PTEROCHTHONIIDAE Grandjean, 1950

Among the Enarthronota Pterochthonius angelus is remarkable by its exceptional habitus, whilst many of its characters must be regarded as unique and primitive. It is impossible to classify the species in one of the above-mentioned families, so that Grandjean (1950) created a separate family Pterochthoniidae .
