SPHAEROCHTHONIIDAE Grandjean, 1947

In his 1932 ad 1934 papers, Grandjean still classified the genus Sphaerochthonius with the Hypochthoniidae, although he stated a relationship with the Protoplophoridae . Later (Grandjean, 1947) he created a separate family Sphaerochthoniidae, consisting of the genus Sphaerochthonius only; the same conception is found in his 1954 classification.
