J. Bruce first described it in 1967 based on eight specimens ranging from 4 millimetres (0.16 in) to 7.6 millimetres (0.30 in).[3] Periclimenes Imperator is now considered a junior synonym of Zenopontonia Rex.[1]
Periclimenes imperator lives in water up to 45 metres (148 ft) in depth,[4] and can grow to a length of 1.9 centimetres (0.75 in).[5]
