The Ecuadorean olinguito may be the first new carnivorous mammal to be found in the Americas in 35 years, but if the categories are widened a bit, you can find lots of cute critters that have been added to the tree of life in recent years.

For example, there's the lesula — a shy, big-eyed monkey that was described as a new primate species in September. The discoverers saw it just a few years ago in the Democratic Republic of the Congo. It went unnoticed for so long because it's found only in a dense, dark, isolated swath of rain forest that's seldom visited by scientists.

Then there's Durrell's vontsira, which was first spotted by researchers in 2004 while it was swimming in a lake, and was described as a new species in 2010. The mongoose-like mammal is found only on the island of Madagascar, and its range is so limited that it's considered "one of the most threatened" carnivores in the world, according to Conservation International.

Because of its isolation, Madagascar is a hotbed for biodiversity and novel species: The island is home to a soulful-looking lemur that was described as a potentially new primate species in 2010. Just last month, researchers identified another new species in Madagascar known as the Lavasoa dwarf lemur.

In the big picture, the olinguito is just one pretty face among thousands of new species. Arizona State University's International Institute for Species Exploration estimates that about 18,000 species are added to the master list every year. That averages out to almost 50 new species a day.

Quentin Wheeler is the institute's founding director and the author of a recently published book on recently discovered species, titled "What on Earth?" He says it's thought that our planet is home to 10 million to 12 million living species, but we've cataloged only about 2 million of them. And that's not even counting the legions of microbial species that live among us (and in us).

Time is running out for many of those species — due to habitat loss and other threats to biodiversity — and Wheeler says it's time to pick up the pace. "We are calling for a NASA-like mission to discover 10 million species in the next 50 years," he said in a news release. "This would lead to discovering countless options for a more sustainable future while securing evidence of the origins of the biosphere."
