A recent revision of burrowing mysid taxa in coastal waters on both sides of the American continent, published in this journal by Heard and Price (2006), necessitates a redescription of Chlamydopleon aculeatum Ortmann, 1893 based on type material from the Tocantins estuary on the coast of Brazil. A lectotype is designated and this taxon is revalidated at the species and genus level. The genus Chlamydopleon Ortmann, 1893 gains precedence over the junior synonym Bowmaniella Heard & Price, 2006. The West Atlantic species Gastrosaccus dissimilis Coifmann, 1937 is redescribed based on the types from the coast of Brazil. Regional morphological differences are evident in additional material from 24°S to 34°N. This species and the East Pacific Bowmaniella (Coifmanniella) banneri Bǎcescu, 1968 are transferred to the genus Chlamydopleon, using the new combinations C. dissimile and C. banneri. A key to the acknowledged two genera and seven species of Gastrosaccinae with apically widened third male pleopod is given.
