Peter Clausen Posted August 17, 2008 Report Share Posted August 17, 2008 My parents live in Mexico and caught these in a place I can't spell or pronounce, at about 11,000 elevation. They are pretty distinctive so I'm guessing somebody out there must know what they are. I'm going to be working with my mom to create a Bugs of Mexico website.

Dynastes Posted August 18, 2008 Report Share Posted August 18, 2008 The first one is a male Golofa pizarro. The second may be a small G. pizarro or a different species in that genus. Quote Link to comment Share on other sites More sharing options...
Peter Clausen Posted August 18, 2008 Author Report Share Posted August 18, 2008 I had suggested to my mom (Lynn) that it might be a different species, but she was pretty sure it was something different and said the photo didn't really show some of the differences very well (and that the head has since fallen off). The G. pizzaro seems to have a much more impressive upper horn than my mom's specimen (which could just be a runty specimen). On the following sales site are some photos of Golofa spp. and a listing of a Mexican species called Golofa pusillus. http://www.thebugmaniac.be/onderverdelingb...IDAE/golofa.htm I then found this site with a G. pusillus photo that is more similiar to the second beetle with the short, rounded horn on the pronotum. http://www.insect-sale.com/photo.asp?photo=Golofa-pusillus and this from Mexico also (this could be the other one): http://www.insect-sale.com/photo.asp?photo=Golofa-imperialis Thanks for the lead on the genus!

Dynastes Posted August 18, 2008 Report Share Posted August 18, 2008 G.pussilus is rare and the bump on the pronotum should be upright (perpendicular to the pronotum) not forward. Quote Link to comment Share on other sites More sharing options...
Regiarbol Posted October 9, 2009 Report Share Posted October 9, 2009 Even though I am not that familiar with Golofa, I think it might be Golofa Pizzaro. Quote Link to comment Share on other sites More sharing options...
