A species very closely related to Rhaphuma pseudominuta Gressitt & Rondon, 1970 from Laos. I do not know if it may be considered as the same species.
In the next days I will insert a picture.

No, the elytra have analogue pattern, but the pronotum should have only two longitudinal bands.
Could you check if the femora are longitudinally ridged as Derolus-species?

All of the femurs without any ridges.

mmmhm... the single central spot on the pronotum might derive from two parenthesis-shaped spots anteriorly fused together.
This is rather typical of the species of the group histrio (sub-genus Arcyphorus Chevrolat, 1863), in Indochina with diana and patkaina. Nonetheless, a ridge is always visible on the ventral side of the middle femurs.

Sorry, Francesco, your right absolutely! But, that ridges is visible on the lateral side of the middle femurs!
It`s not like Derolus, but this does not take out of me responsibility for carelessness! Sorry. %)

No, Max, it is my fault. I was unclear since I had not reviewed the descriptions but I quoted from my memory... sorry!

I have got a R. diana in my collection; I will insert a picture in the next days... unfortunately, very far from your beautiful photo!
