This family has no subfamilies.^[3] The family name Ferussaciidae is from 1883 and therefore it is more recent than the family name Cecilioididae Mörch, 1864. However, the latter has been declared as a nomen oblitum because it had not been used for over 100 years. Ferussaciidae has been declared a nomen protectum.^[3]

Distribution

The distribution of Ferussaciidae includes Africa to Europe and the Near East, tropical Americas, Hawaii and tropical Asia.^[1]
