North American specimens of this species were misidentified as T. globulifer until Newton (1987) clarified the matter, and reported that all previous North American records of T. globulifer were actually T. melanarius or T. winkleri (Bernhauer). Tasgius melanarius has been collected on both east and west coasts and was taken as early as 1935 in Québec. The Québec record is still the oldest known and T. melanarius has since expanded its range in eastern North America. Consequently, T. melanarius is here newly recorded from New York, Vermont, and Maine. Its distribution in ECAS is given by Map 30.
