Taxonomic Etymology:
A skink with a vivid blue tail.
Emoia — Named by Gray in 1845; the etymology is unclear but may derive from a personal or locality name, possibly linked to Pacific island groups. It may be an arbitrary combination coined by the author.
cyanura — From Greek kyanos (κυανός), “blue,” and oura (οὐρά), “tail.” Refers to the bright blue coloration of the tail, especially in juveniles and younger adults.
