Can anybody help with determination?

1. photo: mainly Dorysthenes granulosus. First line, first from the right side and second line, third from the right side are different Dorysthenes. Somebody told me, it could be Dorysthenes huegeli or D. buqueti.



2. photo: detail of the third Dorysthenes from right from the first row (bigger, cca 3,9 cm long) and detail of one piece of small one (cca 2,8 cm long).

I don't konow Laos beetles, but those are amazing

12-16 Scarabeidae

Thank You Pierpaolo

12 - 16 are Xylotrupes gideon (probably). Do You know some literature of the genus Dorysthenes? Especially some key?
