Mandibles with prominent preapical tooth
distinguishes Nothopleurus from Mallodon

 
I was looking at
the Smithonian photos: that prominent tooth is really much bigger in Nothopleurus. I am nearly sure also, that Eric keyed them out or compared to the UoA collection. I'll ask him to make sure.

 
the few I have agree well with

and of course the other characters in the key require a ventral view.

 
I can try and
photograph ventral aspects - what is needed? I did include the dorsal view of the open mandibels. It is very difficult to open them now.

 
see
as Mike suggested - metepisternum

compare to

hard to see, but margin appears straight

 
Metasternum
Need a shot of the metepisternum, which is straight or convex in Mallodon, concave in Nothopleurus.

 
here it is (added image)
hope it's clear enough, seems concave to me - Nothopleurus?

 
Where?
I don't see the added image.

 
here

 
Oh, right there
Sorry, I'm blind, too. I do agree that it's concave.

 
Nothopleurus madericus?
I'll make a page if you concur

 
Ok,
I have no way of getting more info from literature - I did contact a local cerambycid expert, but I think he's collecting in Guatemala (sigh) right now. So do what you feel comfortable with

 
Stenodontes lobigensis
I've found a male and two more females close to the first site. The male fits exactly with the Harvard type of S.lobigenis formerly Mallodon gnatho.

 
OK
keep an eye out for the madericus. Good series of shots.
