This species, previously known from Java, Borneo, Sumatra, Singa- 

 pore, and Malacca, was first ascribed to the Thailand fauna in 1881 

 when it was reported from Chantabun by Sauvage. In 1927, Layang 

 Gaddi, collector for the U. S. National Museum, obtained 11 specimens 

 in the lake known as Nong Khor, Southeastern region. In April of 

 the same year Luang Masya Chitrakarn, of the Siamese Bureau of 

 Fisheries, obtained 2 specimens in a stream on Kao Sabap, and in 

 January 1929 another specimen was caught in another stream on the 

 same mountain at about 1,000 feet elevation.
