Styloniscus spinosus (Patience, 1907)


GB IUCN status: Not applicable (non-native)

ID Difficulty


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.

Distribution and Habitat

Styloniscus spinosus has been collected from inside heated glasshouses at Glasgow, Edinburgh and Kew Botanic Gardens.

In 'the wild' it is known from Mauritius, Réunion, Madagascar and Hawaii.
