In the present paper the genera Uroactinia and Trichouropoda are reporte d for the first time in China, and two new species of above mentioned genera ar e described. All the type specimens are deposited in the National Base of Plague and Brucellosis Control, Baicheng City, Jilin Province. 1. Uroactinia fusina Ma, sp. nov. (Figs.1～7) ♀. Length and width of idiosoma, holotype 827×597 μm, paratype 908×632 μm. Marginal shield fused to dorsal shield anteriorly. Dorsal setae thin, but J 4 and J 5 long and stout. Coxae I close each other. Lacinia of tritosternum 3 fu rcate. Genital shield shuttle shaped, with two strip like structures. Leg groo ve distinct, with metapodal line. Stigma large, anterior curve of peritreme U s haped. Tectum large, with arc like anterior margin. Both digits of chela subequ al in length, fixed digit bearing umbrella like membraneous apical process, mar gin of umbrella with one row of denticles. The new species is similar to Uroactinia brasiloides Hirschmann, 1990, but i n the new species dorsal setae J 4 and J 5 long and stout, genital shield with two strip like structures, membraneous apical process of chela with one row of denticles; in the latter species all dorsal setae short, genital shield with ma ny minute spines, membraneous apical process of chela with one row of thin silks . Holotype ♀, paratype 1♀, from grassland soil, in Taipingchuan (44°24′N, 123 °11′E), Changling County, Jilin Province, Ⅷ 1962, collected b y Ma Liming. 2. Trichouropoda hejianguoi Ma, sp. nov. (Figs.8～10) ♀. Idiosoma 655 μm long and 529 μm wide. Marginal shield fused to dorsal shie ld anteriorly, dorsal setae thin. Genital shield broad, anterior margin round, p osterior margin slightly concave. Leg groove distinct, metapodal line lacking. B oth digits of chela subequal in length. The new species is similar to Trichouropoda patavina (G. Canestrini, 1885), but in the new species marginal shield without denticles, dorsal and ventral set ae simple; in the latter species marginal shield with denticles at posterior par t, dorsal setae brush shaped, ventral and perianal setae pilose. Holotype ♀, paratype 1♀, from grassland soil, in Taipingchuan, Changling Count y, Jilin Province, Ⅷ 1962, collected by Ma Liming. The new species is named in honour of Prof. He Jianguo, famous plague specialist of China.
