A new species of Cyrtopholis Simon, 1892 from Montserrat, with notes on some other Caribbean theraphosines (Araneae: Theraphosidae).

A new species of the Caribbean genus CyrtopholisSimon, 1892, Cyrtopholis montserratsp. nov. is described from the United Kingdom Overseas Territory (UKOT) of Montserrat, based on both sexes. Cyrtopholis femoralisPocock, 1903 is redescribed from the holotype male with the first figures of the genitalia of this Montserrat endemic spider presented. The endemic Saint Barthélemy species Cyrtopholis antillanaThorell, 1894stat. rev. is revalidated from synonymy with Cyrtopholis bartholomaei (Latreille, 1832) and non-type specimens of both sexes are described and diagnosed. Cyrtopholis innocua (Ausserer, 1871), C. intermedia (Ausserer, 1875), C. ischnoculiformis (Franganillo, 1926), and C. obsoleta (Franganillo, 1935) are proposed as nomina dubia, and Cyrtopholis respinusFranganillo, 1935 is confirmed as a nomen nudum.
