The Hispaniolan masked curly-tailed lizard (Leiocephalus personatus) is a lizard species from the family of curly-tailed lizards (Leiocephalidae). It is also known as the green-legged curly-tail and the jewelled curly-tail, due mainly to the bright metallic colouration of mature males. The species is sexually dimorphic with the males being considerably larger with impressive red markings on the head around the lower jaw. Females are much smaller and are brown in colour with ligher stripes running down the flanks.
