We have collected male and female Megasoma mars in Paraguay, however, scarce information from the web suggests a different distribution range. I would appreciate any information regarding this species as well as sources of information to contrast. Both specimens were found dead in forest islets and with almost five years apart when found them. I also attached two pictures in case this might be a case of wrong identification.
Thank you very much Seyed! All the sources I had checked only located the species farther North, Brazil and Colombia, but didn't mention Paraguay. Thanks again.
I have contacted a researcher specialist about this issue, and has very kindly helped me. He has indeed corrected the identification to Megasoma janus janus, and has provided with a picture for M. mars to notice the differences (mostly in the horns). M. janus is indeed distributed in Southern Brazil and Paraguay.
