There are three types:

  • Three chipmunks, Lariscus insignis (F. Cuvier, 1821), Malay Peninsula, Sumatra, Java, Borneo
  • Mentawai three chipmunks, Lariscus obscurus ( Miller 1903), Mentawai Islands
  • Four chipmunks, Lariscus hosei ( Thomas 1892), northern Borneo

Some authors mention a fourth type, the Niobe Black chipmunk ( Lariscus niobe ) in Java and Sumatra. The four chipmunks is also sometimes placed in a separate genus Paralariscus.
