No records since the early 19th century, when three specimens were said to have been taken in the vicinity of London. These include the type specimen. Liston & Prous (2014) investigated this record and felt that the evidence supported the fact that it had indeed been taken in London. On balance, the evidence currently suggests it was once present but is now Regionally Extinct in Britain. However, the lack of subsequent British records could be, in part, because Benson (1951) did not include the species in his keys; could examination of specimens of P. niger conceivably reveal more examples?
