Tiomanium indicum

Tiomanium indicum, commonly known as the Tioman crab or the white clawed mangrove crab, is a crab in the family Sesarmidae. It inhabits the Western and central Indo-Pacific ocean, including Singapore, Malaysia, Australia (Queensland), the Philippines and New Guinea. Tioman crabs are supralittoral (live above the high tide line).[1] In Cairns, Australia they are known for moving in numbers in some seasons entering backyards and homes.[2] This species was originally described by H. Milne Edwards in 1837 as Sesarma indicum. It was placed in a new genus Tiomanium (originally Tiomanum) by Serene and Soh[3] The carapace is convex and 34 mm length. Key features that differentiate Tiomanium from Neosarmatium include a spine at the end of the upper inner margin of the cheliped palm and a spine on the upper inner angle of the carpus.[3]
