They were taken in French Guiana and are likely to be different species but I lumped them all here for brevity. Photos come from Stephane Brule Is there any chance of a tribe/sub-family?

I reared both species in Surinam. I don't know the other two. Please encourage Stephane to try to rear them! This would produce so much new information!

I am also in touch with another entomologist out there who will twist his arm ... Stephane is a coleopterist so he does understand the importance of collecting but I think his time is limited and he does all of this as a hobby.
