There are some 87 species in this genus. They are noticed due to their large size and bright colour. They can be seen crawling along the ground, but are mostly seen along tree trunks, in forests throughout tropical Asia, from India to northern Australia.
They are unusual because of the direction of their coiling; most species of mollusc shells grow in one direction, but these will often be dimorphic (either direction) in the same populations. This is useful for studying asymmetry in animals.
Harvestmen are delicate looking arachnids with very long thin legs.
Many of the insects in the region, such as butterflies, are not endemic to Wallacea because of their ability to disperse through flight. They are usually shared species between Asia to the west or Australasia to the east, or sometimes even to both regions.
