China, Japan, Korea. Though my specimens are all small Garman 

 says "larger examples with tubercles on the middle of the back above 

 the shoulder girdle, and more advanced stages with a vertebral row 

 of backward-directed tubercles from the back of the head, largest 

 on the base of the tail in front of the caudal spine and with a parallel 

 row on each shoulder.'' Miiller and Henle's figure shows two caudal 

 spines and row of seven vertebral spines at front of back.
