Ceratogyrus

Ceratogyrus is a genus of tarantulas found in southern Africa. They are commonly called horned baboons for the foveal horn found on the peltidium in some species.

== Diagnosis == They are readily distinguished from other African theraphosid genera by the combined presence of a retrolateral cheliceral scopula, composed of plumose, stridulatory setae, and the strongly procurved fovea. The fovea is typically strongly procurved and in some species surrounds a distinct protuberance. This protuberance may take the form of a simple posterior extension of the caput, a low-set plug or a prominent, discrete conical projection. All Ceratogyrus species possess a pale yellow anteriorly placed, transverse, sub-abdominal band. This feature is not distinct in other Harpatirinae except Augacephalus junodi. The absence of dense, ventral femoral fringes on the palpi and legs I and II distinguish Ceratogyrus spp. from female A. junodi.
