BRACHYCHTHONIIDAE Grandjean, 1947

Although the Enarthronota mainly consist of relics or isolated genera, the Brachychthoniidae still represent a branch rich in species. The group was separated as a special family from the Hypochthoniidae by Grandjean (1947). The following genera (mentioned in chronological order) are to be distinguished: Brachychthonius Berlese, 1910 (= Brachychochthonius Jacot, 1938); Eobrachychthonius Jacot, 1936; Synchthonius Van der Hammen, 1952; and Liochthonius nov. gen. (= Brachychthonius auct. non Berlese). In the Berlese Collection three of these are represented by one or more species. With some hesitation I have created here a new name for the genus Brachychthonius auct. non Berlese; many authors already pointed out that Brachychthonius Berlese and Brachychochthonius Jacot are synonyms, but up to now nobody has renamed Brachychthonius auct.

Forsslund (1957) published a revision of some of Berlese's Brachychthoniidae , so that in the following I have made only a few notes about these species.
