GB rarity status: Nationally Scarce
All three are small (to 4 mm) creamy-white woodlice flushed with varying amounts of orange. The dorsal surface is covered with weak tubercles and the eye is composed of a single dark red ommatidum. All eye and body pigments are rapidly lost in alcohol, thus making preserved specimens difficult to separate from Metatrichoniscoides celticus or M. leydigii.
Distribution and Habitat
It has a strong preference for semi-natural habitats with undisturbed friable calcareous soils, including short-turf grassland, rank grassland, mixed scrub and deciduous woodland.
