The new species, sporting the extremely catchy name of Paratropis tuxtlesis, is able to hide itself from predators (that would no doubt include terrified humans) as well as its prey (possibly or possibly not humans).
The guerilla spider covers itself with dust and soil particles from wherever it happens to be hiding, effectively turning it invisible.
This thin coating allows it to blend in with its surroundings and pounce on anything (or anyone) whenever it likes.
Oh and its eyes are raised higher up than normal spiders and they grow up to four inches long. Brilliant.
The good news in this horrifying situation is that the spider was discovered in Mexico, so its unlikely you'll have one living in the loft in your house.

Researchers in the National Autonomous University of Mexico (UNAM) hailed the discovery of the species as a sensation.
They said: "It is distinguished from other species because it has rough skin, like scales, that are used by the animal to attract floor particles which in turn give it perfect camouflage.
"In order to make sure its vision is not obstructed by its camouflage of dirt, the spider has eyes that are raised up higher than usual so that it can see over the covering."
The spiders can reportedly only be seen once they move – meaning they could be sitting there and you would have no idea.
