Concerning Halora fes repro bus
(O.P. Cambridge) (Araneae, Erigonidae)
occurrence in Scandinavia
By H a n s K a u r i, Zoological Rluseum, University of Bergen
In a recently published article Tambs-Lyche (1964) announces
an interesting find of Halorates reProbus from Norway. That
same article contains a map showing the entire distribution area
of the species. As that map, however, does not cover all Scandinavian
records it might be of certain interest to con~plete the
outlined distribution. Halorates reProbus was found in Sweden
in 1940 and 1942. The specimens1 were collected by Dr. Backlund
and the records were published 1945. The specimens occurred
in July and August during investigation of wrack beds at
Barseback on the coast of Oresund and at Kivik on the Baltic.
The author of these lines later (1948) also found the species near
Skanor (on Oresund) south of Barseback (unpublished). From
ecological point of view is the occurrence of the species on the
coast of the brackish basins of Oresund and the Baltic of some
importance. The record from Kivik is the easternmost of the
distribution.
Thus Halorates reProbus is distributed more widely inside
Scandinavia and penetrates into the southwestern part of the
Baltic coast. The eco-zoogeographical type of distribution is
appearently atlantic, which Tambs-Lyche also points out. It
would be wrong, however, to call the species semi-marine. Such
a denomination would refer to an ecological status which the
species does not possess.
