Abstract
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.
Resumo
A arraia chicote de dorso áspero Fluvitrygon kittipongi é uma espécie listada como “Em perigo”, de acordo com a Lista Vermelha da IUCN. Até o ano de 2021, F. kittipongi era conhecida apenas em cinco rios do Sudeste Asiático: Rio Maekhlong e Rio Chao Phraya na Tailândia, Rio Pawan e Kapuas em Bornéu, Indonésia, e Rio Musi na Sumatra, Indonésia. Existem evidências que esta espécie também ocorre no rio Perak, Península da Malásia, mas sem registros fotográficos e uma confirmação precisa dessa ocorrência. A mais recente avaliação (2021) da Lista Vermelha da IUCN disponível confirmou a ocorrência da espécie na Península da Malásia com base em um espécime geneticamente identificado do rio Perak. No entanto, os autores que avaliaram essas espécies para a lista vermelha da IUCN apenas afirmaram que F. kittipongi foi identificada geneticamente, não apresentando qualquer evidência (por exemplo, fotografias, número de comprovante, uma diagnose ou breve descrição do espécime) ou informações metodológicas claras para a identificação precisa deste espécime único da Península da Malásia. Neste artigo, relatamos uma segunda localidade para F. kittipongi na Península da Malásia, fornecendo fotografias e uma breve descrição morfológica como evidência para confirmar sua ocorrência. Este é o primeiro registro fotográfico dessa espécie para a região. Este novo registro é baseado em dois espécimes coletados, examinados e fotografados em 20 de janeiro de 2019 no Rio Pahang, Kuala Lipis, Península da Malásia. A identificação desta espécie confirma sua presença em uma nova bacia hidrográfica, a mais de 150 km a leste de seu registro anterior, na Península da Malásia.
