Angustopila psammion is a species of land snail belonging to the subfamily Hypselostomatinae of the family Gastrocoptidae. It was described in 2022.[1]

This species was discovered by scientists scrutinising a small pothole-like cave located in northern Vietnam, according to the original description published in Contributions to Zoology.[2] According to National Geographic, this is the smallest species of land snail ever found. This species' shell measures 0.6 millimeters in diameter.[3][4] In comparison to other land snails in its family, the Angustopila psammion has a smaller parietal tooth and a shorter spire, however it has a much wider umbilicus.[5]

Etymology

"Psammion (ψαμμιών)" derives from the ancient Greek word for "grain of sand."[4]
