Tubuca dussumieri is a species of fiddler crab that is found in the western and south Pacific including New Caledonia, Indonesia, Malaysia, Taiwan, Japan, and northeastern Australia.

[1][2] Tubuca dussumieri males have one claw that is significantly larger than the other, while females have two equal-sized smaller claws.

[3] The male claw is red or orange on the lower half and white to yellow on the upper half, with granules on the wrist and a gutter along the lower claw.

[1] In Australia, it can be distinguished from Tubuca coarctata as the upper upper movable finger of the claw of Tubuca dussumieri is white or yellow white[1] with the lower finger mostly orange and the wrist (manus) blue-grey,[4] and that there is two rather than one grooves in the upper claw.

[3] Tubuca dussumieri was formerly a member of the genus Uca, but in 2016 it was placed in the genus Tubuca, a former subgenus of Uca.
