Abstract
In the main channel of the Upper Paraná River, four sampling sites were established according to the profile of the bottom. Samples were carried out monthly from July 1993 to February 1995 with a modified Petersen grab. Four species were found at four sites: Potamocaris bifida, P. bidens, P. bidentata and P. tridentata. Canonical correspondence analysis indicated differences in the preferred microhabitats of the Potamocaris species, mainly in regard to sand particle size in the main river channel. Bedform stability was the most important factor affecting the abundance of this community.
