First record of Longnose marbled whipray Fluvitrygon oxyrhyncha (Sauvage, 1878) (Myliobatiformes: Dasyatidae) in Malaysian waters

Abstract

An individual of Longnose marbled whipray Fluvitrygon oxyrhyncha (Sauvage, 1878) (60 cm of total length) was caught and photographed on 3 August 2020, from Pahang River, Kuala Lipis District, Pahang, Malaysia. This rare finding represents the first-ever known record of F. oxyrhyncha in Malaysian waters, and only the fourth record in Southeast Asia besides former records of F. oxyrhyncha from Thailand, Cambodia, and Indonesia. Further study and monitoring is needed to asses the possibility of the importance of Pahang River as habitat of F. oxyrhyncha.

One new Locality for the endangered species Roughback Whipray Fluvitrygon kittipongi (Vidthayanon & Roberts 2005) (Myliobatiformes: Dasyatidae) in Peninsular Malaysia, based on photographs = UMA NOVA LOCALIDADE PARA A ESPÉCIE AMEAÇADA DE EXTINÇÃO ARRAIA CHICOTE DE DORSO ÁSPERO FLUVITRYGON KITTIPONGI (VIDTHAYANON & ROBERTS 2005) (MYLIOBATIFORMES: DASYATIDAE) NA PENÍNSULA DA MALÁSIA, BASEADO EM FOTOGRAFIAS

“…In addition to Malaysia, this species is officially registered to two other countries: Thailand and Indonesia (Last et al 2010;Vidthayanon & Roberts 2005;Iqbal et al 2018). Among other biological topics, the new record of a rare non-marine elasmobranch is an important contribution to raise an understanding on the biogeography and species diversity of the Southeast Asian region (Hasan & Widodo 2020;Hasan & Islam 2020;Hasan et al 2021). As reported in this paper, the new photographic record of F. kittipongi will contribute to improve the knowledge related to geographic distribution of the species.…”

Advancing DNA Barcoding to Elucidate Elasmobranch Biodiversity in Malaysian Waters

“…The combined records from various studies had excluded species that were unaccepted in World Register of Marine Species (WORMS) ( Cephaloscyllium circulopullum and Narcine indica ) and species that had been verified as absent from Malaysian waters ( Brevitrygon walga and B. imbricata in Last et al [ 13 ]). These records have been improved in terms of classification within the family Dasyatidae [ 13 ]; incorporation of the revision of Telatrygon species in Malaysian waters [ 14 ]; delimitation of cryptic species in Neotrygon kuhlii complexes [ 15 , 74 , 76 ]; new recorded species in Malaysian water, including Carcharhinus tjutjot [ 10 ], Fluvitrygon kittipongi, and F. oxyrhyncha [ 16 , 17 ]); and Scoliodon laticaudus [ 35 ] (previously revised as S. macrorhynchos in Last et al [ 6 ]).…”

“…Within the SEA region, Malaysia is one of the top countries with rich biodiversity of elasmobranch species. To date, there are at least 70 species (19 families) of sharks and 91 species (11 families) of batoids that have been reported to occur in Malaysian waters ( Supplementary Materials Table S1 ) [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. Although new species are continuously discovered, the populations of sharks and batoids have gradually decreased over the past decades [ 18 ].…”

“…Terutama pemahaman spesies biogeografi dan keanekaragaman (Hasan et al, 2021a). Selain itu Adanya penelitian biodiversitas ikan sangat penting untuk program konservasi, seperti domestikasi, pengembangan yang berkelanjutan mendukung sistem sosio-ekologis dan pemahaman terhadap keragaman spesies dan penyebarannya (Hasan et al, 2022;Hasan & Islam, 2020;Hasan et al, 2021b).…”
