Styloniscus spinosus (Patience, 1907)

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.

Styloniscus spinosus has the same general appearance Styloniscus mauritiensis and as Cordioniscus stebbingi, but is slightly larger, reaching 5 mm in length.

Identification should be based on a male specimen.
