Cardisoma longipes A. Milne-Edwards, 1867 Discoplax longipes is a species of terrestrial crab.

It is found in karstic caves on Pacific islands[2] and ranges from the Loyalty Islands to French Polynesia (the Guam population was recognized as a separate species, D. michalis, in 2015).

[3] Mating occurs in the caves, after which the females migrate to the sea to release their fertilised eggs.

[4] The genus Discoplax was for a long time synonymised with Cardisoma, but was resurrected in the late 20th century.
