They look just as scary as funny. Utah biologists decided to name about a third of the tiny but monstrous-looking insects after ancient Mayan lords and demons.
In a recent published study, scientists announced that they identified 33 new species of predatory ants in Central America and the Caribbean.
"These new ant species are the stuff of nightmares" when viewed under a microscope, says entomologist Jack Longino, a professor of biology.
"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.' They're horrifying to look at up close. That's sort of what makes them fun."
Longino identified and named 14 new species of the ant genus Eurhopalothrix and distinguished them from 14 other previously known species.
The genus name is Greek and refers to the club-shaped hairs on many Eurhopalothrix (pronounced you-row-pal-oh-thrix) species.
"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 says.
The new ant species are less than one-twelfth to one-twenty-fifth of an inch long -- much smaller than a rice grain or common
half-inch-long household ants -- and live in the rotting wood and dead leaves that litter the forest floors in Central America.
"They are nearly eyeless and crawl around in leaf litter," using primitive compound eyes to detect light but not form images. No one knows how they find their prey, presumed to be soft-bodied insects, spiders, millipedes and centipedes.
But the ants are known to coat themselves with a thin layer of clay, believed to serve as camouflage.

Among the newly discovered and named species from forest-floor leaf litter:
-- Eurhopalothrix zipacna, named for a violent, crocodile-like Mayan demon and found in Guatemala and Honduras.
-- Eurhopalothrix xibalba, or a "place of fear," for the underworld ruled by death gods in certain Mayan mythology. It lives from Honduras to Costa Rica.
-- Eurhopalothrix hunhau, for a major Mayan death god and a lord of the underworld. This species lives in Mexico and Guatemala.
Some of the scary looking new species have more mundane names, such as Eurhopalothrix semicapillum, named for partial patches of hair on its face, and
Octostruma convallis, named after the curved groove across its face.
Longino named one species Eurhopalothrix ortizae, after Patricia Ortiz, a Costa Rican naturalist who died in a rock-fall accident this year.
The horror-show faces of some of the new species feature what is known as the labrum, which is like an upper lip, and jaws that open and close sideways
instead of up and down as teeth on the jaws clamp down on prey.
"If you really want a movie monster that freaks people out, have the jaws go side to side," Longino says.
"Ants are everywhere," Longino says. "They are one of the big elements of ecosystems, like birds and trees. They are major movers of stuff. Some act as
predators and influence the population sizes of other insects by eating them. They gather a lot of dead insects and eat them, so they are like
vultures at a microscale.
They move seeds around and have a big impact on what kind of plants grow where. They aerate soil and do a lot of excavation.
Having aerated soil is good for plants -- it lets oxygen get into the soil and water percolate through it better."
Lake In France Turns Red
This year, we have encountered the color red in places where we don't expect to see it. A while back the strange appearance
of Azov Sea stunned residents who saw how the water had turned red. The red rocks in China have also puzzled scientists for a long time.
Now, a lake in Southern France has also suddenly turned red.
An Incredible Geological Phenomena
Earth is an amazing planet and our nature is full of wonders. We have previously written about incredible singing plants.
This time we would like to focus our readers' attention on another amazing geological phenomena, namely so-called growing stones.
It is difficult to image that stones can really grow, but these stones seem to be alive!
Yangtze River In China Turns Red
We have seen on a couple of occassions how lakes and seas have suddenly turned red.
In August a lake in Southern France unexpectedly changed color and shortly before that the strange appearance of
Azov Sea stunned residents who saw how the water had turned red....
