Sigmasoma chakratongi - Maa 1963
Photo taken at Kaeng Krachan, Phetchaburi Prov., Thailand on 29 January 2018.
This is a very rare species and there is very little information available about it.
There are, as far as I am aware, only three photographs of the species from Thailand, and I am extremely grateful to Thornthan Unnahachote for giving me permission to show his photo here.
There is one other photo, produced in the Encyclopedia of Insects by Resh & Carde (p.56). That specimen is from Vietnam (no further information given) and is clearly incorrectly labelled as a Machaerota sp.
