Grapsidae
The Grapsidae are a family of crabs known variously as marsh crabs, shore crabs, or talon crabs. The family has not been confirmed to form a monophyletic group and some taxa may belong in other families. They are found along the shore among rocks, in estuaries, marshes, and in some cases pelagic among drifting seaweeds and flotsam. Genera A number of taxa, formerly treated as subfamilies of the family Grapsidae are now considered families in their own right, including the Varunidae and Plagusiidae. Ten genera remain in the family, two of them known only from fossils: *''Geograpsus'' Stimpson, 1858 *'' Goniopsis'' De Haan, 1833 *''Grapsus'' Lamarck, 1801 *'' Leptograpsodes'' Montgomery, 1931 *''Leptograpsus'' H.

Leptograpsus
''Leptograpsus variegatus'', known as the purple rock crab, is a marine large-eyed crab of the family Grapsidae, found in southern subtropical Indo-Pacific Oceans. It grows to around shell width. It is the only species in the genus ''Leptograpsus''. __TOC__ Taxonomy ''Leptograpsus variegatus'' was first described in 1793 as ''Cancer. variegatus''. In 1803, ''C. variegatus'' was moved to the ''Grapsus'' genus and became ''Grapsus variegatus''. In 1818, 1842 and 1852, ''L. variegatus'' was described again as ''Grapsus personatus'', ''Grapsus strigilatus'' and ''Grapsus planifrons''. In 1853, Henri Milne-Edwards erected the ''Leptograpsus'' genus and used ''G. variegatus'' as the type taxon.MILNE EDWARDS, H. 1853. Memoire sur Ia famille des ocypodiens. Annales des Sciences Naturelles, Zoologie (3), 20: 165–228, pis 6–11. In his publication, Milne-Edwards recognized ''G. personatus'', ''G. strigilatus and G. planifrons'' to be synonyms of ''L. variegatus''. Milne-Edwards a ...
