REMARKS

Latreille (1803: 67, 68, and footnote) stated the material was given to him by a young naturalist, Marcel Serres, who had collected it near Montpellier, on the coast of the Mediterranean Sea; and the species closely resembled Cancer marmoratus ( Fabricius, 1787) . Henri Milne Edwards (1837: 88) examined the material deposited in the MNHN collection, noting this species was very common along the rocky areas of Bretagne (Brittany), France, Italy, etc. Alphonse Milne-Edwards & Bouvier (1900: 109) synonymised Grapsus varius with Pachygrapsus marmoratus Fabricius, 1787 , the type locality of which is unknown ( Fabricius 1787: 319). From the original sample MNHN-B3526, with one male and one female, from the Mediterranean Sea, the male is hereby selected as the neotype of Grapsus varius Latreille, 1803 , MNHN-IU-2000-3526 (= MNHN-B3526). The female is registered as MNHN-IU-2000-1108 (= MNHN-B3526).
