TRHYPOCHTHONIIDAE Willmann, 1931

At first (Berlese, 1896b) Hypochthonius tectorum Berlese (1896) was classified with the Nothridae, later (Berlese, 1910) is was considered one of the representatives of the family Hypochthoniidae . Willmann (1931) created the Trhypochthoniinae, a subfamily of the Hypochthoniidae, which afterwards has been regarded as a separate family; it is related to the Malaconothridae .

Berlese's species are classified here with the genera Trhypochthonius Berlese. Trhypochthoniellus Willmann, and Allonothrus Van der Hammen 1).

1) Knülle (1957, p. 150) created a separate family Trhypochthoniellidae, because the genus Trhypochthoniellus differs from Trhypochthonius as well as from the Malaconothridae . Recently (Van der Hammen, 1955, 1955a), while dealing with the genera Archegozetes and Allonothrus, I demonstrated, however, that it is difficult to divide the family Trhypochthoniidae .
