“…Among the three genera of mahseers, the genus Tor ( Figure 1 ) has been considered the “true mahseers” based on the morphological structure of the median lobe present in this genus but not in the other two genera [ 1 , 3 ]. Although 24 Tor species were recorded previously [ 1 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ], a recent report in Eschmeyer’s Catalog of Fishes 2021 (as of 1 March 2021) shows that only 17 out of 24 species are validated as Tor species ( Table 1 ) [ 32 ]. A recent review by Pinder et al (2019) has concluded that there are 16 valid species of Tor, and all these species have been listed in the IUCN Red List of Threatened Species TM (Version 2018-2) [ 3 ].…”

“…Nonetheless, due to locality, environment adaptation, and genetic variation, Tor species have undergone phenotypic changes [ 2 , 13 ]. In SE Asia alone, 13 Tor species have been reported [ 1 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Phenotypic variation has caused instability and confusion for Tor species speciation in the SE Asian region [ 13 ].…”

The king of rivers or mahseer comprises three genera: Tor, Neolissochilus, and Naziritor, under the Cyprinidae family. The Tor genus has been classified as the true mahseer due to the presence of a median lobe among the three genera. The Tor species are widely distributed across Southeast (SE) Asia, and 13 Tor species have been reported previously: Tor ater, Tor dongnaiensis, Tor douronensis, Tor laterivittatus, Tor mosal, Tor mekongensis, Tor putitora, Tor sinensis, Tor soro, Tor tambra, Tor tambroides, Tor tor and Tor yingjiangensis. However, the exact number of valid Tor species remains debatable. Different and unstandardized approaches of applying genetic markers in taxonomic identification and morphology variation within the same species have further widened the gap and ameliorated the instability of Tor species taxonomy. Therefore, synchronized and strategized research among Tor species researchers is urgently required to improve and fill the knowledge gap. This review is a current update of SE Asia’s Tor species, outlining their distribution, morphology, and genetic identification. In addition, the present review proposes that there are ten valid Tor species in the SE Asian region. This list will serve as a template and standard to improve the taxonomy of the SE Asian Tor species, which could serve as a basis to open new directions in Tor research.
