Xylotrechus (Rusticoclytus) pantherinus

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.Published as part of Gradinarov, Denis & Sivilov, Ognyan, 2020, First records of Xylotrechus pantherinus (Savenius, 1825) and X. stebbingi Gahan, 1906 (Cerambycidae: Cerambycinae) in Bulgaria, pp. 1-4 in ZooNotes 161 on page 2, DOI: 10.5281/zenodo.830144
