Four new species are described: <em>M. borincana, coralia, millsi,</em> and <em>wrayi</em>. <em>Sulcuncus</em> Mills 1938 is treated as a subgenus of <em>Metasinella</em> and all the species except <em>M. acrobates</em> are moved to this subgenus. The femoral organ, a new area found on the metathoracic trochanters, is the eighth feature used to distinguish <em>Metasinella</em> s. str. and <em>Sulcuncus</em>. 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. ER -
