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.
