Distribution

Malaysia (Wiles 1991, 1997), Korea (Pešić et al. 2013), China (new record).

Habitat

Streamlet.

Remarks

The Chinese specimens well fit with the original description of Torrenticola dentifera Wiles, 1991, described from Malaysia (Wiles 1991), and later reported from Korea (Pešić et al. 2013). The only

difference is the specimens from Malaysia and Korea have one large blunt spine at dorsodistal extremity of P-4, but absent in Chinese specimens.
