Planhoogenraadia

P. gracilis – from Bonnet, 1977

Genus Planhoogenraadia  Bonnet, 1977
  
Diagnosis: Test bilaterally symmetrical; aperture more or less covered by a visor-like extension of the dorsal surface, 2 lateral grooves at the junction of visor and belly. In contrast to Hoogenraadia ventral side always flat; this is interpreted as an adaptation to the living in soil as in Plagiopyxis or certain Centropyxis. Pseudostome usually semi-circular or elongated oval, located back into the test.

Type species: Planhoogenraadia acuta Bonnet, 1977.

Eight species.

Ecology: forest soils often on calcareous bedrock.
  
Hoogenraadia distribution

Distribution of Hoogenraadia (red), Planhoogenraadia (yellow) and Geoplagiopyxis (green) – modified after Smith et al. 2008.
