The male and female genitalia characters of the European species of Monochamus Dejean, 1821, are described and compared in detail for the first time. The sclerites inside the median phallomer (internal sac) of M. sutor (Linnaeus, 1758) and M. galloprovincialis (Olivier, 1795) differ from those of all other examined species, and appear to be the best characters to separate M. sutor from M. galloprovincialis. There are no differences between the male or female genitalia characters of M. sartor (Fabricius, 1787) and M. urussovi (Fischer von Waldheim, 1805). Thus, M. urussovi is regarded as a subspecies of M. sartor: M. sartor urussovi nov. stat. The present results also support that the previously considered subspecies M. galloprovincialis pistor (Germar, 1818) is a true junior synonym of M. galloprovincialis galloprovincialis. No sclerites occur inside the internal sac of M. saltuarius (Gebler, 1830). The internal sac of M. sartor sartor (Fabricius, 1787), M. sartor urussovi and M. impluviatus impluviatus (Motschulsky, 1859) are distinctly different from the other European species of Monochamus: there is an elongated tube (terminal segment) inside the internal sac containing two very small and weakly sclerotized plates in M. sartor sartor and M. sartor urussovi and a larger sclerite in M. impluviatus impluviatus. A key to the European species and subspecies of Monochamus, incorporating male genitalia characters, is provided.

The distribution of Leiopus nebulosus (Linnaeus, 1758) and L. linnei Wallin, Nylander & Kvamme, 2009, in Norway is discussed and depicted. Observations of host trees as well as information of substrate qualities and phenology are included.

Ikke alle artene som kan følge med fyringsved er vanlige. Av og til dukker det opp insektarter som bare forkommer lokalt i mindre områder av landet og som derfor må betraktes som sjeldne.

Originally, Trypophloeus dejevi (Stark, 1936) was described from Sakhalin Island in the Far East of Russia, and it remained undetected in Europe until 2009, when one Swedish specimen was found in the collection of the late Lars Huggert. This specimen was sampled in Northern Sweden in Torne Lappmark: Årosjokk, 67°52’ N/19°22’E, in 1968. In 2010, the species was found in five new localities in the same area. Here we present T. dejevi, recorded in 2012 as a new species to Norway and Finland. In Norway, galleries with beetles were found in Salix myrsinifolia Salisbury and in Finland Salix glauca L. was the observed host tree. Both are common willow species in Northern Fennoscandia. The distribution of the beetle within trunks of living Salix combined with a low population-density may be an explanation to why T. dejevi has been overlooked until now.
