Leptotyphlops is a genus of nonvenomous blind snakes, commonly known as slender blind snakes and threadsnakes,[2] in the family Leptotyphlopidae. The genus is endemic to and found throughout Africa. 11 species have been moved to the genus Trilepida, and other species have been moved to the genera Epacrophis, Epictia, Mitophis, Myriopholis, Namibiana, Rena, Siagonodon, Tetracheilostoma, and Tricheilostoma.


Most species of Leptotyphlops look much like shiny earthworms. They are pink or brown, and their scales give them a segmented appearance. Other species are black in color, but have the same general body structure. Their common name comes from the fact that their eyes are greatly reduced almost to the point of uselessness, and hidden behind a protective head scale. The species which are called thread snakes are so named because of their very narrow, long bodies.

All blind snakes including those of the genus Leptotyphlops are burrowing snakes, spending most of their time deep in loose soil, typically only emerging when it rains and they get flooded out.

The primary diet of Leptotyphlops is ant and termite larvae.
