땅딸이도마뱀붙이속

땅딸이도마뱀붙이속(Least gecko)은 아메리카 대륙에 서식하는 도마뱀붙이류의 일속이며 다른 도마뱀붙이류와는 아주 작은 크기, 찢어지지 않고 둥근 동공, 각각의 발가락에 단 한 개씩 난 둥근 빨판 혹은 비늘로 구별할 수 있다. 이 속의 학명은 발가락의 둥근 비늘에서 유래한 것이다.(Sphaero = 둥근, dactylus = 손가락) 이 속의 모든 종들은 상당히 작지만 자라구아땅딸이도마뱀붙이, 버진아일랜드땅딸이도마뱀붙이의 두 종은 정말로 작아서, 주둥이-항문 길이가 1.6cm에 불과하며 전 세계에서 제일 작은 파충류로 여겨진다. 학명의 일부를 그대로 따서 스페로(Sphaero)라고 불리기도 한다.
