| The American grapsid crab Sesarma rubripes, classified as Metasesarma rubripes by Rathbun (1918), was compared with M. rousseauxi, the type species of Metasesarma, and was found to be different in a number of characters. On the other hand, S. rubripes is very close to those species of American Sesarma that are considered to be members of the subgenus Chiromantes. The characters common to S. rubripes and the American Chiromantes can be interpreted as synapomorphies by means of an outgroup comparison. Aratus pisonii and the West African Sesarma elegans are further members of the group in question and both share special derived characters with S. rubripes. As a consequence, S. rubripes should be returned to the genus Sesarma. It is recommended, however, to... |

| Terrestrial arthropods are poorly known from the Cenozoic of Jamaica. A probably Late Pleistocene land crab, Sesarma primigenium sp. nov., is described from the Western Cement Company Cave, parish of St. Elizabeth, southwestern Jamaica. The same species is also tentatively recognised from the Late Pleistocene Red Hills Road Cave, parish of St. Andrew, eastern central Jamaica. The propodi of the new species are moderately globose, with an upper margin that is comparatively short and finely granulate ridged; the fingers are obscurely spooned and gaped; and the in-turned fixed finger is in line with, and a litt le shorter than, the basal margin. Of the nine extant endemic members of this subgenus in Jamaica, S. jarvisi Rathbun and S. verleyi Rathbun have... |
