The complex of longhorn beetles in Rila Mt. in Bulgaria was studied by literature data and original biological materials. As a result, 126 taxa from six subfamilies were established, as follows: Prioninae (four taxa), Lepturinae (43 taxa), Necydalinae (two taxa), Spondylidinae (seven taxa), Cerambycinae (31 taxa) and Lamiinae (39 taxa).
In this study, two new records for Rila Mt. (Stenurella nigra nigra and Xylosteus spinolae) and new localities or additional information for 24 cerambycid taxa were reported. The longhorn beetles belong to 18 zoogeographical categories and seven complexes. The European complex occupies a dominant position (37.3%), followed by the Palaearctic (23.8%), Eurosiberian (13.5%), Mediterranean (11.1%), European-Iranoturanian (7.1%), Balkan endemic (4.0%) and Holarctic (3.2%) complexes.
Cerambycidae, Rila Mt., areography, Bulgaria
Rila is the highest and one of the largest mountains in Bulgaria. The average altitude is 1487 m a.s.l. and the total area - 2629 km2. The highest peak of the mountain, Musala (2925 m a.s.l.), is the highest on the Balkan Peninsula and in Eastern Europe (
In Rila Mt., there is a large number of tree and shrub species clearly distributed in vegetation belts. The deciduous belt is formed mainly by hornbeam (Carpinus betulus L.), sessile oak (Quercus petraea (Matt.) Liebl.), common beech (Fagus sylvatica L.), aspen (Populus tremula L.) and birch (Betula pendula Roth) and coniferous one - by silver fir (Abies alba Mill.), Norway spruce (Picea abies (L.) Karst.), Scots pine (Pinus sylvestris L.), Balkan pine (Pinus peuce Griseb.) and dwarf mountain pine (Pinus mugo Turra) (
Information about findings of longhorn beetles of Rila is available in a number of literature sources (
The aim of this study is to sumarise data in entomological literature about longhorn beetles in Rila Mt., to report new records of longhorn beetles and to make zoogeographical analysis of cerambycid fauna in the mountain.
The longhorn beetles of Rila Mt. were studied by literature data, original records and unpublished materials in entomological collections. The original material was collected on flowers and host plants.
In this study, classification and nomenclature of the longhorn beetles suggested by
The zoogeographical characterisation of longhorn beetles was made on the basis of recent taxa distribution (
The new cerambycid records are deposited in entomological collection of Georgi Georgiev (mentioned with the abbreviation [GG]).

In this study, two new taxa (Stenurella nigra nigra and Xylosteus spinolae) were established for Rila Mt. New localities or additional information for 24 cerambycid taxa were also reported.
The total number of cerambycid taxa in Rila Mt. is 126 from six subfamilies: Prioninae (four taxa), Lepturinae (43 taxa), Necydalinae (two taxa), Spondylidinae (seven taxa), Cerambycinae (31 taxa) and Lamiinae (39 taxa) (Table

The taxa from the European complex are dominant in Rila Mt. (37.3%), followed by those from Palaearctic (23.8%), Eurosiberian (13.5%) and Mediterranean (11.1%) complexes (Fig.
The number of cerambycid taxa found in Rila Mt. (126 species and subspecies) is closest to that of Vitosha Mt. (122 taxa) (
In this study, the taxa of the European complex occupy a dominant position. They are connected with deciduous forests, which cover most of the mountainous territory of Rila. The second place is taken by the species and subspecies belonging to Palaearctic complex. These more euribiont taxa with broad areas of distribution normally are better presented in the high mountains, because of the harsh climatic conditions there. The third and fourth positions take taxa belonging to Eurosiberian and Mediterranean complexes. The high territories, mostly covered by coniferous trees and shrubs, are favourable for distribution of the Eurosiberian taxa. In the lower parts and along the rivers, conditions in Rila Mt. allow penetration of Mediterranean taxa. The refugial character of the region is underlined by the presence of five (4%) Balkan endemic cerambycids.
Similar aerographic characteristics of cerambycid fauna were established in Vitosha Mt. where European taxa (36.4%) take first place, followed by Palaearctic (20.6%), Eurosiberian (14.0%) and Mediterranean (12.4%) taxa (
In conclusion, it should be noted that the finding of 126 taxa (approximately 45% of longhorn beetles in Bulgaria) indicates that this taxonomic group is not yet well-studied and about 50 species and subspecies are expected to be found in future investigations in Rila Mt.
This study was supported by the project ‘Structural and functional characteristics and perspectives for the use of endemic relict coniferous communities in the changing climate in Bulgaria, funded by the National Science Fund of Bulgaria (Grant no. KP-06-NP36/13/17.12.2019).
