* The Oncopoduridae were first recognized as a distinct family by Denis in 1934, but later workers continued to refer to it as a sub-family either of the Cyphoderidae or the Isotomidae, and much confusion has resulted. Bonet in 1943, has discussed the situation at some length and produced convincing evidence to support Denis's view, with which I concur, that the Oncopoduridae is a family.
