Abstract

Two new species of the family Pauropodidae: Dasongius liupanensis sp. n. and D. spatulatus sp. n. are described from China. Both of them have non-furcate setae on the collum segment, long setae p and q on the antennae, 6+6 setae on tergite II, furcate setae on the coxa, cylindrical setae on the trochanter of leg 9, and two appendages on the anal plate; these features are distinct from other congeners. The new species can be distinguished by the shape of the tergum of the pygidium, shape of the anal plate, as well as the shape of setae a1, a2, st and b1 on the pygidium. In addition, all species of the genus Dasongius are compared in detail.
