N. rivularis sinta ssp. n. 



(PI. 2, fig. 21) 



In both sexes the most obvious distinguishing character is that the fore wing postdiscal spot 

 in space 2 is always much smaller than the spot in space 3, and may be almost obsolete in 

 poorly marked examples. The fore wing postdiscal and hind wing discal bands are narrower 

 than the average of ssp. magnata, more resembling ssp. insularum, but unlike the latter the cell 

 streak is quite prominent. On the under surface the ground colour is very dark brownish red, 

 as dark or darker than the darkest examples of ssp. insularum, and the hind wing subbasal 

 streak is inconspicuous.

A few examples of this most poorly marked subspecies, in which the fore wing 

 submarginal markings and hind wing postdiscal band are almost obsolete, are 

 recorded by Seok from Korea as a distinct species occurring together with ssp. 

 coreana Nakahara & Esaki, which has the white markings more strongly developed 

 than in any other subspecies. It may be that it, with ssp. kusnetzovi Kurentzov, 

 forms a duplex species with N. pryeri, but I prefer to treat it as a northerly subspecies 

 which has recently entered Korea to establish a zone of contact with the native 

 ssp. coreana.
