Genus of spiders
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 .
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.
