Agassiz, D.J.L.,Beavan, S.D. and Heckford, R.J., 2013
Checklist of the Lepidoptera of the British Isles, 2013
Replaces Bradley, J. D, 2000 (Checklist of Lepidoptera Recorded from the British Isles, Second Edition, revised) as the definitive British list. It introduces a novel numbering sytem whilst removing one Gelechiid species from the main list (Sophronia humerella is placed in the Questionable list) and reports that what was known as Scrobipalpa salinella in the British Isles is probably referable to S. salicorniae. The taxonomic order within the Gelechiidae is reported to have been rearranged to follow that in the Fauna Europaea (www.faunaeur.org/) but does not appear to be a direct match.
