A key to the genera of Tachinini from the Caribbean is presented. Two new generic synonyms are proposed: Hystriciella Townsend, 1915 and Parajwinia Townsend, 1928 both = JurineUa Brauer & Bergenstamm, 1889, resulting in JurineUa pilosa (Drury), new combination and JurineUa obesa (Townsend), new combination. Key Words: Diptera, Tachinidae, Tachinini, JurineUa, Caribbean, taxonomy JurineUa Brauer & Bergenstamm is a New World genus of Tachinini that ranges from southwestern United States to southern Brazil and northern Argen-tina. All of the described species are included in Guimaraes (1971) who listed 53 species in JurineUa, and one each in the genera HystricieUa Townsend and Parajwinia Townsend, which I consider to be congeneric. During collecting in the Dominican Republic I obtained speci-mens of a striking new species that is described herein (my material deposited at the Department of Entomology, Smithsonian Institution, Washington, DC, cited below as USNM). Additional specimens were made available from material collected during several expedi-tions by colleagues from the Carnegie Museum of Natural History, Pittsburgh, PA (cited below as CMNH). Paratypes are also deposited at the Canadian National Collection, Agriculture Ca-nada, Ottawa (cited below as CNC). Members of the tribe Tachinini are moderate to large tachinids that have the prosternum bare, the first postsutural supra-alar bristle at least as long and stout as the first postsutural dorsocentral bristle, and the hind margin of the hind coxa setose, usually over the entire hind margin (but if sparse, present at least on the posterolateral corner). Tachinines are a very diverse tribe in Central and South America, particularly at middle and high elevations, that includes several hundred species. However, the fauna of the Caribbean islands is surprisingly depau-perate, with fewer than a dozen recorded species. This undoubtedly reflects lack of collection to some extent, but in my experience in the Dominican Republic tachinines are truly scarce. Since there are a small number of Caribbean genera and most species in the region are poorly known, it seems worthwhile to present a generic key at this time to facilitate their identification.
