Abstract

Two species of Amblyomma Koch, 1844 occur in Chile: A. parvitarsum Neumann, 1901 and A. tigrinum Koch, 1844. Despite published reports of A. americanum (L., 1758), A. maculatum Koch, 1844 and A. varium var. albida Neumann, 1899 from Chile, these three taxa do not occur there. Amblyomma inflatum was described from Chile, but this species is a nomen dubium. There are Chilean records for the terrestrial tortoise tick A. argentinae Neumann, 1904, but this species is thought to be exotic because no natural populations of terrestrial tortoises exist in Chile. Herein we present new records of A. argentinae from the terrestrial tortoise Chelonoides chilensis (Gray, 1870), illegally introduced from Argentina, and of A. tigrinum Koch, 1844 from the fox Pseudalopex griseus (Gray, 1837) in Chile’s Region V.

Key words: Ixodidae, Amblyomma, Amblyomma argentinae, Amblyomma tigrinum, Chile
