The curious looking Golofa claviger

[Trehopr1]

For the beetle enthusiasts I present this most curious
looking of Dynastine species. Most specimens of Golofa
claviger seem to be from Peru or Ecuador. It is considered
a pest species amongst oil palm plantations in Brazil.

Males of this uniquely ornate species possess a highly-arched
3-pronged umbella shaped "overhang" above their head. It is
basically this exaggerated pronotum for which its subfamily
is best known. Located on the head of this species is yet
another long, tapering, and recurved horn which it uses in
leverage jousts (with other males) or perhaps to peel back
the outer skin of fleshy fruits.

In short, it is an amazing looking creature to behold for its
strange and inexplicable appearance. There are some other
rather odd dynastines worthy of mention as well but, G. claviger
is surely amongst the few at the zenith of eccentricity !

I have a 45 YO pair of Golapha pizarro. Looks the same as claviger to me.

Hi Chuck,
Yes, I have seen the name G. pizzaro used.
I do not know if both are distinct species or if one name is synonymous with the other and is (just an older one).

I'm no expert on this group --- just an avid admirer so, perhaps an inquisitive beetle enthusiast can enlighten us as to the differences (if there are any) between the two.
