Tipula (s.str.) (Diptera, Tipulidae). Norw. J. Entomol. 53, 1-4.
The Common cranefl y, Tipula (s.str.) oleracea Linnaeus, 1758, is recorded for the fi rst time from
Norway. A female specimen was collected at RY, Finnøy, Sevheim on 8 June 2005. A key to the
Norwegian Tipula (s.str.) is given. The potential spreading and pest status of T. oleracea is commented
upon.

(Coleoptera, Chrysomelidae) in the alpine zone at Finse, Norway. Norw. J. Entomol. 53, 5-9.
In the low alpine zone at Finse, Norway, Gonioctena pallida overwinters as adult in soil and litter
underneath shrubs of Salix spp. Larvae are present on Salix during the summer, and pupate in the litter
in the autumn. Due to a thick cover of snow, winter temperatures at the overwintering sites rarely
drops more than 1 or 2 °C below zero. In the laboratory, adult beetles survived 314 days at 2 °C, and
another 420 days at this temperature following a short period of feeding. The adults also survived
more than 8 months at –3 °C and more than six months at –6 °C. In contrast, all pupae died after two
months at 0 °C. Mean supercooling points of adult beetles stored at 0 °C remained close to –10 °C
during the winter. It is concluded that G. pallida is suffi ciently cold hardy to survive alpine winter
conditions in the adult stage. Apparently, the species has a one-year life cycle.

- Solevåg, P. K. 2006. Contribution to the knowledge of Coleoptera from Western Norway.
Norw. J. Entomol. 53, 11-19
New data are given for the distribution of 45 species of Coleoptera in Norway, 13 species being new to
Western Norway. Some ecological aspects are briefl y discussed. The beetle fauna of Western Norway
is poorly investigated, and the importance of faunistic surveys on all levels of beetle taxonomy seems
clear. Most of the species presented are common and widely distributed in Norway, other species have
a more restricted distribution, and some should even be reckoned as relicts from the postglacial warm
period. One species group shows a clear preference for oceanic climate: Quedius picipes (Mannerheim,
1830), Bolitobius inclinans (Gravenhorst, 1806) and Grynobius planus (Fabricius, 1787). Another
group has a more south-eastern distribution: Calosoma inquisitor (L, 1758), Badister lacertosus
(Sturm, 1815), Falagrioma thoracica (Stephens, 1832), Rhizophagus cribratus Gyllenhal, 1827,
Xyletinus ater (Creutzer, 1796) and Cerylon fagi Brisout de Barneville, 1867. Also hollow oaks in
the area revealed interesting species: Dienerella elongata (Curtis, 1830), Hapalaraea melanocephala
(Fabricius, 1787) and Batrisodes venustus (Reichenbach, 1816).
Key words: Coleoptera, Western Norway.

rediscovered in Norway. Norw. J. Entomol. 53, 21-22.
The stratiomyid fl y Clitellaria ephippium (Fabricius, 1775) is recorded from Norway for the fi rst time
since 1844. A single male was captured at Skoklefall in Nesodden municipality (AK) in 2005. The
species is previously recorded once in Norway, from AK Oslo: Fjeldstuen.

millipedes (Diplopoda) in North Norway. Norw. J. Entomol. 53, 23-38.
Based on 486 specimens collected over the last 70 years, the Chilopoda and Diplopoda in North
Norway were found to consist of four genera and eight species in the former, and seven genera each
of one species in the latter. All but two species, Pachyiulus varius (S European) and Oxidus gracilis
(anthropochorous), could be regarded as native. Four species (Lithobius melanops, L. tenebrosus,
Strigamia maritima and Nemasoma varicorne) were new to the area. From S to N, Nordland hosted
12 species, Troms 6 and Finnmark 5. Among the Chilopoda, numbers were 7, 5 and 5; in Diplopoda,
5, 1 and 0, respectively. Seven species were viewed as being common: Lithobius forfi catus, L.
erythrocephalus, Proteroiulus fuscus and Polydesmus denticulatus in Nordland, Lamyctes emarginatus
and Geophilus proximus in Nordland and Troms, and Lithobius curtipes in Finnmark. These are the
world‘s northernmost fi nds (65o04‘N-70o52‘N), except for curtipes, which also occurs in N Russia.
In Nordland, Polyxenus lagurus and Cylindroiulus latestriatus may be more common than this study
shows. Almost half the material was collected by schoolchildren in one year (2005). The children
proved to be useful collectors.

- Laugsand, A. E. 2006. Uleiota planata (L. 1761) (Coleoptera, Silvanidae) new to Norway. Norw. J.
Entomol. 53, 39-41.
Uleiota planata (L. 1761) (Coleoptera, Silvanidae) is here reported new to Norway. The records and
the locality are described. In Sweden the beetle probably became extinct and all the records after
1930 are connected to import of timber. The species might have been displaced through competition
from the close relative Dendrophagus crenatus (Paykull, 1799). Observations on the locality also
exclude the possibility of direct import of the specimens on timber, but one possibility is a secondary
settlement in the natural habitat after import on foreign timber. However, it is possible that U. planata
has been present continuously in fragments of virgin forest. The locality deserves further attention.

(Herbst, 1784) (Col., Melyridae) new to Norway. Norw. J. Entomol. 53, 51-53.
One specimen of Gonodera luperus (Herbst, 1783) (Family Tenebrionidae) was collected in a
window-trap at Kolsås, Bærum (EIS 28) in Akershus (AK). Several specimens of Anthocomus rufus
(Herbst, 1784) (Family Melyridae) have been found at four different localities in south-eastern
Norway during 2003 to 2005. These are the fi rst records of the two species in Norway.

Nematocera). Norw. J. Entomol. 53, 57-69.
Our knowledge about the Norwegian fauna of fungus gnats has improved considerably during the
last 15 years. With the present addition of 61 new species, 473 species belonging to the family
Mycetophilidae have been recorded from Norway. A complete check list for Norway is presented
together with detailed information for the new species. To enable comparison with previous lists from
Europe, references to literature for most species recorded or published after 1940 are added.

- Hågvar, S. & Aakra, K. 2006. Spiders active on snow in Southern Norway. Norw. J. Entomol. 53,
71-82.
In Norway, insects and springtails which are active on snow have been fairly well studied, but not
the spider fauna. A sample of 439 spiders collected on snow during many years and from several
localities in South Norway, contained 46 species, including 12 which were only identifi ed to genus
level. Spiders occurred on snow during all winter months, mainly at temperatures around or above
0 oC, but even down to –7 oC. Most species belonged to Linyphiidae. Comparisons with Finnish
pitfall-trapping below snow and a Norwegian study on the spider fauna on spruce branches during
winter show that nearly all species colonise the snow surface from the subnivean air space, probably
climbing up along stems and bushes penetrating the snow. In late winter, the spider fauna on snow is
dominated by Bolepthyphantes index, which constructs nets in small depressions in the snow surface,
for instance footprints of animals, and catches winter active springtails. During very warm days in
April, subadults of Philodromus sp. can start wind dispersal by sending out “fl ying threads” from
trees and may land in large numbers on snow. From there they probably seek snow-free patches. As
a group, spiders evidently contain many cold-adapted species, and Finnish studies have showed that
almost any species may be encountered on snow. Long-term pitfall trapping near Bergen showed
that some spider species had their main activity during winter, indicating winter reproduction. For
most spiders, their occurrence on snow in mild weather may simply be a continuation of their normal
subnivean activity. There should be a large evolutionary potential for more spider species to adapt to
use the food resource represented by winter active insects and springtails on snow.

- Greve, L. 2006. Lauxania minor (Martinek, 1974) (Diptera, Lauxaniidae) in Norway, and
Sapromyza obsoleta Fallén, 1820 (Diptera, Lauxaniidae) deleted from the Norwegian fauna.
Norw. J. Entomol. 53, 83-84.
Lauxania minor Martinek, 1974 is recorded as a new species to Norway from Bjørkås, Asker
Akershus (AK). Material previously published as Sapromyza obsoleta Fallén, 1820, has been
examined and proved to be misidentifi ed. S. obsoleta is therefore deleted from the Norwegian
fauna.

A checklist of the Nordic pseudoscorpions, including Norway, Denmark, Sweden, Finland, The Faroe
Islands and Iceland is presented. A total of 25 Nordic species are currently known, of which 16 are
from Norway, 19 from Denmark, 20 from Sweden, 17 from Finland, 1 from The Faroe Islands and 2
from Iceland.

1835) (Homoptera, Psyllidae) in Norway. Norw. J. Entomol. 53, 89–91.
Approximately 50 specimens of Cacopsylla visci were reared from a branch of mistletoe (Viscum
album) collected on the small Oslofjord island of Mølen at Hurum, E Buskerud (BØ); July 1990.
Attacks were also observed in July 1999, and both adults and nymphs (IV-V) were observed in early
May 2000, which indicates that the species may hibernate in these stages. This is the fi rst Fennoscandian
records of the species and represents most probably a new northern limit for the species.
