The phytogeographical distributions of Haemaphysalis juxtakochi, Ixodes pararicinus and Otobius megnini in Argentina are described from material collected mainly from 1978 to the present. H. juxtakochi was found in the northwestern area of the Amazonian domain and in the Chaco, Espinal and Pampean provinces of the Chaco domain. It was detected on Mazama spp., Tapirus terrestris, dog, cattle and on the vegetation. Most findings of I. pararicinus were from mountain rangeland, where it was found on cattle and in a lesser extent on horses. Ticks from Argentina classified as Ixodes ricinus were probably I. pararicinus. O. megnini was detected on cattle an sheep in the Andean Patagonian domain and in the Monte, Chaco and Espinal provinces of the Chaco domain. This thick is considered typical of arid and semiarid conditions, however the findings from the Espinal province where from areas with an annual rainfall over 900 mm.
Résumé
La distribution de Haemaphysalis juxtakochi, Ixodes pararicinus et Otobius megnini en Argentine a pu être établie grâce au matériel collecté de 1978 jusqu’à ce jour. H. juxtakochi a été trouvée dans les domaines Amazonien (région nord-ouest) et du Chaco (provinces de l’Espinal, Chaco et du Pampean) sur le chien, le bovin, Mazama spp. Tapirus terrestris et sur le couvert végétal. Par contre, I. pararicinus a été le plus souvent trouvé dans la prairie de montagne, sur les bovins et parfois sur le cheval. Il est possible que les tiques de l’Argentine classées comme Ixodes ricinus soient I. pararicinus. O. megnini a été trouvée sur les bovins et les ovins dans les domaines Andin-Patagonien et du Chaco (provinces du Monte, du Chaco et de l’Espinal). On a toujours considéré que cette tique se développait dans les régions arides et semi- arides, cependant les précipitations annuelles de la province de l’Espinal dépassent les 900 mm.
