Marine teleost fishes of the northeastern Brazilian coast: 166 years of compiled data

The richness of marine teleost fishes from the tropical northeastern Brazilian coast was compiled through an extensive search of published species records and of voucher specimens in collections. Results are presented in a systematic list that includes 571 marine species across 98 families considered as valid records in coastal and estuarine environments. 516 species (90.4%) are represented by voucher specimens in collections. Species reported in the literature with pending confirmation, or known only from vouchers, may add 72 species to the list, 18 of them without previous mention in the literature representing new records for the study region. Brazilian endemic species are also reported, seven of which are exclusive to the northeastern coast. Additionally, 91 species belonging to 41 families are treated as erroneous or doubtful records for the region, and their geographic distribution or taxonomic status commented upon. Among the valid species recorded, 21 are listed as threatened according to the IUCN Red List and 24 by the Brazilian official list of threatened species. At least four species introduced in the Western Atlantic are now considered invasive in northeastern Brazil. The data presented herein result from the most comprehensive survey of the coastal marine ichthyofauna of northeastern Brazil. It adds 154 species records when compared to the maximum species richness previously reported for the study region in a single publication and serves as a baseline to promote future studies in fish systematics, biogeography, ecology and conservation. Notwithstanding, the species richness of this region remains an underestimate pending additional taxonomic research and the availability of online data for regional collections.
