A new species of terrestrial Isopoda, Ligidium acutangulum sp. nov., is described and illustrated based on material from China. The new species can be diagnosed by the apical part of the pleopod 2 endopod being acutely triangular, the inner margin straight, and the outer margin concave near a well-developed process. Type specimens are deposited in the Insect Museum, Jiangxi Agricultural University, Nanchang, P. R. China.
