[The World List of Ticks. 1. Argasidae and Nuttallielidae（Acari ∶ Ixodida)]

In ixodology, the world records of the nominated species of the ticks reached close to thousand. Towards the end of 2015, altogether 200 valid species names of Argasidae accommodated in 5 genera have been consensed by most of the world ixodologists, namely Argas 61 species, Ornithodoros 118 species, Antricola 17 species, Nothoaspida 2 species, and Otobius 2 species. The monotypic status of the genus Nuttalliella of Nuttalliellidae remained unchange. China is a country of poor in soft tick fauna, only 14 species were recorded so far. In order to facilitate the exchange of the scientific view-point among the colleagues about both ticks and tick-borne diseases in this country, a latest list of world argasid and nuttalliellid valid names was introduced. Meanwhile a Chinese scientific term for each valid species and named genus in conformity with the principle of simplicity and pithy, as well as systematization was proposed. A series of abbreviations for the nominated genera and subgenera of Argasidae was also suggested.
