The family contains 193 species, although the composition of the genera is less certain, and more study is needed before the genera can become stable. [1] The currently accepted genera are Antricola, Argas, Nothoaspis, Ornithodoros, and Otobius. [1]

Nuttalliellidae can be distinguished from both ixodid and argasid ticks by a combination of a projecting gnathosoma and a soft leathery skin. Other distinguishing characteristics include the position of the stigmata [ permanent dead link ] , the lack of setae, the strongly corrugated integument, and the form of the fenestrated plates.
