MYRIAPODA CHILOPODA (CENTIPEDES)
The provisional atlas for centipedes (Barber & Keay,1988) maps 41 British species, regards three previously recorded types as doubtful and refers to five from buildings and hothouses. Since then a further six “outdoor” ones have been added; one doubtful (Lithobius tenebrosus) has now been recorded from Wales, one glasshouse form (L. lapidicola) has been found on the south-east coasts, one species (Geophilus carpophagus) has been split into two (G. carpophagus and G. easoni), two new species have been described (Arenophilus peregrinus and Nothogeophilus turki) and a Scottish record made of Lithobius lucifugus. In addition three further hothouse species have been recorded (from the Eden Project). For Cornwall and the Isles of Scilly a total of 31 species have been recorded in recent years of which one, Lithobius crassipes from The Lizard remains enigmatic since it has never been recorded otherwise in Devon and Cornwall and voucher specimens are not available. Two further species that had been recorded from Cornwall in the past, Lithobius agilis and Lithobius tenebrosus are of somewhat doubtful status and unfortunately the specimens are no longer available for examination. The discovery of further species from the region may be anticipated. Identification of centipedes is by an Aidgap key and a Linnean Society Synopsis (Barber, 2008 and 2009). No species were included in the original UK Biodiversity Steering Group “long list” although several had been listed in the appropriate invertebrate Red Data Book (Bratton, 1991). One species that occurs in Cornwall has been added to the UK list of Priority Species and Habitats (BAP Priority list) in 2007: Nothogeophilus turki. The following may be considered of importance specifically for Cornwall and the Isles of Scilly.
