly and relationships of the new genus, and to delimit and diagnose four new species, Magdalenichthys lundbergi sp. nov., Magdalenichthys mompox sp. nov., Magdalenichthys poira sp. nov., and Magdalenichthys yariguies sp. nov., endemic to the Magdalena basin.
