Description: Can be distinguished from all congeneric species by the following unique combination of characters: (1) dorsal fin rays II + 8; anal fin rays: modally 3 + 18 = 21 ; spine of pectoral fin with posterior serrations modally 18; vertebral count usually 5 + 43–44. Colouration: Body and head entirely bright creamy yellow to golden yellow, dorsal half of head and trunk with light brown; all 4 pairs of barbels creamy white to snow white; adipose fin creamy yellow to brownish yellow; anal fin creamy yellow with lighter basal skin; and caudal fin creamy yellow with distal black margin (Chen et al. 2024). Etymology: The genus name of Tachysurus: tachys, swift; oura, tail, referring to the presumed agility of T. sinensis based on its “long and nimble” tail (translation). The specific name of flumendraco: Derived from the Latin words flumen ( = river) and draco ( = dragon), in allusion to specific local common name in Taiwanese dialect as “Ng-Gang-Ling” meaning as “Yellow River Dragon”. Remarks: The Pelteobagrus genera have in the past been distinguished by their forked caudal fins (vs. truncate/emarginate caudal fins in Pseudobagrus but most of these genera have now been moved to a new family, Tachysurus (Bogutskaya et al. 2008). |
