Styloniscus spinosus (Patience, 1907)
GB IUCN status: Not applicable (non-native)
The pygmy woodlice of family Styloniscidae (and Trichoniscidae) 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.
Identification should be based on a male specimen.
