Description of two new species of Dermacentor Koch, 1844 (Acari: Ixodidae) from Oriental Asia.

Dermacentor tamokensis n. sp. and Dermacentor pseudocompactus n. sp. (Acari: Ixodidae) are described based on adults ex wild boar and vegetation from China, India, Malaysia, and Vietnam and males ex wild boar from Nepal, respectively. Adults of D. tamokensis n. sp. are similar to those of D. taiwanensis Sugimoto, 1935 and D. atrosignatus Neumann, 1906 but can be distinguished by the colour pattern of the conscutum and scutum, the size and density of punctations on the pseudoscutum and scutum, the width of the cornua, and the shape of female genital structures. Males of D. pseudocompactus n. sp. are most similar to those of D. compactus Neumann, 1901 but can be distinguished by the colour pattern, sculpture and punctations of the conscutum, and the shape and length of the coxal spurs.
