The Roughback Whipray Fluvitrygon kittipongi is a stingray species listed as “Endangered” according to the updated IUCN Red List. Until the year 2021, F. kittipongi was only known from five rivers in Southeast Asia, namely: Maekhlong and Chao Phraya River in Thailand, Pawan and Kapuas River in Borneo, Indonesia, and Musi River in Sumatra, Indonesia. It has been stated that this species also occurs in Perak River, Peninsular Malaysia, but without photographic records and an accurate confirmation of this occurrence. The most recent assessment (2021) by the IUCN Red List confirmed the occurrence of the species in Peninsular Malaysia based on one genetically identified specimen from the Perak River. However, the authors who evaluated this species for the IUCN Red List only stated that F. kittipongi was genetically identified, did not presenting any evidence (e.g., photographs, voucher number, a diagnosis or brief description of the specimen) or clear methodological information for the accurately identification of this unique specimen from Peninsular Malaysia. In this paper, we report a second locality for F. kittipongi in the region, providing photographs and a brief morphological description as evidence to confirm its occurrence. It is the first photographic record of this species for the region. This new record is based on two collected specimens, examined and photographed on 20 January 2019 from the Pahang River, Kuala Lipis, Peninsular Malaysia. The identification of this species confirms its presence in a new river basin, more than 150 km east from its previous record, in Peninsular Malaysia.
