03EB87A1FFFEFFDCFCDFFEFCE59DFAB2.taxon	diagnosis	Diagnosis. Platycheirus jaerensis belongs to the P. peltatus group (Van Steenis & Goeldlin de Tiefenau, 1998; Bartsh et al., 2009; Young et al., 2016). In Europe, female of this species is most similar to P. amplus Curran, 1927, P. holarcticus Vockeroth, 1990, P. peltatus (Meigen, 1822) and P. nielseni Vockeroth, 1990 in having fore and mid femora entirely yellow (in similar P. islandicus Ringdahl, 1930 and P. parmatus Romani, 1857, fore and mid femora with a broad black ring). Platycheirus jaerensis can be separated from P. amplus and P. holarcticus by tergite 2 with large rhomboid maculae (Fig. 2) that reach or almost reach the anterior corners of the tergite (in P. amplus and P. holarcticus, tergite 2 with small lunular to reniform maculae that not reach the anterior corners of the tergite). From similar P. peltatus (Figs 5 – 7) and P. nielseni it can be clearly distinguished by the yellow scape and pedicel (Figs 3, 4) (in P. peltatus and P. nielseni, scape and often pedicel black, as on Figs 6, 7); paired yellow abdominal maculae at most with faint silvery pruinescence (in P. peltatus and P. nielseni, paired yellow abdominal maculae with heavy silvery pruinescence). These characters were based on Bartsh et al. (2009) and Van Veen (2010).	en	Prokhorov, A. V. (2019): New records of the hoverflies (Diptera: Syrphidae) from Russia.

Russia: Moscow Region, Tabolovo env., 55.913381 N 36.068807 E, edge of mixed forest, 17.06.2017, on flowers of Anthriscus sylvestris, 1 ♀ (A. Prokhorov).	en	Prokhorov, A. V. (2019): New records of the hoverflies (Diptera: Syrphidae) from Russia. Ukrainska Entomofaunistyka (Oxford, England) 10 (2): 17-22, DOI: 10.5281/zenodo.3585582, URL: http://dx.doi.org/10.5281/zenodo.3585582
03EB87A1FFFEFFDFFCDFFA63E0DEF9EE.taxon	distribution	Distribution: at present uncertain, due to confusion with X. pedissequum (Harris, 1776) and X. stackelbergi Violovitsh, 1975, but authentically known from Andorra, Czech Republic, France, Germany, Hungary, Italy, the Netherlands, Norway, Poland, Portugal, Slovak Republic, Slovenia, Spain, Switzerland (Belcari et al., 1995; De Groot & Govedič, 2008; Mielczarek, 2009; Tóth, 2011; Van Eck, 2011; Van Steenis, 2011; Ricarte & Marcos-García, 2017; Nedeljković et al., 1918; Speight, 2018; Syrphidae checklists, 2019); Ukraine (Prokhorov et al., in press), Russia (first record).	en	Prokhorov, A. V. (2019): New records of the hoverflies (Diptera: Syrphidae) from Russia. Ukrainska Entomofaunistyka (Oxford, England) 10 (2): 17-22, DOI: 10.5281/zenodo.3585582, URL: http://dx.doi.org/10.5281/zenodo.3585582
03EB87A1FFFEFFDFFCDFFA63E0DEF9EE.taxon	diagnosis	Diagnosis. Three species of the genus, X. dives, X. pedissequum and X. stackelbergi, are very similar in appearance. Common characters for them are: the tergite 2 wider than long; alula entirely covered in microtrichia; eye pile very sparse, shorter than the diameter of the anterior ocellus; hind femora black on the apical fourth. Xanthogramma dives can be easily separated from X. pedissequum by the thorax with more than two yellow maculae laterally (in X. pedissequum, thorax with one or two yellow maculae laterally). From X. stackelbergi, it can be distinguished by wing cells r 1 and r 2 + 3 darkened in the apical part (in X. stackelbergi, wing cells r 1 and r 2 + 3 hyaline in the apical part). These characters are based on Nedeljković et al. (1918).	en	Prokhorov, A. V. (2019): New records of the hoverflies (Diptera: Syrphidae) from Russia.
