The insular mole (Mogera insularis ) is a species of mammal in the family Talpidae. It is restricted to Hainan Island and Taiwan, where it is also known as the Formosan blind mole. The species was first described by Robert Swinhoe in 1863.
Mogera insularis is unique from other moles in the Talpinae family in that it has 32 chromosomes instead of 34 to 38 chromosomes. Additionally, Mogera insularis members also have a metacentric chromosome pair that is much larger than its other chromosome markers.
