Ogoveidae

The chelicerae exhibit a smooth, robust, second segment, as well as a dorsal crest, small ventral process, and large, uniform, nodular teeth.

They can be distinguished from other families of Sternophthalmi by the smooth tarsal claws on the second tarsi, as well as a conspicuous opisthosomal median furrow, more distinct than that of some Neogoveids, and a short, thornlike, triangular adenostyle.

[1][3] Ogoveidae also possesses several unique apomorphies, including a conspicuous, posteriorly projecting apophysis associated with the sternal exocrine glands, a conspicuous, anteriorly projecting tricuspidate process located along the front of the prosomal carapace, a modified, compressed pedipalpal femur that allows the pedipalps to fold over the chelicerae, and unique structures known as Hansen's organs.

Hansen's organs appear as circular, raised, smooth patches of cuticle, and can be found on the legs, coxae and the underside of the opisthosoma.

It can be distinguished from that species on the basis of its large size, significantly shorter anterior process, and proportionally longer chelicerae, which also exhibit a much more conspicuous dorsal crest.

[3] The first species of the genus to be discovered, it is known only from a single female specimen collected along the Ogooué River in what was then French Equatorial Africa.
