Eomyctophum ("dawn Myctophum ") is an extinct genus of lanternfish that inhabited the Peri-Tethys region and later the Paratethys Sea from the Eocene to the Oligocene. [1] It is the only member of the extinct subfamily Eomyctophinae, although Eokrefftia may also belong in it. [2] Its remains are known from throughout eastern Europe & western Asia in both the Caucasus and Carpathians, and comprise both articulated skeletons and otoliths, suggesting it was a particularly common fish. [3] [4] The earliest known member of the genus was identified from the Early Eocene of Italy in 2025, millions of years earlier and further west than the other species. [5]

The following species are known: [3]

The former species E. gracilis and E. limicolus are now placed in the blackchin Beckerophotus and the lanternfish Oligophus respectively. [3]
