Silva Balcanica, 19(3)/2018 A CHECK LIST AND AREOGRAPHY OF LONGHORN BEETLES (COLEOPTERA: CERAMBYCIDAE) IN VITOSHA MOUNTAIN Pavel Topalov Forest Research Institute – Sofia, Bulgarian Academy of Sciences Abstract The analysis of literature data and studies of original biological materials showed that the complex of longhorn beetles in Vitosha Mt. includes 121 taxa from six subfamilies: Prioninae (2 species), Lepturinae (37 species and subspecies), Necydalinae (1 species), Spondylidinae (7 species and subspecies), Cerambycinae (35 species and subspecies) and Lamiinae (39 species and subspecies). Three species and one subspecies were established as new for Vitosha Mt.: Aegosoma scabricorne, Pedostrangalia (Pedostrangalia) revestita, Stictoleptura (Melanoleptura) scutellata scutellata and Hylotrupes bajulus. The established taxa belong to 20 zoogeographical categories and 7 complexes. The European complex occupies a dominant position – 44 taxa (36.4%), followed by the Palaearctic complex – 25 taxa (20.6%). The Mediterranean and Eurosiberian taxa are almost equally presented in the total complex – 15 taxa (12.4%) and 17 taxa (14.0%), respectively. However, the cerambycid endemics in Vitosha Mt. (two taxa, 1.7%) have a smaller share compared to endemics for the country (6.8%). Key words: Cerambycidae, areography, Vitosha Mt., Bulgaria INTRODUCTION The cerambycid fauna (Coleoptera: Cerambycidae) of Vitosha is relatively well studied due to the disposition of the mountain near to Sofia, and the interest of collectors to this taxonomic group. It should be noted, however, that despite the existence of numerous publications and two targeted studies (Migliaccio et al., 2004; Doychev et al., 2009), there is still a lack of enough knowledge about the species composition, distribution and host plants of the longhorn beetles in the mountain. The aim of this study is to report new data about distribution of cerambycids in Vitosha, as well as to represent new records and to make areographic analysis of cerambycid fauna of the Mountain. MATERIAL AND METODS The present work is based on literature data and original research results. 25 The original studies were conducted during the period 2015-2017 by the following entomological methods: hand collection of cerambycids on flowers and host plants; collection of adult insects on grass, bushes and low parts of tree crowns with entomological bag; identification of larvae and adults found in tissues and organs of tree and shrub vegetation; rearing of adults in laboratory conditions from infested stems and branches of host plants. The new taxa for Vitosha Mt. are marked with an asterisk (*). The adults were identified by the keys of Plavilstshikov (1936, 1940, 1958) and Bense (1995), and the larvae – by the keys of Švácha, Danilevsky (1986, 1987, 1988). The longhorn beetles are listed in systematic order, by the system of Danilevsky (2018), without indicated tribes. The data about recent cerambycids taxa distribution is based on Danilevsky (2018). According to Georgiev & Hubenov (2006), Sakalian & Langourov (2007) and Georgiev et al. (2018) conceptions, the established taxa are arranged in 20 chorotypes (areographic categories). RESULTS The total number of cerambycid taxa in Vitosha Mt. is 121 from five subfamilies: Prioninae (2 species), Lepturinae (37 species and subspecies), Necydalinae (1 species), Spondylidinae (7 species and subspecies), Cerambycinae (35 species and subspecies) and Lamiinae (39 species and subspecies).
