NOTES ON XESTIA ALPICOLA SSP. ATLANTICA NOV. ON THE FAROES
113
view this presence of elements from both
adjacent a/p/co/a-populations in the Faroe
race are suggestive of a clinal variation
through the entire area. At the present stage
of knowledge the small Faroe material does
not permit any definite conclusions with re-
gard to this important question. Until more
material has been collected it seems most
appropriate to maintain the isolated and de-
viating Faroe population as a subspecies
like the distinctive geometrid moth Eupi-
thecia nanata zebrata (Wolff, 1929).
Acknowledgements
The author wants to thank his friends, Mr. Peter Gjel-
strup from the Museum of Natural History in Aarhus,
specialist in soil invertebrates, for good companionship
during the field work on the Faroes, Mr. Mike Penning-
ton, Baltasound on Unst, Shetland for valuable informa-
tion on Xestia alpicola in Shetland and the Orkney Isles,
and Professor, Dr. Niels Peder Kristensen, The Zoologi-
cal Museum in Copenhagen (ZMUC) for providing
access to study material of the species. A cordial
acknowledgement is also extended to those persons who
have been willing to cooperate with the author on the
five light traps which have been in function on the Faroe
Isles during the period 1990-1996: the crew on the
Akraberg lighthouse and Mr. Eiler Djurhuus in Trongis-
vágur, Suðuroy, Mr. Ola Jákup úr Dímun, Stóra Dímun,
Mr. Oskar Oskarsson and Mr. Johannes Sørensen, Sand-
ur on Sandoy, Mr. Jens-Kjeld Jensen, Nólsoy, Mr. Hav-
grímur Gaasedal and Mr. Tróndur G. Leivsson, Tórs-
havn, Mr. Atli Vilhelm on Kunoy and Mrs. Jenny and
Mr. Selmar Lydersen, Viðareiði on Viðoy. The main
study has been made possible by financial support and
grants from Schiøtz-Christensens mindelegat, The
Museum of Natural History in Aarhus, The University
of Aarhus and The Carlsberg Foundation. Generous
support and excellent working facilities throughout the
years have also been given by Føroya Náttúrugripasavn
in Tórshavn through the past director, the late Dr.
Jóhannes Jóhansen, and its present director, Dr. Dorete
Bloch.
