03F9CE75FFA3E951BBE9FF03B403FD6E.taxon	discussion	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.	en	Gradinarov, Denis, Sivilov, Ognyan (2020): First records of Xylotrechus pantherinus (Savenius, 1825) and X. stebbingi Gahan, 1906 (Cerambycidae: Cerambycinae) in Bulgaria.

03F9CE75FFA3E952BBE9F9F8B140FEF9.taxon	discussion	X. stebbingi originated from Central and South Asia and has recently been introduced in the Mediterranean region (Gahan 1906, Sama 2002). In Europe, by the end of the 20 th century the species was found in Italy, Switzerland, France and Greece (Sama 2002). In the present century X. stebbingi was reported in Slovenia, Croatia (Brelih et al. 2006), Spain (Recalde & San Martín 2015) and Albania (Kovács 2015). The known localities of the species in Northern Greece (Sidirokastro and Himmaros) are only 15 - 20 km from the Bulgarian border (Dascălu et al. 2012), with the closer Sidirokastro being about 40 km from the species locality in Bulgaria. So, the species most probably has come to Bulgaria as a result of natural dispersal from Greece without assistance of human activity. Usually after its establishment in a new territory this species continues to expand its range (e. g. Cocquempot et al. 2012, del Peral et al. 2017). Therefore, new records in Bulgaria are quite possible. In Europe, X. stebbingi is polyphagous on deciduous trees (Sama 2002). Negative effect of X. stebbingi on the trees has been reported by Braud et al. (2002). Assessment of the impact of the species on forest habitats in Bulgaria is desirable.	en	Gradinarov, Denis, Sivilov, Ognyan (2020): First records of Xylotrechus pantherinus (Savenius, 1825) and X. stebbingi Gahan, 1906 (Cerambycidae: Cerambycinae) in Bulgaria.
