Gonodera luperus (Herbst, 1783) (Col., Tenebrionidae)<br />

and Anthocomus rufus (Herbst, 1784) (Col., Melyridae)<br />

new to Norway<br />

Stefan Olberg<br />

THE SPECIES<br />

Gonodera luperus (Herbst, 1783)<br />

One specimen <strong>of</strong> Gonodera luperus (Figure 1)<br />

(family Tenebrionidae) was caught in a windowtrap<br />

at AK Bærum: Kolsås (EIS 28) 15 June – 7<br />

July 2005, leg. and coll. S. Olberg. The fairly large<br />

(7-9 mm) darkling beetle G. luperus, belonging to<br />

the subfamily Alleculinae, is previously known<br />

from Sweden, Denmark and Estonia in Northern<br />

Europe (Silfverberg 2004). In Sweden it is recorded<br />

in several <strong>of</strong> the southern districts (Sk, Bl, Sm, Öl,<br />

Go, Ög, Sö, Up, Vs) (Lundberg 1995). G. luperus<br />

is widespread but not common in both Sweden<br />

and Denmark (Hansen 1938). It is therefore not<br />

surprising that the species also appears in southeastern<br />

parts <strong>of</strong> Norway. Despite the relatively<br />

large size <strong>of</strong> G. luperus, it has so far not been<br />

detected in Norway and must be regarded as rare.<br />

The larva develops in rotten wood <strong>of</strong> various<br />

deciduous trees while imago visits flowers. It is<br />

unlikely that this is a newly invaded species, but<br />

its rarity and probable restricted distribution in<br />

Norway, most likely explain why this species has<br />

been undetected in the <strong>Norwegian</strong> fauna.<br />

(Herbst, 1784) (Col., Melyridae) new to Norway. Norw. J. Entomol. 53, 51-53.<br />

One specimen <strong>of</strong> Gonodera luperus (Herbst, 1783) (Family Tenebrionidae) was collected in a<br />

window-trap at Kolsås, Bærum (EIS 28) in Akershus (AK). Several specimens <strong>of</strong> Anthocomus rufus<br />

(Herbst, 1784) (Family Melyridae) have been found at four different localities in south-eastern<br />

Norway during 2003 to 2005. These are the first records <strong>of</strong> the two species in Norway.<br />

Key words: Gonodera luperus, Anthocomus rufus, Tenebrionidae, Melyridae, Norway<br />

Anthocomus rufus (Herbst, 1784)<br />

The first specimens <strong>of</strong> Anthocomus rufus (Figure<br />

2) (family Melyridae) were found in Norway at<br />

AK Bærum: Oksenøya (EIS 28) Aug. 2003, leg.<br />

J. Pedersen, coll. NHM and S. Olberg. Three<br />

specimens were sweep-netted on Phragmites<br />

communis. Two additional specimens were sweepnetted<br />

at the same locality in Sept. 2005, leg. L.O.<br />

Olberg. Sweep-netted on a meadow. Ø Hvaler:<br />

and coll. S. Ligaard. TEY Skien: Børsesjø (EIS<br />

malaise-trap, leg. K.M. Olsen, coll. NHM and S.<br />

Olberg.<br />

A. rufus is a widespread species in southern parts <strong>of</strong><br />

Sweden (Lundberg 1995) and there are reports <strong>of</strong><br />

an expansion or at least an increase in the Swedish<br />

populations during the last couple <strong>of</strong> years. Such<br />

an expansion in our neighbouring country could<br />

have lead to an invasion in south-eastern Norway.<br />

An invasion or at least an expansion in Norway is<br />

supported by the fact that A. rufus was found at<br />

three localities situated far from each other within<br />
