Salmo formosanus belongs to the subgenus Trutia L., including 

 the river trout. Two forms related to it have been described by 

 Bleeker from China, the exact locality not known; these are Salmo 

 leptosoma and Salmo pomotops Bleeker in his paper, *'Sur quelques 

 especes inedites on peu connus de poissons de Chine appartenant 

 au Museum de Hambourg." Verh. Akad. Amsterdam, XVIII, 187a, 

 pp. 14, 15. 



All their species are also more or less closely related to the European 

 brook trout {Salmo trutta = S. fario) . Salmo leptosoma has perhaps 

 a slenderer body than S. saramao, and Salmo pomatops has a black 

 spot or ocellus on the opercle.
