[4] Protictitherium was akin to civets both in size, being around 50 cm (19 inches) tall at their shoulder; and in weight, with calculations suggesting something around 4-8 kg (8-18 lb), with differences between species.

Despite having existed for over a million years it remained fairly unchanged; specimens separated by large stretches of time possess slightly different proportions of their first molar.

Its holotype hails from the Yeni Eskihisar formation, from the late Miocene of Turkey, where it coexisted with P. crassum for at least a million years, implying some manner of niche partitioning where P. cingulatum opted for an arboreal lifestyle.

Its specific name, cingulatum, means cingulate in latin, in reference to its highly developed dental cingulum.

It seems to represent the ancestral condition of the genus, therefore it's often recovered as a common ancestor of the other species, hence its specific name intermedium, intermediate in Latin.
