Dolerus vestigialis (KLUG, 1818)

All these Highland specimens have very black legs. At least in S. Scotland, normal red-legged forms also occur. Benson (1934) was misled by a pair of dark specimens from Killin and misidentified them as D. genucinctus Zaddach, 1859 , a species that does not occur in the British Isles, as far as is known.
