available figures they are different from the form described in this 

 paper as shown by the position and arrangement of the papillae on 

 the tail of male, although the number of papillae in these two species 

 correspond to those in S. chinensis. The terminal portion of the 

 male tail in S. acutissima is quite different from that of S. chinensis 

 although the number of pre and postanal papillae are identical. 

 While the terminal portion of the tail in S. similis resembles that of 

 S. cMnensis the arrangement and position of the papillae in the two 

 species are different.
