Morphology.

Male. General features. Idiosoma elongated; frontal platelets anteriorly bulging (Figs 2A, 7B); Cxgl-4 subapical; medial suture line of Cx-II+III relatively long; posterior suture line of Cx-IV weakly curved; excretory pore and Vgl-2 on the line of primary sclerotization near posterior idiosoma margin; ejaculatory complex conventional in shape (Fig. 2D); gnathosoma ventral margin only slightly curved, rostrum well developed (Fig. 2E); P-2 shorter than P-4, ventral margin with a fine denticulation also in proximal half of the segment, distally with a laterally compressed, anteriorly directed hyaline extension; P-3 with a subrectangular, apically serrated ventrodistal projection with a fine denticles; P-4 with long and broadly rounded distal seta (Fig. 2C), ventral tubercles well developed and separated.

Measurements. Idiosoma (ventral view: Fig. 2B) L 591, W 341; dorsal shield (Figs 2A, 7B) L 472, W 305, L/W ratio 1.55; dorsal plate L 434; shoulder plate L 141-144, W 37-40, L/W ratio 3.6-3.8; frontal plate L 101-108, W 47-48, L/W ratio 2.2-2.3; shoulder/frontal plate L ratio 1.3-1.4. Gnathosomal bay L 81, Cx-I total L 200, Cx-I mL 117, Cx-II+III mL 113; ratio Cx-I L/Cx-II+III mL 1.8; Cx-I mL/Cx-II+III mL 1.04. Genital field L/W 113/95, ratio 1.19; ejaculatory complex L 166; distance genital field-excretory pore 133, genital field-caudal idiosoma margin 161. Gnathosoma vL 247; palp total L 226, dL: P-1, 22; P-2, 62; P-3, 48; P-4, 77; P-5, 17; P-2/P-4 ratio 0.8.

Remarks.

The single male specimen examined fits the original description of Torrenticola dentifera,which was based on two male specimens from Selangor, Peninsular Malaysia (Wiles 1991). The only differences are found in larger dimensions of idiosoma and palps of the South Korea specimen.

Habitat.

A permanent sandy/bouldary stream, shaded by riparian vegetation (Fig. 14B).

Distribution.

Malaysia (Wiles 1991, 1997). New for the fauna of Korea.
