The specific iiume was applied in allusion to the nearly uniform 

 velvety black of the body and most of the fins and the bright orange 

 of the caudal and pectoral fins, making a very striking coloration. 

 In alcohol and formalin the general color becomes reddish brown, 

 and there appears on the side above the pectoral fin a round black 

 spot, smaller than the eye, of which there was little or no evidence in 

 life; one or two smaller black spots may sometimes appear below 

 the other. 



The vernacular name given to the fish in the upper Menam Chao 

 Phya is fla song kruang (full-dress fish). Another popular name in 

 Bung Borapet is pla Imng deng (red-tail fish) .

 Mun Kiver at Tha Chang, east of Korat, Eastern Thailand, this fish 

 appears to be familiar to the local fishermen, who know it by the 

 distinctive name of pla soi lord (tubular schoolfish) . The large black 

 dorsal, anal, and ventral fins with sharply defined white edge and the 

 long white caudal fin serve to make the recognition of this species 

 easy.
