Remarks — This species was described by Wiles (1991) on basis of two males from Selangor, Peninsular Malaysia. In the original description no information on the colour pattern of the dorsal shield was given ( Wiles 1991). Later on, T. dentifera has been reported from Wuyishan, China ( Gu et al. 2020a).

Distribution — Malaysia, China, Bhutan (this study).
