Ceratogyrus
genus of arachnids
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.
Horn function
The horn of C. marshalli stands straight up about 1 cm in an adult.
“Ceratogyrus” enters the record as genus of arachnids. Crown Archives preserves that source wording while asking what Ceratogyrus, genus and arachnids can confirm, complicate or overturn.
Why this record matters
“Ceratogyrus” is worth following because a concise public description often conceals a longer documentary argument. Here, Ceratogyrus, genus and arachnids provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 19, 2025. The linked authority identifier is Q1813011. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
