Lethnidae

Lethnidae (レスニデー, Resunidee), also known as Bandit Spider, is a Temnoceran.

Physiology
In general shape, Lethnidae is a large wandering spider, with ,large abdomen and body as well as long limbs, and they are covered with small hairs. In tip of each limb, there is a hook to make climbing on walls and maintaining grip from its prey easier.

Lethnidae has also some small spikes in their body, to make attaching the bones to their body easier. Lethnidae has 8 eyes, from which the right and left most ones are bigger than 6 at the center.

Much like Nerscylla, Lethnidae also possesses clawed forelimbs near head, as well powerful jaws that can extend a bit, but not nearly as much as those of Nerscylla..

Abilities
Lethnidae uses its webs to bind bones littering the Rotten Vale to it's body, giving itself an armor similar style to that of Radobaan. This slows the spiders movement down a bit, in exchange of giving it defense against predators and hunters, as well as a camoflague to hide int othe Rotten Vale.

When enraged, Lethnidae discards the bone armor temporarily. Without armor weighting it down, it becomes much more agile predator, capable of chasing it's prey down in a blink of a eye. While it's agility is near that of Apex Predator of the Rotten Vale, Odogaron, it is more vulrenable to damage without armor protecting it. After a while, Lethnidae uses it's web to re-attach bones to its body.

Lethnidae's poison has paralytic properties, thanks to its main source of food: Girros. It is also possessing resistance to Effulium of the Rotten Vale.

Habitats
Lethnidae lives mostly in the Rotten Vale of the New World, where it hunts down small monsters such as Girros, Raphinos, as well as Hornetaurs. Ocassionally it is known to take down Great Girros as well, but it leaves larger monsters such as Bazelgeuse and Odogaron alone.

Trivia
