Uropeltoidea

The Uropeltoidea, also known as uropeltoid snakes, are a superfamily of snakes that contains uropeltids and Asian pipesnakes.
As of 2018, Uropeltoidea contains 97 species, including the eponymous shield-tail snakes and their relatives, 14 species of Asian pipesnakes, and three species of dwarf pipesnakes.
The taxonomy of boas, pythons, and other henophidian snakes has long been debated, and ultimately the decision whether to assign a particular clade to a particular Linnaean rank is arbitrary. The clade name Uropeltoidea emphasizes the relatively close evolutionary relationship among these 71 species, which last shared a common ancestor about 48 million years ago, in contrast to the more distant relationship between uropeltoids and their next closest relatives, pythonoids.
