Oxylaemus cylindricus (Creutzer in Panzer) (Bothrideridae) rediscovered in Britain

摘要

Hyman (1992) listed this beetle as Extinct (i.e. with no records since 1900), stating that it had been recorded from South Hampshire and Nottinghamshire, and that it was last recorded in the 19th century. In 2009, it was rediscovered in Britain at Ebernoe Common Sussex Wildlife Trust (SWT) reserve in the West Weald, West Sussex (VC 13), where 21 specimens were captured in two subterranean traps at the roots of veteran oaks (Telfer, 2009): the first records for Sussex. Further saproxylic survey work in the West Weald in 2010 added two further localities: The Mens SWT reserve where a male was caught in a vane trap on a beech (Telfer, 2011), and Petworth Park where a total of 23 were captured in a subterranean pitfall trap at the roots of a standing dead exotic broadleaf tree (Telfer, 2010). The subterranean pitfall traps used are based on a section of rainwater downpipe, a modified version of an original design by John Owen (1995). Details of all recent records are provided in Table 1.
