Abstract

Oncholaimus cobbi was described from the Brazilian coast. The area studied, Coroa Grande, is located in Sepetiba Bay, State of Rio de Janeiro, Brazil. Sampling was carried out monthly, from May 1998 through April 1999. Most of the population was represented by adults, of which non-ovigerous females were the most abundant category. The species reached its highest population density during the warmest months, and the highest densities of males and ovigerous females were seen in February 1999.
