Corynis obscura

Found across Scandinavia and central Europe, rarely on the near continent. The evidence is not strong enough for it to be inferred that Britain was part of the natural range of the species. Stephens (1835) said it was 'said to have been found in Lincolnshire', with specimens in the Natural History Museum. Benson (1951) noted that the range of this species did extend north to Scandinavia and that it would not be a surprising member of the British fauna but was inclined to discard the record. A small black species with dark legs.
