Eokrefftia ("dawn Krefftia") is an extinct genus of lanternfish that inhabited the seas around Europe and Australia throughout the Paleogene.^[1]^[2] Known only from its distinctive fossilized otoliths, it appears to be one of the earliest definitive fossil members of the lanternfish lineage. It may belong to the extinct subfamily Eomyctophinae.^[3]

The following species are known:^[4]

†E. paviai Schwarzhans & Carnevale, 2024 - late Oligocene of Italy (Antognola Formation)^[3]
†E. prediaphus Schwarzhans, 1985 (type species) - late Paleocene of South Australia (Dartmoor Formation)^[2]
†E. sulci (Nolf, 1988) - Early to Late Eocene (Ypresian to Priabonian) of Italy (Marne di Monte Piano Formation), Middle Eocene (Lutetian) of France (Aquitaine Basin)^[4]^[5] (=Diaphus sulci Nolf, 1988)

The otoliths of Eokrefftia can be easily confused with those of the extant lanternfish genus Diaphus, which are also present as fossils in the same deposits.^[4]
