Macrophthalmus setosus is a species of sentinel crab found on the east coast of Australia, from around Queensland to Sydney.[2] Macrophthalmus setosus is found low down on muddy river and creek banks and in exposed sea grass areas in tidal zones, at times near mangroves.[2] Males have a tooth on the upper claw (dactyl). The carapace is around 40 mm wide, and rectangular, greater than 1.7 times wide than long.[3] Eye stalks are long and thin.
