4 NEW SPECIES OF ANTRICOLA TICKS (ARGASIDAE, ANTRICOLINAE) FROM BAT GUANO IN CUBA AND CURACAO

Four new species of the tick genus Antricola Cooley & Kohls, 1942 (Aca ri : Argasidae, Antricolinae) are described from specimens collected o n 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 t he structure of the dorsomarginal tubercles and submarginal dorsal fol d. A. hummelincki n. sp., previously reported as A. silvai Cerny from Curacao, is a very small species with minute spiracles and a partly de veloped postanal groove. A. armasi n. sp, is characterized by the pres ence 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 determ ined by the peculiar structure of the postanal groove.
