Abstract
Brugia beaveri sp. n., from the lymph nodes, skin, and carcass of the raccoon (Procyon lotor) in Louisiana is described. This is the first Brugia species to be reported from mammals in North America. It differs from the six other described species of the genus generally in the smaller body size of the female, the size and structure of the spicules, and the larger microfilaria which has a distinctively long cephalic space.
