uroplatus phantasticus, the satanic leaf-tailed gecko, is a species of gecko indigenous to the island of madagascar. first described in 1888 by george albert boulenger, "u. phantasticus" is the smallest in body of the "uroplatus" geckos, though there is an ongoing debate as to whether one of its cousins, "u. ebenaui", is smaller because of its shorter tail. it may also be known as the eyelash leaf-tailed gecko or the phantastic leaf-tailed gecko.
