Two new species of Spatiodamaeus Bulanova-Zachvatkina, 1957, S. gladius sp. nov. and S. conjungenus sp. nov. are described from soil and leaf litter samples in Sichuan and Yunnan Provinces, Southwestern China. Adults of the new species S. gladius sp. nov. can be easily distinguished from other Spatiodamaeus species by the combination of the rather short, lanceolate and smooth interlamellar setae and the gladiate-shaped spinae adnatae. Adults of the other new species, S. conjungenus sp. nov., can be easily distinguished from other known species by the following characters: conjoint ridges connecting the insertions of all notogastral setae, c- and l-series are thick and slightly barbed, while h-series is smooth, attenuate, narrowly lanceolate, with a middle vein and radially directed and the additional pair of tubercles between Vp and Sp on the ventral plate.
