Distribution China (Wuyishan). Habitat Streamlet. Remarks This new species is similar to Torrenticola ussuriensis (Sokolow, 1940) in the shape of the palp and dorsal plates,. T. ussuriensis was originally described by Sokolow (1934) from the Primory Territory in the Russian Far East, and later reported from River Inôzava in Japan (Enami 1940), and from Korea (Pešić et al. 2013). Differences between T. wuyiensis and T. ussuriensis are given in Table 1.
