Abstract
The polychaete fauna from the mangroves of the Amazon Coast in Maranhão state, Brazil, is reported in this study. Fourteen species are listed, namely Alittasuccinea (Leuckart, 1847); Arabella (Arabella) iricolor Montagu, 1804; Capitellacapitata (Fabricius, 1780) complex; Exogone (Exogone) breviantennata Hartmann-Schröder, 1959; Heteromastusfiliformis (Claparède, 1864); Isoldapulchella Müller, 1858; Mediomastuscaliforniensis Hartman, 1944; Namalycastisfauveli Nageswara Rao, 1981; Namalycastisgeayi (Gravier, 1901); Namalycastissenegalensis (Saint-Joseph, 1901); Nephtyssimoni Perkins, 1980; Paraonisamazonica sp. n.; Sigambrabassi (Hartman, 1945); and Sigambragrubii Müller, 1858. Among them, Namalycastisfauveli and Namalycastisgeayi are recorded for the first time in Brazil. Paraonisamazonica sp. n. is a new species for science, characterized by a rounded prostomium, 4–8 pairs of foliaceous branchiae, absent eyes, and two types of modified neurochaetae, acicular and hook-shaped.
