description: <i>Orthonevra geniculata</i> (Meigen, 1830) (FIgs 22–25) Material examined. Ukraine. Kyiv Region: Dibrova env., 50.19 N 30.20 E, 3.05.2014, 1 &amp;female; (M. Zaika). D i s t r i b u t i o n. Norway, Sweden, Finland, Ireland, Great Britain, Denmark, the Netherlands, Belgium, France, Northern Italy, Germany, Poland, Czech Republic, Slovakia, Hungary, Romania, Bulgaria, Russia (European territory, West and East Siberia, Far East) and Mongolia (Stackelberg, 1953; 1970; Peck, 1988; Holinka &amp; Mazánek, 1997; Mutin &amp; Barkalov, 1999; Tóth, 2011; Speight, 2017; Mielczarek, 2018), Ukraine (<b>first record</b>). Diagnosis. <b>Female</b> differs from <i>Orthonevra erythrogona</i> (Malm, 1863) by legs with tibiae pale at least for basal 1/3 (almost half in the specimen from Kyiv Region, as on FIg. 23), and the basoflagellomere about 3 times longer than wide (FIg. 24) (in <i>O. erythrogona</i>, tibiae black with only knees pale, and the basoflagellomere twice as long as wide). From similar <i>Orthonevra elegans</i> (Wiedemann in Meigen, 1822) <i>O. geniculata</i> differs by eyes without dark stripe, and the basoflagellomere about 3 times longer than wide (in <i>O. elegans</i>, eyes with dark stripe, and the basoflagellomere about 4 times longer than wide). From similar <i>O. intermedia</i> Lundbeck, 1916 and <i>O. stackelbergi</i> Thompson &amp; Torp, 1982 <i>O. geniculata</i> differs by the crossvein r-m brown infuscate and two-colored pterostigma (yellowish with dark part at base) (FIg. 25), face on the level of the antennal sockets about 1.5–2 times as wide as width of an eye (FIg. 24) (in <i>O. stackelbergi</i> and <i>O. geniculata</i>, the crossvein r-m clear, pterostigma unicolorous, the width of the face on the level of the antennal sockets less than the width of an eye) (Stackelberg, 1953; Van Veen, 2010).
