The family Rhynchocinetidae Ortmann (Crustacea, Decapoda, Caridea) on the Brazilian coast

The family Rhynchocinetidae Ortmann, 1890, presently in the superfamily Nematocarcinoidea Smith, 1884 and the genus Rhynchocinetes H. Milne Edwards, 1837, has always had a complex and controversial classification. Until recently, the only species known from the Brazilian coast was Rhynchocinetes rigens Gordon, 1936, which was transferred to the genus Cinetorhynchus. Rhynchocinetes typus H. Milne Edwards, 1837, the type-species of the genus, was known only from the eastern Pacific; but in the carcinological collection of the Museu de Zoologia da Universidade de Sao Paulo, a specimen of this species collected at Ubatuba, Sao Paulo was found; this is the first record of this species for the Brazilian coast. These two species are redescribed and illustrated.
