The genus Crenea consists of two species, Crenea maritima and C. patentinervis, restricted to the coasts and estuaries of northern South America from Colombia to Pará in Brazil. Taxonomic studies dealing exclusively Crenea are few. This study reports a new record for Crenea maritima in the Delta of the Rio Parnaíba (Piauí and Maranhão states, Brazil), as well as characterizing the morphology, taxonomy and ecology of this species. The illustrations was based on the main diagnostic characters of the species as observed in the collected samples.

Key words:
