Pamphobeteus is a genus of tarantulas that was first described by Reginald Innes Pocock in 1901.[2] It includes some of the largest spiders in the world. They are found in South America, including the countries of Peru, Bolivia, Ecuador, Brazil , Colombia and Panama.

Diagnosis

The males of the Pamphobeteus genus have a spoon shaped or thin embolus in the palpal bulb with elongate retrolateral superior and apical keels. They also possess a tibial apophysis with two branches on the first pair of legs, the metatarsus of which closes between the two branches. Females can be distinguished from most genera (except Xenesthis and Longilyra), by the large fused base of the spermathecae and short receptacles, and differs from those two genera by the presence of only ventral metatarsal scopulae on leg IV, and absence of lyriform stridulatory setae respectively.[3]
