New ant species! Scientists uncover treasure trove...of ants!

New ant species: Researchers working in Central America and the Carribbean have discovered 33 previously unknown ant species.

A total of 33 previously unknown ant species have been discovered in Central America and the Caribbean. The nearly blind ants live in leaf litter and rotten logs in rainforests and are all quite tiny, each less than one-twelfth of an inch (2 millimeters) in length, according to new research.  

Scientists named about one-third of the ants after Mayan deities, said Jack Longino, an entomologist at the University of Utah, in a statement from the school.

"The new species were found mostly in small patches of forest that remain in a largely agricultural landscape, highlighting the importance of forest conservation efforts in Central America," Longino said. These crawling, chomping mini-beasts perform many vital roles in ecosystems, such as aerating soil and pollinating plants.

When viewed under a microscope, they are the "stuff of nightmares," Longino added. "Their faces are broad shields, the eyes reduced to tiny points at the edges and the fierce jaws bristling with sharp teeth. They look a little like the monster in 'Alien.'"

One of the newfound species, Eurhopalothrix zipacna, is named for a violent, crocodile-like Mayan demon, and is found in Guatemala and Honduras. Another, dubbed Eurhopalothrix xibalba, or "place of fear," refers to the Mayan underworld; this ant is found from Honduras to Costa Rica.

Scientists have so far recorded about 15,000 species of antsworldwide, according to the statement. But there may be as many as 100,000 in total, said Longino, who has now discovered 131 new species of ants, the statement noted. Insects in the tropics have astonishing levels of diversity, studies have shown.

About half of the new ants were described in a paper co-authored by Longino and published July 29 in the journal Zootaxa. The rest are detailed in a paper to be published shortly in the same journal. The ants detailed in the present study come from the genus Eurhopalothrix, known for the club-shaped hairs on their bodies. The latter insects in the forthcoming paper hail from the genus Octostruma, which means "eight swellings," referring to the ants' eight-segmented antennas, according to the release.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
