Also this variety differs from R. lateristriata Blkr. and equals 

 R. lateristriata sumatrana Blkr. in the generally lesser number 

 of scales in the lateral line, which is 24 29. Its coloration 

 is distinguished by a roundish, large black patch below the 

 dorsal and by a smaller one before caudal, both are united 

 by a bluish black line only. In few cases a diffuse pigmentation 

 indicates faintly the black band of R. lateristriata Blkr.
