THREE NEW ONTARIO BLACK FLIES OF THE GENUS PROSIMULIUM (DIPTERA SIMULIIDAE) AND OBSERVATIONS ON THEIR ECOLOGY

Abstract

Cytological studies have exposed new species complexes in the dipterous family Simuliidae. A study of one of these in the genus Prosimulium has established morphological, distributional and ecological characteristics of three of its members and they have been described as new species. A comparison has been made between those and other members of the complex throughout the world.
