1. The elapids in the past were considered to have two subfamilies–the Elapinae made of terrestrial species and Hydrophiinae made of the marine species.^[3] In 1997, Slowinski, Knight and Rooney found in their phylogenetic analysis using amino acid sequences from venom proteins, that the Australasian terrestrial species nested within the Hydrophiinae. This led to removing the Australasian terrestrial species and placing them in Hydrophiinae.^[4][3] This has been supported in subsequent recent genomic analyses, though these same studies also found the subfamily Elapinae to be paraphyletic in respect to the Hydrophiinae.^[5][6][7] These studies have found coral snakes, cobras and mambas, kraits, and African gartersnakes forming successive outgroups to Hydrophiinae.^[6][7] Since clade names are available for these groups with the exception of the Elapsoidea, bringing back the subfamilies Calliophiinae, Micrurinae, Najinae, and Bungarinae is ideal.
