Three new species of the spider genus Liphistius (Araneae, Mesothelae, Liphistiidae) from Thailand

We diagnose and describe three new species of the primitively segmented spider genus Liphistius from Thailand, based on male palp and female genital morphology: L. hatyai Zhan & Xu, sp. nov. (ay), L. keeratikiati Zhan & Xu, sp. nov. (ay), and L. inthanon Zhan & Xu, sp. nov. (ay). The classification of the three new species of Liphistius is discussed: L. hatyai sp. nov. and L. keeratikiati sp. nov. are assigned to the trang-group, and L. inthanon sp. nov. is placed in the bristowei-group according to male palp and female genital morphology.
