L of palp: P-1, 22; P-2, 66; P-3, 48; P-4, 81; P-5, 13. L of leg segments: I-L-1–6: 25, 55, 51, 67, 79, 85; II-L-1–6: 25, 49, 50, 58, 64, 75; III-L-1–6: 27, 58, 51, 72, 80, 77; IV-L-1–6: 91, 74, 85, 102, 101, 99.
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.
