Genus Acratia Delo, 1930

Acratia sp. A aff. sp. 42 sensu Braun (1967) ( Fig. 4L).—We compare Acratia sp. A to Acratia sp. 42 figured by Braun (1967: pl. 3) from the Great Slave Lake region ( Canada).

Acratia . sp. B aff. sp. 271 sensu Braun (1967) ( Fig. 4M, N).—A second species of Acratia is close to the Acratia sp. 271 figured from northeastern Alberta ( Canada) by Braun (1967: pl. 3). This species were previously recognized in the Late Frasnian of the Devils Gate section ( Casier and Lethiers 1998a).

Acratia sp. C aff. 274 sensu Braun (1967) ( Fig. 4O).—Some carapaces of Acratia may be close to Acratia sp. 274 figured from the Great Slave Lake region ( Canada) by Braun (1967: pl. 4).

Acratia sp. D aff. A. paraschelonica Lethiers, 1974 .— A poorly preserved carapace of Podocopina in the lower part of the Frasnian (sample DVG−03−6) presents some affinity with Acratia parachelonica Lethiers, 1974 , from the Late Frasnian of Belgium.
