Parasesarma messa, commonly known as the maroon mangrove crab, is a species of burrowing crab found in Queensland, Australia.[2] It lives in mangroves in estuaries and sheltered bays.[2][3] It was originally described as Sesarma messa,[3] but was placed in the genus Parasesarma in 2017.[4] Perisesarma messa is also a synonym.[5]

The species name ‘messa’ comes from the initial letters of "Medially Expanded Second Segment of Abdomen".[3] The carapace is up to 25 mm (0.98 in) wide, with one tooth (notch) on the edge.[2] The claws are a dark maroon color to nearly black.[2] Claws in females are smaller than in males.[3]
