Remarks: Species reported from Greenland (locus typicus), Arkansas, Alaska, Mongolia (Kaczmarek & Michalczyk 2006 a, Land et al. 2012, Johansson et al. 2013), and the southern tip of South America. Most of the localities have cold climate which may suggest specific habitat preferences, but the highly disjunct distribution could support the South American specimens belonging to a new species (see Michalczyk et al. 2012 a,b for more details).
