Four new species of the tick genus Antricola Cooley and Kohls, 1942 (Acari: Argasidae, Antricolinae) are described from specimens collected on bat guano at hot caves in Cuba and Curacao. A. centralis n. sp. is a species closely related to A. occidentalis Cruz, but differs in the structure of the dorsomarginal tubercles and submarginal dorsal fold. A. hummelincki n. sp., previously reported as A. silvai Cerny from Curacao, is a very small species with minute spiracles and a partly developed postanal groove. A. armasi n. sp, is characterized by the presence of three strong tubercles behind the postanal groove. A. siboneyi n. sp. is a unique Antricola species in having the spiracle large in the female but very small in the male. Both sexes can be easily determined by the peculiar structure of the postanal groove.
