Abstract

Background

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).

New information

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

Introduction

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 (Ivanov 1966).

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) (Stoyanov 1966).

Information about findings of longhorn beetles of Rila is available in a number of literature sources (Heyrovský 1931, Kantardjiewa-Minkova 1932, Kantardjiewa-Minkova 1934, Minkova 1957, Minkova 1961, Angelov 1967, Angelov 1995, Ganev 1984, Ganev 1985, Ganev 1986, Doychev and Georgiev 2004, Migliaccio et al. 2007, Rapuzzi and Georgiev 2007 etc.). However, there is no check-list of cerambycid fauna of the mountain.

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.

Materials and methods

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 were studied by literature data, original records and unpublished materials in entomological collections.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 Sama 2002, Sama 2013, Téocchi 2003, Biscaccianti 2007, Lobl and Smetana 2010, Özdikmen 2011, Miroshnikov 2016 and Danilevsky 2021 are followed, without indication of tribes and subgenera. Some taxa reported from Rila Mt., but most likely misidentified, are not included in the list: Agapanthia lais Reiche & Saulcy, 1858 (Bringmann 1995) and Phytoecia affinis nigropubescens G. Müller, 1948 (reported as Phytoecia nigripes nigropubescens in Bringmann (1998)).

The zoogeographical characterisation of longhorn beetles was made on the basis of recent taxa distribution (Danilevsky 2021). According to Georgiev and Hubenov (2006) and Sakalian and Langourov (2007) conceptions, the established taxa are arranged in 18 chorotypes (areographic categories).

The new cerambycid records are deposited in entomological collection of Georgi Georgiev (mentioned with the abbreviation [GG]).

Three taxa were previously reported under synonymous names: before revision of Danilevsky (2021), Stenurella bifasciata intermedia was reported as Stenurella bifasciata; recently described Purpuricenus kaehleri rossicus is distributed in Central and partly South Europe, including Bulgaria (Danilevsky 2021). Danilevsky (2019) mentioned that, in his collection, all materials of Leiopus nebulosus from Russia and adjacent countries, including Bulgaria, belong to recently described Leiopus linnei (Wallin et al. 2009).

The established cerambycid taxa belong to 18 areographical categories separated in seven complexes (Table 2).

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. 1).

Discussion

The number of cerambycid taxa found in Rila Mt. (126 species and subspecies) is closest to that of Vitosha Mt. (122 taxa) (Topalov 2018). It is comparable to the number of cerambicides in other studied mountains in Bulgaria: Western Rhodopes (161 taxa) (Georgiev et al. 2006), West Balkan Range (107 taxa) (Georgiev 2011, Gradinarov and Petrova 2019) and Strandzha (154 taxa) (Georgiev et al. 2018).

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 (Topalov 2018). Vitosha with its elevation, oreographic patterns and vegetation is comparable to Rila Mt. Concerning the other two studied Mountains in Bulgaria - Strandzha (Georgiev et al. 2018) and Belasitsa (Georgiev et al. 2019), domination of European cerambycids was also established (33.1% and 38.2%, respectively), but the Mediterranean taxa take a greater share in both mountains (27.3% and 19.1%, respectively). In addition, European-Iranoturanian taxa are mostly represented in Strandzha Mt. (13.6%) compared to other mountains (7.2-11.1%). The level of Balkan and Bulgarian endemics is higher in Belasitsa Mt. – nine taxa (8.2%), followed by Rila Mt. – five taxa (4.0%), Strandzha Mt. – five taxa (3.3%) and Vitosha Mt. – two taxa (1.7%). Evidently, the conditions in Belasitsa Mt. and, especially, the distribution of relict forests of Castanea sativa, are the most suitable for occurrence of endemics there.

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.
