Acknowledgments:

Our sincere thanks go to Dr. N.A.

We are also indebted to Dr. J. Keirans (former curator of the U.S. National Tick collection, Institute of Arthropodology and Parasitology, Georgia Southern University, Statesboro) and Prof. A.B.

Annotation:

Hyalomma (Euhyalomma) anatolicum Koch, 1844 and Hyalomma (Euhyalomma) excavatum Koch, 1844, previously considered subspecies of H. anatolicum, are reinstated as valid species after the examination of numerous specimens of all stages from localities throughout their distribution range. They are clearly distinguishable on existing as well as new diagnostic morphological characters of both their adult and immature stages. Geographic sympatry and peculiarities in their host-parasite relationships further confirm their specific status.
