Six new beetle species have been discovered in South America by researchers at the University of Copenhagen. Among them is one with a distinctively shaped sexual organ that has led the researchers to name it after global beer powerhouse Carlsberg. According to the researchers, more attention urgently needs to be paid to our planet's millions of unknown species before it's too late.

Researchers often use the genitalia of insects to differentiate species, since they are a reliable signature of a species uniqueness. A newly discovered beetle has been found to have genitalia that look remarkably similar to a bottle opener.
