Mesocyclops ogunnus is a copepod originally recorded in Africa and Asia, being considered an invader species in reservoirs in the Americas. The present work records its occurrence in northeastern Brazil for the first time. This species was collected in the Três Lagoas region in the city of João Pessoa, State of Paraíba, Brazil, which increases its geographical distribution beyond the central-western, southeastern and southern regions of the country.
