Taxonomic review of the genus Euboeus s. str. Boieldieu, 1865 (= Probaticus s. str. Seidlitz, 1896, syn. n.) (Coleoptera, Tenebrionidae)

WOS: 000416784000006PubMed ID: 29245459The taxonomic history and position of the genera Euboeus and Probaticus within the tribe Helopini are discussed. A new synonymy, based on morphological characters is established: Euboeus Boieldieu, 1865 = Probaticus (s. str.) Seidlitz, 1896, syn. n. As a result, 67 new combinations (from Probaticus to Euboeus) are estabished for all species formerly placed in Probaticus. A review of Euboeus s. str. with four species (Balkanian-Anatolian E. mimonti Boieldieu, 1865 and E. tentyrioides (Kaster, 1851), Greek E. mori (Brull, 1832), and Anatolian E. parvostriatus sp. n.) is given. Three new synonyms are established for Euboeus tentyrioides (= Micispa bysantica Motschulsky, 1858, syn. n.; = Micispa pyraei Motschulsky, 1858, syn. nov.; = Micispa graeca Motschulsky, 1858, syn. n.). The forgotten name Helops (Euboeus) parvicollis Baudi di Selve, 1876, nomen oblitum (junior synonym of E. tentyrioides) is discussed. A lectotype is designated for Helops tentyrioides. A key to the four species within the revised Euboeus sensu stricto, along with distributions and images, is provided.Russian Foundation for Basic ResearchRussian Foundation for Basic Research (RFBR) [15-04-02971-a]The authors are much obliged to Dr. Denis Kasatkin (Rostov Branch of All-Russian Center for Plant Quarantine, Rostov-on-Don) for the preparation of photographs of E. mori, E. parvostriatus sp. n. and the lectotype of E. tentyrioides, to Aaron Smith (Northern Arizona University, USA), OttO Merkl and anonymous reviewer for the valuable comments and linguistic corrections.

Osmoderma eremita (Coleoptera, Scarabaeidae, Cetoniinae) in Europe

Research, monitoring and development of preservation strategies for threatened species are often limited by national borders even though a global perspective would be more appropriate. In this study, we collected data on the occurrence of a threatened beetle, Osmoderma eremita, associated with tree hollows in 2,142 localities from 33 countries in Europe where it is or has been present. The larvae develop in tree hollows and very few observations of larvae have been observed in dead logs on the ground. As long as there is a suitable tree hollow, it appears that O. eremita may use any tree species. Oaks (Quercus spp.) are the trees mainly used by O. eremita, followed by lime (Tilia spp.), willow (Salix spp.), beech (Fagus sylvatica) and fruit trees (Prunus spp., Pyrus spp., Malus domestica). O. eremita is still found in some remnants of natural forest, but is mainly observed on land that has long been used by man, such as pasture woodlands, hunting parks, avenues, city parks and trees around agricultural fields and along streams. The occurrence of O. eremita seems to have decreased in all European countries. Relatively high densities of O. eremita localities occur in Central Europe (northern Italy, Austria, Czechia, southern Poland and eastern Germany), some parts of Northern Europe (south-eastern Sweden, Latvia) and France. In some regions in north-western Europe, the species is extinct or may occur at some single sites (Norway, Danish mainland, The Netherlands, Belgium, north-eastern France). There are few data from south-eastern Europe. Many local extinctions of O. eremita are to be expected in the near future, especially in regions with recent habitat loss and fragmentation. O. eremita is useful as an indicator and umbrella species for the preservation of the entire invertebrate community associated with hollow trees in Europe. A preservation plan for O. eremita should include three aspects that are of general importance in nature conservation in Europe today: (1) preservation of remnants of natural forests with old, broad-leaved trees, (2) preservation and restoration of habitats related to traditional agricultural landscapes and (3) preservation of remaining ‘islands’ of nature in urban areas
