Sammanfattning

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.
