description: <i>Xanthogramma laetum</i> (Fabricius, 1794) (fig. 29) M a t e r i a l e x a m i n e d. Ukraine. Zakarpattia Region: Kamianytsia env., 48.70 N 22.43 E, Uzh River valley (left bank), 9– 10.05.2017, roads in deciduous forest, 4 &amp;female; (A. Prokhorov). Distribution: from northern Germany south to south-west France, and from Belgium eastwards through central and southern Europe (Germany, Poland, Italy, former Yugoslavia) to Czech Republic, Slovakia, Hungary, Romania, Bulgaria and central part of European Russia (Peck, 1988; Holinka &amp; Mazánek, 1997; Tóth, 2011; Speight, 2017; Mielczarek, 2018); Ukraine (first record). Diagnosis. It easily differs from the other European species of the genus by the distinctly haired eyes, the hairs longer than the diameter of the anterior ocellus (in other species, the eye hairs very sparse, no hairs longer than the diameter of the anterior ocellus). <i>Xanthogramma laetum</i> is similar to <i>X. marginale</i> (Loew, 1854) only in having yellow transverse fasciae on tergite 3, but can be separated from it by the tergite 2 wider than long, tergite 4 with a transverse yellow fascia and the alula entirely covered by microtrichia (in <i>X. marginale</i>, tergite 2 longer than wide, tergite 4 with a pair of transverse yellow marks and the alula extensively bare) (Violovitsh, 1975; Speight &amp; Sarthou, 2017). We are very grateful to Volodymyr Roshko (Uzhhorod National University, Uzhhorod), for his kind assistance in organizing a collecting trip to Zakarpattia Region in 2017. We also thank Valery Korneyev (Institute of Zoology of NAS of Ukraine, Kyiv) for valuable scientific and editorial comments. The authors are grateful to Alex Gumovsky (Institute of Zoology of NAS of Ukraine, Kyiv) for the opportunity to use the Leica microscope system for imaging. The authors thank Tore Nielsen (Sandness, Norway) for his valuable comments on <i>Platycheirus nielseni</i>. The authors would like to thank two anonymous reviewers for their valuable contributions to the manuscript.
