Tubuca flammula was formerly a member of the genus Uca, but in 2016 it was placed in the genus Tubuca, a former subgenus of Uca.[3][4][5]
Description
Like other fiddler crabs, Tubuca flammula males have one claw that is significantly larger than the other, while females have two equal-sized smaller claws. It has a black carapace with two white or pinkish parallel marks running fore and aft near the centre and a solid red band across the front of the carapace. The claws are bright red-orange and the eyes are close together.[6]
