This terrifying monster from hell is just one of seven newly-discovered wasp species discussed in a new paper published in Zootaxa, but it's certainly the most bizarre find. That's not too much of a surprise, however, considering how little we know about these sorts of creatures, and how rapidly we're stumbling on more and more of them. "Amazonian parasitoid wasps are largely unknown," says Ilari Sääksjärvi, a professor of biodiversity at the University of Turku in Finland and a coauthor of the new study. "I have studied Amazonian parasitoid wasps since 1998, and have found hundreds of new species, along with describing and naming about 150 of them. The Amazonian parasitoid wasp fauna is extremely diverse."
