Until now only six species of lithodids have been found occasionally in the Brazilian coast. Most king crabs are accidentally caught during fisheries targeting other species. Herein we report new records forLithodes confundensandNeolithodesaff.asperrimusfrom the south of Brazil, from the states of Rio Grande do Sul and Santa Catarina, respectively.Lithodes confundensis found in the western Atlantic with a previous northern limit in the Province of Buenos Aires, Argentina.Neolithodesaff.asperrimusis known to occur only along the western coast of Africa in the eastern Atlantic and this is the first record of the species in the western Atlantic.

We present herein the results of a brief field survey of species of Macrobrachium Spence Bate, 1868 in three points of the northern portion of the lower Parnaíba River basin. The northern region of the lower Parnaíba River basin is part of the Environmental Protection Area Delta do Parnaíba and Nauplius, 26: e2018017All content of the journal, except where identified, is licensed under a Creative Commons attribution-type BY.
