Redescription and revision of Georges Demoulin’s Eocene Baltic amber Heptageniidae (Insecta: Ephemeroptera)
Abstract The vast majority of Cenozoic fossil records of mayflies (Ephemeroptera) are represented by adult specimens, and Eocene Baltic amber is no exception. Representatives of the family Heptageniidae Needham, 1901 were described from adult males and females during the mid-twentieth century by Georges Demoulin, whose work substantially advanced the knowledge of this rheophilous component of the fossil aquatic insect fauna.
Nebesna sotnia gen. & sp. nov. from Baltic amber supports a Pangean distribution of the amphinotic family Ameletopsidae (Ephemeroptera) - Scientific Reports
Abstract Extant representatives of the mayfly family Ameletopsidae Edmunds, 1957 as well as other three small families (Nesameletidae Riek, 1973, Oniscigastridae Lameere, 1917 and Rallidentidae Penniket, 1966) traditionally have been classified within the paraphyletic superfamily Siphlonuroidea. Except for Rallidentidae, which are endemic to New Zealand, they have an amphinotic distribution.
A new mayfly subfamily sheds light on the early evolution and Pangean origin of Baetiscidae (Insecta: Ephemeroptera) - Scientific Reports
Abstract The family Baetiscidae Edmunds & Traver, 1954 is recognisable among mayflies due to its bizarre larvae, equipped with a robust and spiked thoracic notal shield covering part of the abdomen up to sixth segment. Originally being described as extant species from the USA and Canada, Baetiscidae were later found in the fossil record as well, specifically in Cretaceous of Brazil and Eocene Baltic amber.

A new Gondwanan mayfly family from the Lower Cretaceous Crato Formation, Brazil (Ephemeroptera: Siphlonuroidea: Astraeopteridae fam. nov.) - Scientific Reports
Abstract The adult holotype of the fossil mayfly Astraeoptera cretacica Brandão et al. 2021 from the Cretaceous Crato Formation, Brazil, is reviewed and attributed to a new family Astraeopteridae fam. nov. Based on alate specimens, we also describe further new representatives of Astraeopteridae fam. nov., namely Astraeoptera vitrea sp. nov. and Astraeoptera oligovenata sp. nov., as well as the new genus and species Eosophobia acuta gen. et sp. nov.

Cenozoic origins of the genus Calliarcys (Insecta, Ephemeroptera) revealed by Micro-CT, with DNA barcode gap analysis of Leptophlebiinae and Habrophlebiinae | Scientific Reports
Abstract Mayflies (Ephemeroptera) are among the oldest pterygote insects, with the earliest fossils dating back to the Late Carboniferous. Within mayflies, Leptophlebiidae are a highly diverse and widespread group, with approximately 140 genera and 640 species. Whereas taxonomy, systematics, and phylogeny of extant Leptophlebiidae are in the focus of extensive studies, little is known about leptophlebiid fossil taxa.
