Reef lobsters are distinguished from clawed lobsters (family Nephropidae) by having full claw
Claw

A claw is a curved, pointed appendage, found at the end of a toe or finger in most mammals, birds, and some reptiles. Somewhat similar fine hooked structures are found in arthropods such as beetles and spiders, at the end of the leg or Arthropod leg for gripping a surface as the creature walks....

An appendage in the broadest sense is an additional or subsidiary part existing on, or added to, something which can generally still function if the appendage has never existed or is later provided or grown, or will still perform a primary function if the appendage is removed....
 can press against a short projection from the penultimate one). Clawed lobsters have full claws on the first three pereiopods. Males, unlike those of nephropoid lobsters, have an extra lobe on the second pleopod, which is assumed to have some function in reproduction. Reef lobsters have a shallow cervical groove while clawed lobsters have a deep cervical groove .

Although there is no fossil record of reef lobsters, there is some evidence that they may be related to the extinct genus Eryma which lived from the Permo-Triassic
