Abstract
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 recent economic downturn severely affected the US forest sector from a macro-economic perspective but little is known about changes in firm-level performance. In this study we investigate the changes in financial, social and environmental performance of forest sector firms during a period approximately corresponding to the downturn. We also assess industry dynamism and industry’s view about social and environmental responsibility as a competitive tool. We conducted a national survey of wood, furniture and paper companies. Approximately sixty percent of our respondents reported a decline in financial performance during the downturn. With respect to social and environmental performance, customer oriented actions show mixed trends, employee matters remained somewhat unaltered, community engagement significantly decreased, and engagement in environmental activities significantly increased. Respondents view their operating business environment as highly dynamic and difficult and they do not view engagement in social and environmental responsibility activities leading to either financial or non-financial benefits.
