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]
