Geograpsus severnsi Paulay & Starmer, 2011

Severns' terrestrial crab



Taxonomy & Nomenclature

Allied to Geograpsus grayi (Paulay & Starmer 2011).


Conservation Status


Last record: 300 AD or later


The finding of sub-fossil remains of a terrestrial species of crab was a major find. Previously it was believed that no fully terrestrial decapod had colonized the islands. However, the species did not just colonize the islands, but at least several of them as sub-fossil remains have been found on Maui, Kauai, Molokai, Oahu, and Hawaii itself (Paulay & Starmer 2011, see Table 2).
