First records of Xylotrechus pantherinus (Savenius, 1825) and X. stebbingi Gahan, 1906 (Cerambycidae: Cerambycinae) in Bulgaria Author Gradinarov, Denis Author Sivilov, Ognyan text ZooNotes 2020 2020-06-06 161 1 4 journal article 264459 10.5281/zenodo.8301445 ed9d954d-d3b5-4223-bf99-11568eaa03b0 1313-9916 8301445 Xylotrechus ( Rusticoclytus ) pantherinus (Savenius, 1825) ( Fig. 2 : A) Material examined: Bulgaria : Sofia , June 2015 , 1 ♂ (unknown collector) . X. pantherinus is a Eurosiberian species with boreomontane distribution in Europe ( Hellrigl 2012 ). The species is monophagous on Salix spp. (Salicaceae) (in the European part of its range - on S. caprea L.) ( Sama 2002 ). Almost throughout all its European range, the species is considered to be rare ( Laugsand et al. 2008 , Kierdorf-Traut 2009 , Serafim 2009 , Ilić & Ćurčić 2015 ). Only in this century the species was reported in France ( Brustel et al. 2002 ) and in Lithuania ( Tamutis et al. 2011 ). Тhe apparent rarity of X. pantherinus may be due to its fragmented distribution and peculiarities in its biology (e.g. Laugsand et al. 2008 , Hellrigl 2012 ). Considering that the species is known from Romania ( Serafim 2009 ) and Serbia ( Ilić & Ćurčić 2015 ), its presence in Bulgaria is not surprising. The species has probably been overlooked in previous studies. New findings of this species from the country are desirable.
