This paper also reports on a new species collected in Mt. Tinmu,ZhejiangProvince, which is named Sinocapritermes tinmuensis sp. nov.Comparison: The soldier of S. tinmuensis may be distinguished from S. vicinus by itsnarrowest width of postmentum 0. 20--0. 22 mm and its smaller dimensions.The soldier of S. tinmuensis may be separated from S. mushae by its largerdimensions and its narrowest width of postmentum 0.20--0. 22mm The imago of S.tinmuensis may be separated from S. vicinus and S. mushaeby its larger dimensions.Type locality: Mt. Tinmu (30. 4°N, 119.5°E), Zhejiang Province: soldiers(holotype, paratype). imago (holomorphotype, paramorphotype) and wor-kers,collected by Gao Daorong and Wu Yiduo.22 April, 1986, under a stone.Holotype deposited in Shanghai Institute of Entomology, Academia Sinica.Paratypes deposited separately in the Nanjing Institute of Termite Controland the Shanghai Institute of Entomology.
