Holotype male (SMF), WEST MALAYSIA , Pahang State, Fraser’s Hill , Jerian Waterfall, 3°43’26.07”N 101°42’36.22”E, 1040 m a.s.l., disturbed primary forest, leaf litter, sifting, at day; 18.VI.2013; P. Jäger leg. Paratypes . 2 Males (SMF), collected together with the holotype.

Etymology. The specific epithet, a name in apposition, refers to the terra typica of the new species.

Diagnosis. The new species is most similar to the Southeast Asian T. hamata Tanasevitch, 2014 , but can be distinguished by the notched inner edge of the proximal outgrowth of the cymbium, as well as by the presence of a deep notch on the peculiarly curved terminal apophysis.

Description. Male paratype. Small “micronetine”, total length 1.50. Carapace unmodified, 0.63 long, 0.53 wide, pale brown. Chelicerae 0.18 long. Legs yellow, proximal and distal parts of tibiae darkened. Leg I, 2.60 long (0.68+0.17+0.68+0.69+0.38), IV, 2.45 long (0.66+0.15+0.63+0.65+0.36). Chaetotaxy: TiI: 2-1-0-0, II-IV: 2-0-0-0; MtI-IV: 0-0-0-0. TmI 0.16. Metatarsi IV without trichobothrium. Palp ( Figs 54–59 ): Palpal tibia slightly elongated. Cymbium strongly modified, its proximal outgrowth thick and long, bent at right angle and forming a hook-shaped structure. Paracymbium toothless. Lamella characteristica totally reduced. Terminal apophysis very large, peculiar in shape, superficially like a lamella characteristica. Embolus with Fickert’s gland inside, thumb present. Abdomen 0.83 long, 0.45 wide, pale, darkened in anterior and posterior parts.

Female. Unknown.

Distribution. Only known from the type locality in West Malaysia.
