REMARKS

The original samples MNHN-B4023 and MNHN-B3519 have an additional label by D. Guinot in 1972 with the indication “presumed syntypes ”. This was cited by Griffin (1973: 418), who mentioned “three syntypes ” in the MNHN when he recognised the species as a junior synonym of Leptograpsus variegatus . The specific name ansoni refers to the Commodore George Anson, famous for his Voyage around the world to disrupt or capture Spain’s Pacific possessions, reaching the Juan Fernández Archipelago in 1741.
