Vial L., Camicas J.L.. 2009. In : by Friedhelm Krupp; Wilhelm Büttiker; Iyad Nader; Wolfgang Schneider (eds.). Fauna of Arabia. Mollusca, Amblypygi, Acari, Coleoptera, Hymenoptera, Diptera. vol. 24. Basel : Karger, p. 135-143.

The morphological description of a new soft tick species collected in Oman twenty years ago by W. Büttiker is given. The features of the nymphs and the larvae are characteristic of the genus Ornithodoros Koch, 1844 and of the subgenus Alveonasus Schulze, 1941. Examination of the larvae shows a specific combination of an O. (A.) foleyi-like body setal formula and setal location, and an O. (A.) canestrinii-like dorsal plate, as well as a unique hypostome longer than in all other Ornithodoros (Alveonasus) species and a unique palpal article III as long as articles II and IV, unlike all other Ornithodoros (Alveonasus) species. This new species is named O. (A.) buettikeri as a token of our esteem for its discoverer. Its relationships with the other Ornithodoros (Alveonasus) species are discussed.
