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]
- †E. cozlae Ciobanu, 1977 - Early Oligocene of Romania
- †E. koraensis Daniltshenko, 1947 (type species) - Early Oligocene of the North Caucasus, Russia (including Pshekha Formation), Abkhazia, Azerbaijan, and Ukraine (Menilitic Formation) (=E. menneri Daniltshenko, 1967)[4]
- †E. mainardii Calzoni, Giusberti & Carnevale, 2025 - Early Eocene of Italy (Chiusole Formation)[5]
- †E. polysarcum (Gorjanovic-Kramberger, 1880) - Early Oligocene of the Czech Republic
The former species E. gracilis and E. limicolus are now placed in the blackchin Beckerophotus and the lanternfish Oligophus respectively.[3]
