Polytene chromosomes and phylogenetic relationships of Chironomus atrella (Diptera: Chironomidae) in North America
The identity of Chironomus atrella Townes has been confusing because the name has been used for at least 2 quite different species. This situation is clarified karyosystematically by describing the banding patterns and chromosomal polymorphisms from a number of locations in Canada and the US. Most p...
