This species has been recorded only from Malaysia (Cheng et al. 2001). Therefore, this is the first record of this species species in Thailand. In this study, this species was collected from the northern (Uthai Thani province), central (Kanchanaburi and Phetchaburi provinces) regions. Thus, in Thailand, it is restricted to the Isthmus of Kra. This species was found in similar mesohabitats to the of its congener. However, many adults were found striding rapidly in an upstream direction in streams associated waterfalls in southern Thailand.
