Coleusia is a genus of Indo-Pacific pebble crabs of the family Leucosiidae. The six species currently recognised were formerly classed as members of the genus Leucosia; they were separated into Coleusia in 2006 based on the fusing of segments 3-5 on the abdomens of the males and the three times axial coiling of the shaft of the first pleopod, which bears a tufted lobe on its distal portion and has an elongated apical process.
