A new butterfly species has been named after the 'Lord of the Rings' villain.

A large international team of researchers has identified nine groups of newly described butterflies, and one colorful genus broke the mold with its striking wing patterns. The “distinctive fused orange rings” that encircle black-and-white eyespots on the hindwings of this group led the researchers to name the genus Saurona, according to a recent study published in the journal Systematic Entomology. The researchers’ findings highlight the vastness of Earth’s biodiversity that scientists have yet to document. “What this paper shows is that there are just hundreds and hundreds of species that we don’t know yet, that haven’t been named,” said Robert Robbins, research entomologist and curator of lepidoptera at the Smithsonian National Museum of Natural History. This paper takes a very difficult and large group of butterflies, and they just amassed an immense amount of DNA information over the years and just brought it all together.
