FIRST RECORD OF CHAETOPHILOSCIA CELLARIA (DOLLFUS, 1884) FROM THE CHANNEL ISLANDS (ISOPODA: ONISCIDEA: PHILOSCIIDAE)

The woodlouse Chaetophiloscia cellaria (Dollfus) is reported for the first time from Guernsey, Channel Islands. A brief description with illustrations is provided to enable identification and information is given about habitats and microsites inhabited and associated species. C. cellaria appears to be undergoing an expansion of range into north-west Europe and is probably a recent colonist of the Channel Islands, aided by human activity. It may be just a matter of time before it is found on the south coast of England.
