This paper presents results of an investigation and listing of tick species found in China during a survey in all 28 provinces. This will be a step towards a definitive list of tick species and their distribution. To date, the tick fauna of this area consists of 117 species in the following families: Argasidae-Argas (7 species), Carios (4 species) and Ornithodoros (2 species); Ixodidae-Amblyomma (8 species), Anomalohimalaya (2 species), Dermacentor (12 species), Haemaphysalis (44 species), Hyalomma (6 species), Ixodes (24 species) and Rhipicephalus (8 species). Some well known ticks carrying and transmitting many infectious agents to man and domestic animals are also found in China. These include Ixodes persulcatus, Haemaphysalis longicornis, Rhipicephalus sanguineus, R. (Boophilus) microplus and Hyalomma asiaticum. It is worth mentioning that Ixodes rangtangensis Teng and Haemaphysalis xinjiangensis Teng should be relegated to a synonym of I. moschiferi and Hae. danieli, respectively. The distribution of ticks over the provinces of China is also discussed. The information on ticks in some areas such as Henan is not exhaustive.
