Anidorus sanguinolentus （Kiesenwetter, 1861）（Aderidae） new to Britain

摘要

In June 2020 we found a single female specimen (Fig. 1) of this aderid at a site near Gravesend in Kent (TQ610757, VC 16 West Kent). The specimen was beaten from an area of hawthorn-dominated scrub surrounded by reedbed and marshy grassland. CU provisionally identified the beetle as Anidorus sanguinolentus (Kiesenwetter), a rather unmistakeable aderid, and this was later confirmed by Dmitry Telnov via Max Barclay (both Natural History Museum, London). This represents a new genus and species to the UK fauna.
