This is one of the most northeastern of the North American M. sulphurizona -group species, known from Ontario and Quebec , Canada . It is distinguished by the light-colored halter and the barcode, which differs from that of the most similar species, M. solizona new species by 5.64% minimum p-distance ( Fig. 1 , Table 1 ). This species is in BOLD as BOLD: AAN8707. Distribution. Eastern Canada . Etymology. The name is based on Latin for “snow” ( nivis ), referring to the white color, and “belt”, a play on words as some of this species’ range is in what is called the “snow belt” of the Great Lakes.
