Comments. The specimen from Chiang Mai differs slightly from the other by the larger size, the larger areolae, the discoidal area wider (5 areolae wide), the paranota are not open inwards but closed. The specimens from the Tiger project are much darker, although they have the same habitus than the others. This species was previously known only from China (Hong Kong) (Drake 1927b).
