The tick collection of the Museu de Historia Natural Capão da Imbuia was first sorted in the end of the 80's, and a list of specimens was published in 1992. During the last ten years, the collection has grown substantially and became the depository collection for type-specimens. The collection is the most regional representative depository of ticks from the State of Paraná, and it is one of the four largest Brazilian collections in number of specimens. All material was revised, and the data were computerized and catalogued in cards. To date, the collection includes 504 vials, with 2,073 specimens, belonging to 25 species and six genera of the families Argasidae and Ixodidae. The ticks were collected in regional and state parks and in green areas from 60 municipalities distributed within eight Brazilian states. This catalogue corrects some of the records published in 1992 for the state of Paraná and records new host species for Amblyomma aureolatum (Pallas, 1772), A. cajennense (Fabricius, 1787), A. longirostre (Koch, 1844), A. tigrinum Koch, 1844, Ixodes aragaoi Fonseca, 1935, I. auritulus Neumann, 1904, I. fuscipes Koch, 1844 and I. paranaensis Barros-Battesti, Arzua, Pichorim & Keirans, 2003. Amblyomma brasiliense Aragão, 1908, A. coelebs Neumann, 1899, A. nodosum Neumann, 1899 and I. fuscipes are recorded, for the first time, from the state of Paraná; A. longirostre from Rio Grande do Sul; I. fuscipes from Santa Catarina; I. schulzei Aragão & Fonseca, 1951 from Rondônia; and A. rotundatum Koch, 1844 from Bahia. In addition Haemaphysalis juxtakochi Cooley, 1946 and I. fuscipes are recorded for the first time, infesting birds.
