          Abstract

          Dosilia plumosa (Carter, 1849), type species of the genus, and D. brouni (Kirkpatrick, 1906), with distribution respectively in the Oriental and Ethiopic regions, are revised based on a SEM analysis of spicules, gemmules and skeletal structure. The lectotype here designated for D. plumosa is illustrated as well as the holotype by monotypy determined for D. brouni. Dosilia palmeri (Potts, 1885) and D. radiospiculata (Mills, 1888) distributed in the Nearctic and Neotropical regions and D. pydanieli Volkmer-Ribeiro, 1992, found in the Neotropical region, are revised based on a SEM analysis of spicules, gemules and skeletal structure. The holotype by monotypy is determined for D. radiospiculata. Heteromeyenia plumosa Weltner,1895 is synonymyzed with D. radiospiculata. Upon the revision of its five species, the genus is redefined and a key presented.

          Translated abstract

          Dosilia plumosa (Carter, 1849), espécie-tipo do gênero e D. brouni (Kirkpatrick, 1906), com distribuição respectivamente nas regiões Oriental e Etiópica, são revisadas após estudos ao MEV de seus conjuntos espiculares, gêmulas e estrutura do esqueleto. São ilustrados o lectótipo selecionado para D. plumosa e o holótipo por monotipia determinado para D. brouni. Dosilia palmeri (Potts, 1885) e D. radiospiculata (Mills, 1888) com distribuição nas Regiões Neártica e Neotropical e D. pydanieli Volkmer-Ribeiro, 1992, com ocorrência na Região Neotropical são revisadas após estudos ao MEV de seus conjuntos espiculares, gêmulas e estrutura do esqueleto. Holótipo por monotipia é estabelecido para D. radiospiculata. Heteromeyenia plumosa Weltner, 1895 é sinonimizada com D. radiospiculata. A revisão das cinco espécies do gênero é concluída com a sua redefinição e apresentação de chave taxonômica.
