Confirmation of occurrence of Ixodes (Pholeoixodes) rugicollis Schulze et Schlottke, 1929 (Acari: Ixodidae) in Poland, including the morphological description and diagnostic features of this species.

Research on feline and canine ticks was conducted in the years 2004-2005 in the vicinities of Przemyśl, in the village of Torki (Medyka region) and in Przemyśl. Ticks were collected by examining thoroughly the bodies of cats and dogs. Ticks were preserved in 70% ethyl alcohol and their taxonomic identity was determined. It was confirmed that dogs and cats in the study sites carried four species of ticks: Ixodes (Ph.) rugicollis, I. (Ph.) hexagonus, I. (Ph.) crenulatus and I. (I.) ricinus. Ixodes (Ph.) rugicollis was shown to be a common species among the ectoparasites on these hosts and therefore is considered now to be a regular component of the Polish fauna. Morphological characteristics of all the development stages of I. rugicollis are given in the paper.
