Solevåg: Coleoptera from Western Norway
bisected distribution in Norway; most common
in the southeastern areas, scattered from STI
and northwards (Vik 1991). Also found in HOY
(Skartveit et.al 2004), occurring only in the most
productive parts of the deciduous forests. More
eurytopic in the present study, found both in
Calluna pine forest and elm/lime forest, more in
co ordinance with (Koch 1989b).
Cerylonidae
Cerylon fagi Brisout de Barneville, 1867
SFI Balestrand: Målsnes (EIS 50) 15 May-7
August 2001, two specimens, Tjugum (EIS 50) 15
May-7 August 2001, one specimen. First records
from western Norway, previously recorded from
areas around the Oslo fjord and along the southern
coast from AAY to RY (Vik 1991). Under bark
(Koch 1989b), prefers beech, oak, poplar and elm,
according to Hansen (1951).
Latriidae
Dienerella elongata (Curtis, 1830)
SFI Balestrand: Målsnes (EIS 50) 7.August-3
November 2001, four specimens; Leikanger:
Hella (EIS 50) 4 April-3 November 2001, nine
specimens; Luster: Luster (EIS 60) 15 May-6
August 2001, five specimens. The first record
from western Norway, previously recorded from
Ø, AK, VE, AAY and STY, but due to the wider
distribution in Sweden (Lundberg 1995), and
the small size of the beetle, it may have a wider
distribution in Norway. Found in rotten and
decaying vegetation of different kind (Hansen
1951), eurytopic and synanthropic (Koch 1989b);
also found in connection with tree fungi (Økland
& Hågvar 1994) and in pine forest (Hansen and
Ligaard 1992).
Ciidae
Orthocis vestitus (Mellié, 1848)
SFI Årdal: Seimsdal (EIS 51) 14 May-6 August
2001, two specimens. First records from western
Norway, previously known from AK and VE
(Vik 1991). Found in deciduous and mixed forests
(Koch 1989b), foraging on different kinds of fungi
(Hansen 1951).
16
Chrysomelidae
Acalles ptinoides (Marsham, 1802)
SFY Høyanger: Torvund (EIS 49) 16 May-7
August 2001, one specimen in an open Calluna
type pine stand. Recorded along the coast from
VE to SFY (Figure 4) (Vik 1991).
More species new to SFI and SFY.
Table 1 gives a list of the other species recorded in
the present study new for this part of Norway.
DISCUSSION
Most ecological or faunistic studies on beetles in
Norway have been carried out in southeastern,
middle and northern parts of Norway (Andersen
et al. 1992, Andersen & Olberg 2003, Birkemoe
1993, Fossli & Andersen 1998, Hansen & Ligaard
1992, Hågvar 1999, Thingstad 1987, Ødegaard &
Ligaard 2000, Økland & Hågvar 1994), although
some literature on the species` distribution and
ecology in western Norway is available (Andersen
& Fjellberg 1975, Hanssen & Olsvik 1982, Key
1981, Kålås 1985, Pedersen 1986, Refseth 1979,
1987, Thunes 1993). Despite these studies the
beetle fauna of western Norway is poorly known
(Refseth 1987, Andersen et al. 1992), particularly
among the staphylinids.
The majority of the species presented in the
present paper should be reckoned as common and
widely distributed in southern Norway, although
previously not known from Western Norway;
most likely due to little collecting here. However,
the distribution of some species is discussed in the
present paper.
Several species have a coastal distribution in the
Nordic countries, indicating their preferences for
oceanic climate. This applies to the staphylinids
Quedius picipes, Bolitobius inclinans and
the anobiidae Grynobius planus. Especially
Grynobius planus is restricted to the western
coast of both Norway and Sweden (Figure 3) (Vik
1991, Lundberg 1995), depending on decaying
wood in the warm boreo-nemoral deciduous forest
(Hansen & Ligaard 1992). Acalles ptinoides has
