Material examined. Holotype: ♂, mixed forest (35°30 ʹ 12 ʺ N, 126°54 ʹ 41 ʺ E, alt. 127 m), Sang-dong, Jeongeup-si , Jeollabuk-do, 14 May 2006, B. K. Seo GoogleMaps . Paratypes: 21♂♂, 1$, same data as holotype GoogleMaps .

Etymology. The specific name is a Latin noun “ subula ” (awl), referring to the shape of pointed projection of male clypeus.

Diagnosis. The new species resembles T. praecox ( Pickard-Cambridge, 1873) and T. ventosa Millidge, 1979 in the radix, embolus, and tegular apophysis of male palp, but different from the latter by the detailed shape of embolus tip and tegular apophysis, the position of copulatory opening and fertilization ducts ( Fig. 11 View Fig C-E, G-I).

Description. Male (holotype). Total length 1.56. Habitus as in Figure 5P View Fig . Carapace reddish brown, 0.90 long, 0.60 wide; cephalon elevated, with a pair of sulci behind PLE and a pointed projection at clypeus ( Fig. 11 View Fig A-B).

Abdomen oval and dark brown, and 0.84 long, 0.62 wide. Palp ( Fig. 11 View Fig C-F): tibia with a broad angular dorsal apophysis and a small angular retrolateral apophysis; tegulum well developed with a membraous apophysis; embolus short and curved; distal suprategular apophysis with small pointed projection.
