[email protected] Abstract We reviewed the distribution of the two Asian species of the genus Sceliphron Klug, introduced into Europe in the late 1970s to early 1980s: S. (Hensenia) curvatum (Smith) and S. (Hensenia) deforme (Smith). Both species are routinely considered as invasive in Europe, but the status and effects of their (eventual) invasiveness are yet to be documented and evaluated. We had a focus on two areas, the Balkan Peninsula and European Russia, based principally on the study of specimens collected over the last 15 years, but we also reviewed the extensive published evidence (including some very important internet-based records), and for S. curvatum we provided a concise overview of the entire European range.
