- <p><i>Euura cornuta</i> (Lindqvist, 1962)</p><p><b>Material examined.</b></p><p>Greenland. South-East Greenland, Skjoldungen “ Bygden ” • 1 ♀ (NHMD), 19–27 July 1992, S. Andersen leg. Northeast Greenland, Zackenberg Research Station (74.467, –20.567) • 1 ♀ (SYKE; grhym-00070), 11 June 2010, T. Roslin leg.</p><p>This is the species called <i>Amauronematus viduatus</i> by Henriksen (1939) and <i>A. nitidipleuris</i> by Vilhelmsen (2015). Two examined females (one in Fig. 3) fit well morphologically with <i>E. cornuta</i> (black pronotum, tegula, and cerci; partly pale clypeus and malar space), but not the other known European <i>Euura viduata</i> group species.</p><p><b>Genetics.</b></p><p>The COI of two specimens from Northeast Greenland (Zackenberg Research Station; grhym- 00070 and ZA 2011- 523 in BOLD) are identical to each other and 2.4–2.5 % different from European <i>E. cornuta</i>. Based on COI, <i>E. cornuta</i> is the most distinct within the <i>Euura viduata</i> group (about 7 % different from the other species). However, the closest sequences to the Greenland specimens (minimum divergence of 0.15 %) are unidentified <i>Euura viduata</i> group specimens from Canada (including Ellesmere Island) that may include species other than <i>E. cornuta</i> (a female BIOUG 16993 - E 11 from Yukon in BOLD has an extensively pale pronotum and tegula).</p>
