1. Natura 2000 network (N2000) and national protected areas (NPAs) are recognised as the most important core ‘units’ for biological conservation in Europe.2. Species distribution models (SDMs) were developed to detect the potential distribution of the rare and threatened cerambycid beetle Rosalia alpina L. in Europe, and the amount of suitable habitat within the N2000 network [special areas of conservation (SACs) and special protection areas (SPAs)], NPAs (e.g. national parks, regional parks, state reserves, natural monuments and protected landscapes) and the overall European protected area network (EPAN) (N2000 + NPAs) was quantified.3. According to this analysis, the suitable habitat for R. alpina in Europe amounts to c. 754 171 km2 and stretches across substantially uninterrupted areas from Portugal to Romania (west to east) and from Greece to Germany (south to north). The overlay between the existing system of conservation areas in Europe (N2000 and NPAs) and the binary map for R. alpina showed that only c. 42% of potential habitat is protected. SACs and SPAs protect c. 25% and 21% of potential habitat, respectively. However, because the two site types often spatially overlap, when taken together the entire N2000 network protects c. 31% of potential habitat. Instead, NPAs offer a degree of protection of c. 29%. Overall, almost 60% of the area potentially suitable for the species is unprotected by the EPAN, an aspect that should be considered carefully when planning the conservation of this beetle at a large scale.4. These results may also help to focus field surveys in selected areas where greater chances of success are encountered to save resources and increase survey effectiveness.
A systematic study on <em>Purpuricenus interscapillatus</em> Plavilstshikov, 1937 and related species from southern European and Near East areas is here presented. Several changes in rank status and a new synonymy are proposed, and four new subspecies are described as below: <em>Purpuricenus interscapillatus</em> ssp. <em>barbarae</em> n. ssp. (NW Israel); <em>Purpuricenus interscapillatus</em> ssp. <em>hermonensis</em> n. ssp. (NE Israel); <em>Purpuricenus</em> <em>renyvonae</em> ssp. <em>neocaucasicus</em> n. ssp. (Turkey, Caucasus); <em>Purpuricenus</em> <em>globulicollis</em> ssp. <em>skypetarum</em> n. ssp. (Albania). The following nomenclatural changes are also introduced: <em>Purpuricenus interscapillatus</em> ssp. <em>nabataeus</em> Sama, 1999 stat. nov.; <em>Purpuricenus</em> <em>interscapillatus</em> ssp. cornifrons Pesarini & Sabbadini, 1992 stat. nov.; <em>Purpuricenus interscapillatus</em> ssp. <em>longevittatus</em> Pic, 1941 stat. nov.; <em>Purpuricenus apiceniger</em> Pic, 1914 stat. nov. After studying of the type specimen the following new synonymy is also proposed: <em>Purpuricenus kaehleri</em> ssp. <em>menetriesi</em> Motschulsky, 1845 = <em>Purpuricenus budensis</em> var. <em>caucasicus</em> Pic, 1902 syn. n.
