In East Asia, the mayfly genusEphoron, a member of Polymitarcyidae, has been classified into three species:Ephoron eophilum,Ephoron limnobium, andEphoron shigae. Using the nuclear histone 3 and internal transcribed spacer 1 and mitochondrial 16S rRNA and cytochromecoxidase subunit I genes, we investigated the phylogenetic relationships of these mayflies.Ephoron limnobiumformed polyphyletic relationships within the clade of JapaneseE. shigaeand shared identical sequences withE. shigae, suggesting thatE. limnobiumis a synonym ofE. shigae. Monophyly was supported inE. eophilum, KoreanE. shigae, andE. limnobium+ JapaneseE. shigae.Ephoron eophilumthat co-occurs with the otherEphoronspecies has several peculiar traits in its adult swarming period and karyotype. This suggests that both pre- and post-zygotic isolation are likely to have promoted speciation of theseEphoronspecies. The divergence betweenE. eophilumandE. shigaewould have occurred from the late Late Miocene to Early Pliocene according to the Bayesian relaxed clock model calibrated using the mitochondrial substitution rate. The area currently inhabited byE. eophilumemerged above sea level some 0.1 Mya, suggesting thatE. eophilummoved into this area from other areas that it occupied prior to this time.Biological Journal of the Linnean Society, 2013,109, 181–202.
