Miktoniscus linearis (Patience, 1908)
GB IUCN status: Not applicable (non-native)
The pygmy woodlice of family Trichoniscidae (and Styloniscidae) are readily distinguished from other woodlice by the shape of the antennal fagellum which comprises a tapered cone (of indistinct segments) bearing a terminal bristle. All trichoniscids, except Haplophthalmus spp., have a stepped body outline.
Miktoniscus linearis is a very small, white woodlouse reaching only up to 3 mm in length. The body is strongly tuberculate and the eye composed of single black ommatidium (thus similar in appearance to the coastal M. patiencei).
Distribution and Habitat
Miktoniscus linearis was described new to science from heated glasshouses at Kew Gardens in 1908 and subsequently discovered at Berlin Botanic Gardens, Germany. In 2020 a single female specimen, possibly this species, was found under a piece of dead wood at the Eden Project (Mediterranean Biome), Cornwall.
So far this woodlouse has not been found 'in the wild' so it is not known from where it originates.
