Genus Formosania gen. nov. 

 Type Formosania gilherti Oshima. 



Body elongate, rather high, anterior part depressed; snout spatulate; 

 mouth inferior; upper lip fleshy, with a distinct inner fold; lower jaw 

 with a sharp horny edge; barbels numerous, inferior, upper jaw with 

 two transverse rows of minute barbels and one pair of thick maxillary 

 barbels, lower jaw with three pairs of small barbels; scales minute; 

 lateral line continuous; dorsal fin high, inserted in front of the origin 

 of the ventral; pectoral fin large, not reaching the ventral; the anal 

 large, when depressed reaching the root of caudal; pectoral and ventral 

 fins horizontal, one outer ray simple. 



Remarks: Well distinguished from other genera of the Ilomalop-

 barbels which are arranged in two series. 



Distribution: Formosa and China.
