Laos(Luang Prabang). Here a male. Female above is a little dirty, but same white spots an bands, same inferior lobe eyes, etc.
I think that this one is Macrochenus tonkinensis, with different white bands on face, different lobe eyes, etc.
In Breuning revision:
M.tonkinensis & M.assamensis quite similar, but:
inferior lobe eyes longer than cheek -> M.tonkinensis
inferior lobe eyes as long as cheek -> M.assamensis |

yes, I agree, maybe anybody can provide a type picture of M. assamensis (BMNH) !
features like this mentioned by Breuning are not helpful for identifications  |

In my opinion, they are female and male of M. tonkinensis.
M. assamensis is this specimen from Assam, well corresponding to these specimens.
You can read the description of tonkinensis here, p. 13 (373) |
