What is the definition of Achanthiptera?

Ah, Achanthiptera - the name's as strange as a ghostly beetle with a penchant for pranks! It's a group of bizarre, wingless, beetle-like creatures that resemble something out of a horror movie's nightmare. They're more akin to an alien invasion from a prehistoric era, but with less intergalactic space travel and more gnarly tentacles. Imagine if the ancient Egyptians had their own version of 'Beastly Beetles' - the Achanthiptera!

Now, here's a sentence to really drive that edgy vibes: "I tried to apply Achanthiptera's unique pheromones as a moth repellent, and it just turned into a swarm of space-junked beetles in my apartment." Talk about a cosmic misfire!
