Reductoniscus costulatus Kesselyák, 1930

Status

GB IUCN status: Not applicable (non-native)

Identification

This very small woodlouse, reaching 2 mm, is capable of rolling into a sphere when disturbed.  The head and body are covered in characteristic broad rounded tubercles (confusion only likely with Buddelundiella cataractae). However, the telson of R.costulatus has a characteristic ‘hour-glass’shape (also seen in Venezillo parvus).
