Synonyms and other taxonomic changes
Chironomus nivoriunda Fitch, 1847
The original description is inadequate to distinguish niviorunda from other Chironomidae active in the winter. Without evidence to the contrary, workers apply his name to the most common species in New York, the original location where he found the species.
Explanation of Names
"Snow-born midge"
Identification
One of a few species with a very long anal point. The triangular gonostylus is distinctive.

One other species may, rarely, have a gonostylus that is a right triangle rather than isosceles.
Range
Minnesota to Newfoundland, south to northern Alabama. Records outside this region are probably the result of confusion with other species.
Remarks
"D. nivoriunda is the most common northeastern species of Diamesa. It is sometimes taken with cheimatophila in the Northeast and with mendotae in the Midwest. The emergence period is from September to May." (Hansen and Cook, 1976)
