''Bumba horrida'' is a medium-large species of tarantula (about ) found in northern Brazil, like the three other species in its small genus. It is thought to be rather shy, and was discovered relatively recently.

Natural history

Like all tarantulas, the horrida's ancestors diverged from a common ancestor with the normal, web-spinning spider perhaps 350 million years ago. This spider is shares its genus to the tiny () '' b. lennoni'', the John Lennon tarantula, and has many traits that imply it is closely related to '' Theraphosa blondi'' the Goliath birdeater spider, largest known extant spider speciesNew Tarantula (Not Beetle) Named After John Lennon
br />Though not particularly large—its body is about 1.3 inches (34 millimeters) wide—the newfound arachnid belongs to the same family as the dinner-plate-size Theraphosa blondi, the world's largest spider.
