Remarks: A member of the alpinum species group with a type locality on Svalbard, the disjunct distribution of this species includes Arctic, Europe and North America (McInnes 1994 a). The Argentinean record pre-dates the modern taxonomic revision (Pilato & Binda 1998), and therefore requires re-examination.
