The female of Ixodes stilesi Neumann, 1911 (Acari Ixodidae) is redescribed and the male and nymph are described from specimens collected from Pudu puda (Molina) (Artiodactyla: Cervidae) in Chile. Both sexes of I. stilesi have characteristics of the subgenera Ixodes Latreille, 1795 and Ixodiopsis Filippova, 1957. The females of I. stilesi are peculiar in having the combination of the sinuous scutum outline, rounded porose areas with distinct borders separated by the width of one area, slender and long palpi, and two subequal spurs on coxa I. The male is unique in having a combination of a posteriorly wrinkled marginal folder, a basis capituli longer than wide, a non-crenulate hypostome toothed portion, two spurs on coxa II to IV and the presence of a pseudoscutum. The nymph of I. stilesi has blunt anterior and posterior processes on palpal article I (characteristics of the subgenus Ixodiopsis and some Pholeoixodes Schulze, 1942) and a wing-shaped basis capituli with a prominent triangular cornua. Phylogenetic analyses based on 16S mitochondrial rDNA sequences of 12 Neotropical and two Australian Ixodes species, plus three argasids, were carried out to clarify the position of I. stilesi. The results of phylogenetic analyses and morphological characters indicate a close relationships between I. stilesi and two other Neotropical species of uncertain subgeneric status, I. neuquenensis Ringuelet, 1947 and I. sigelos Keirans, Clifford & Corwin, 1976.
