Abstract
An ongoing revision of the American dinematichthyine fishes (Ophidiiformes, Bythitidae) based on examination of about 2000 specimens will be published in two parts. This publication is Part I, which includes 209 specimens in the genera Dinematichthys (one W. Atlantic species), Gunterichthys (one W. Atlantic and two new E. Pacific species), Ogilbichthys (new genus with seven new W. Atlantic species), Pseudogilbia (new genus with one new W. Atlantic species) and Typhliasina (resurrected with one W. Atlantic cave species). The diagnostic characters are male pseudoclaspers, head pores, otoliths, gill rakers, morphometric proportions, fin ray and vertebral counts. Part II will comprise the revision of the speciose and abundant genus Ogilbia.
