Isopoda:  Woodlice and Waterlice

There are two reasonably up-to-date identification keys to the species of woodlice of Britain and Ireland; the Field Studies Council AIDGAP key by Steve Hopkin and the Linnean Society Synopsis by Oliver and Meechan.

A key to the four species of water-slater in Britain and Ireland is included in Gledhill, Sutcliffe and Williams (1993).

A distribution atlas has been published by Gregory (2009) based on records received by the BMIG Woodlouse Recording Scheme. As well as distribution maps, his book contains much useful information on woodlice habitats. Updated maps including subsequent records can be viewed via the NBN Gateway.

Diplopoda:  Millipedes

The most comprehensive identification guide to species of millipedes of Britain and Ireland is Blower’s (1985) Linnean Society Synopsis, which is sadly out of print.  

About a dozen species found in Britain and one found in Ireland are not described by Blower (1985). Most of these species have been described in the Bulletin of the British Myriapod Group and its continuation the Bulletin of the British Myriapod and Isopod Group.

Notes on name changes since the publication of Blower’s key are to found in the distribution atlas by Lee (2006).

A revision of the Linnean Society Synopsis is in preparation and will include all of the additional species. All of the British and Irish species are covered in a draft key produced by the recording scheme organiser, Paul Lee.

Chilopoda:  Centipedes

The most recent comprehensive account of the identification of British Centipedes is Barber's (2009) Linnean Society Synopsis.

A Provisional Atlas has been produced describing the distribution of Centipedes in Britain and Ireland Barber & Keay (1988) and is available online. As well as distribution maps this has an analysis of data on habitats. 

A new comprehensive distribution atlas to British Centipedes is in preparation.
