Nemoura viki Lillehammer 1972

Finnmark, Kautokeino, Emmatjernbekken , 29.vi.1972, 55 imagos, leg. A. Lillehammer [labelled P2694: ethanol, specimens stored individually in numbered vials, together with their detached right forewing; slide-mounted epiprocts specimens no. 49-52]; slidemounted epiproct of an additional, unlabelled specimen .

Only records from northernmost parts of Finland and Norway were known to Lillehammer (1988:118). Later, Johansson and Nilsson (1989, 1994) reported isolated finds of N. viki from the Swedish province of Västerbotten, 500 km south of the previously reported distribution. The Artskart database includes two collection-based records from the province of Troms in northern Norway. In all, there are very few records of this taxon. By all likelihood all specimens at the NHM have been identified by Lillehammer, but this is not documented. One of the slide-mounted epiprocts is shown in Fig. 3 . The type specimens of N. viki appear to be missing (see below). The specimens used for the description of the nymphs (Lillehammer 1986) have not been located either.
