Material examined. None.

Previous records from Panama. Gore & Abele (1976).

Distribution. East Pacific: Mexico and Panama (Las Perlas Is.) ( Gore & Abele 1976).

Ecology. Mainly intertidal; usually on sandy bottom under rocks or within corals ( Haig 1960; Gore & Abele 1976).

Remarks. According to Glassell (1936), M. smithi is remarkably similar to the eastern Pacific M. sinuimanus , for instance, in the ornamentation of the carapace, the general format of P1 and configuration of the carinae on the palm, as well as the telson composed of seven plates. However, in M. smithi , the carapace is flattened (not swollen as in M. sinuimanus ; the eyes are largely visible dorsally (vs. partly concealed in M. sinuimanus ); the mesial margin of the P1 carpus is more developed; and the P2–P4 are more elongate than in M. sinuimanus . Interestingly, based on molecular data, the two species do not seem to be closely related (Hiller & Lessios 2019).
