The legs, tail and chelicerae of H. bicolor are paler than the carapace, forming a marked color contrast.

[1] The overall appearance is consistent with that of the other members of Hadogenes, the body construction is flattened which allows them to navigate safely in and out the cracks and crevices that comprise their habitats.

[2] Hadogenes bicolor is endemic to Mpumalanga and Limpopo provinces, South Africa.

It lives in crevices in dolerite and granite rocks in areas with an annual rainfall of 600–1,100 millimetres (24–43 in).

[1] Hadogenes bicolor was first described by W. F. Purcell in 1899, based on material collected by the Reverend J. W. Daneel "about twenty miles east of Pietersburg [now Polokwane], Zoutpansberg Distr., Transvaal".
