The Antillean genus Metasinella is revised using specimens collected recently in Cuba and Puerto Rico. Four new species are described: M. borincana, coralia, millsi, and wrayi. Sulcuncus Mills 1938 is treated as a subgenus of Metasinella and all the species except M. acrobates are moved to this subgenus. The femoral organ, a new area found on the metathoracic trochanters, is the eighth feature used to distinguish Metasinella s. str. and Sulcuncus. A key to the subgenera and a key to all the species are included; a map details the geographic distribution of the species. Eighty figures supplement the descriptions.
