Several larval, nymphal and female ticks belonging to the Ixodes auritulus species group were collected from Thraupis bonariensis (Gmelin, 1879) (Passeriformes: Thraupidae), Phrygilus fruticeti (Kittlitz, 1833), Sicalis olivascens (d´Orbigny & Lafresnaye, 1837) and Xenospingus concolor (d´Orbigny & Lafresnaye, 1837) (Passeriformes: Emberizidae) in Chusmisa (19° 40´S, 69° 10´W), Región de Taracapá, Region I, northern Chile. All these hosts and the collection locality are new for this species group. The gene sequence divergence between the I. auritulus group from Chusmisa and those from southern Argentina was 3.3%, but it remains unclear whether these populations represent different species.
