|
The longhorn beetles fauna of Pirin Mountains, Bulgaria, was studied, based on literature data and original material. As a result, 100 taxa from five subfamilies are listed for the area, as follows: Prioninae (7 taxa), Lepturinae (31 taxa), Spondylidinae (9 taxa), Cerambycinae (28 taxa) and Lamiinae (25 taxa).
This study presents two new records for Pirin Mts. (Oxymirus cursor and Tetropium fuscum fuscum) and new localities or additional information for 13 cerambycid taxa (species and subspecies). The 100 longhorn beetle taxa belong to 17 zoogeographical categories and eight complexes. The European complex occupies a dominant position (34%), followed by those from Palaearctic (17%), Eurosiberian (15%), Mediterranean (15%), European-Iranoturanian (9%), Balkan endemic (5%) and Holarctic (4%) complexes.
Pirin Mountains, cerambycids, faunistics, chorology
Pirin is the second highest mountain in Bulgaria. The highest peak of the mountain, Vihren (2914 m), occupies the third position on the Balkan Peninsula after Musala (2925 m) in Rila (Bulgaria) and Mytikas (2918 m) in Olympus (Greece). The average altitude of Pirin Mts. is 1033 m a.s.l. and the total area is 2585 km2.
The vegetation of Pirin Mts. is vertically divided into three altitude belts: forest, subalpine and alpine. The lower part of the forest belt is predominantly made up of broad-leaved species stands (Carpinus betulus, Quercus petraea, Fagus sylvatica, Populus tremula etc.) and the upper part is mainly occupied by conifers (Pinus nigra, P. sylvestris, P. peuce, P. heldreichii, P. mugo, Abies alba and Picea abies) (
The Bulgarian cerambycid fauna (Coleoptera, Cerambycidae) is relatively well studied. Fragmentary data about findings of longhorn beetles in different mountains of the country, including Pirin, are available in many publications (
The aim of this study is to summarise the published data about longhorn beetles in the Pirin Mts., report new records and provide a chorological analysis of the cerambycid fauna of this mountain range.
The longhorn beetles of Pirin Mts. were studied using literature data, our original records and unpublished materials from the entomological collection of the National Museum of Natural History, Sofia. The original material was collected on flowers, host plants and using an interception trap in a tree crown of Pinus heldreichii.
In this study, we followed the classification and nomenclature of longhorn beetles proposed by
The zoogeographical characterisation of longhorn beetles was made on the basis of chorotypes (
This paper provides a map with all known localities of the longhorn beetles recorded from Pirin Mts. It includes new localities from the current study and those already published. The records without a specific location, such as "Pirin Mt.", were not marked on the map.
Thecerambycid specimens collected in this study were deposited in the private entomological collection of Georgi Georgiev (mentioned with the abbreviation [GG]).

According to the present study, 15 species are reported for Pirin Mountains. Of these, two species Oxymirus cursor and Tetropium fuscum fuscum are new records and new localities or new specimens are given for 13 species. Summarising our data with the published one, 100 cerambycid taxa from 32 localities are recorded in Pirin Mts. (Fig.

The recorded cerambycid taxa belong to five subfamilies: Prioninae (7 taxa), Lepturinae (31 taxa), Spondylidinae (9 taxa), Cerambycinae (28 taxa) and Lamiinae (25 taxa) (Table

The taxa from the European complex are dominant in Pirin Mts. (34%) followed by those from Palaearctic (17%), Eurosiberian (15%) and Mediterranean (15%) complexes (Fig.
The number of cerambycid taxa found in Pirin Mts. (100 species and subspecies) is closest to the West Balkan Range (107 taxa) (
In this study, taxa of the European complex occupy a dominant position (34%). They are connected with deciduous forests, which cover the largest parts of the lower territories of Pirin Mts. The second place is taken by the species and subspecies belonging to the Palaearctic complex (17%). These more eurybiont taxa are normally better represented in the high mountains, because of the harsh climatic conditions. Eurosiberian and Mediterranean complexes with equal value (15%) occupy the third place. This pattern differentiates Pirin from the rest of the studied high mountains - Vitosha (
The high territories mostly covered by coniferous trees and shrubs are favourable for distribution of the Eurosiberian taxa (fourth place). The refugial character of the region is underlined by the presence of five (5.0%) Balkan endemic cerambycids.
Concerning the other two studied mountains in Bulgaria - Strandzha (
In future investigations, the cerambycid fauna of Pirin Mt. will undoubtedly be enriched with species trophically associated with coniferous trees in the the mountains of Bulgaria, such as: Lepturobosca virens (Linnaeus, 1758), Acmaeops septentrionis Thomson, 1866, Acmaeops pratensis (Laicharting, 1784), Evodinellus clathratus (Fabricius, 1793), Molorchus marmottani marmottani Brisout de Barneville, 1863, Pachyta lamed (Linnaeus, 1758), Paracorymbia maculicornis (De Geer, 1775), Pidonia lurida (Fabricius, 1793), Semanotus undatus (Linnaeus, 1758), Acanthocinus griseus (Fabricius, 1793), Acanthocinus reticulatus Razoumowsky, 1789 and Monochamus sartor (Fabricius, 1787) (
It is expected that longhorn beetles with Eurosiberian, Palearctic and European distribution associated with coniferous, broadleaved and grass vegetation in other mountains in south-western Bulgaria – Rila, Western Rhodopes and Belasitsa (
Due to the specific location of Pirin in south-eastern Europe and the penetration of Mediterranean influence along the valleys of the Struma and Mesta Rivers, it is very likely that species with European-Iranian and Mediterranean distribution reported for Rila and Belasitsa (
Regarding the endemic complex, in future research, it is likely that other species reported for neighbouring Rila and Belasitsa Mts. may also be found: Agapanthia schurmanni Sama, 1979, Dorcadion aethiops strumense Danilevsky, 2014, Dorcadion axillare Küster, 1847, Dorcadion sturmii Frivaldszky von Frivald, 1837 and Phytoecia geniculata orientalis Kraatz, 1871 (
Only three cerambycids were recorded in trophic associations with tree and shrub species in the Pirin Mts.: Arhopalus rusticus rusticus and Pogonocherus fasciculatus fasciculatus were reared from stems and branches of Pinus nigra (
In conclusion, finding of 100 taxa (approximately 35% of longhorn beetles in Bulgaria) indicates that this taxonomic group is not yet well-studied and about 70–80 taxa are expected to be recorded in future investigations in the Pirin Mts.
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).
