This species, previously recorded in Peninsular Malaysia, has been first discovered in Thailand, before in Betong (Yala) and then in Khao Ramrome (Nakhon Si Thammarat) in July 2014 by Prasobsuk Sukkit and Yutaka Inayoshi. Not difficult to identify due to its size and if you can see the upperside, is quite different from the other common Poritia.
