Aegista diversifamilia is a species of air-breathing land snails, a terrestrial pulmonate gastropod mollusk from Taiwan.

In 2003, a paper was published remarking on the morphological and genetic difference between the eastern and western populations of the species.

Eventually it was established that the eastern population was a separate species, divided from A. subchinensis by the Lanyang River.

It reminded us that Pulmonata land snails are hermaphrodite animals, which means they have both male and female reproductive organs in single individual.
