| The Cemitério Paleolake, Catalão, Goiás, is a lacustrine deposit that is rich in spicules of continental sponges. These spicules, which are present in three sections (1-3), were analyzed for the taxonomic identification of the species in order to reconstruct the late Quaternary palaeoenvironment. An indigenous assemblage of lentic sponges was found, consisting of Metania spinata (Carter 1881), Dosilia pydanieli Volkmer-Ribeiro (1992), Radiospongilla amazonensis Volkmer-Ribeiro and Maciel (1983), Trochospongilla variabilis Bonetto and Ezcurra de Drago (1973), Corvomeyenia thumi (Traxler 1895), Heterorotula fistula Volkmer-Ribeiro and Motta (1995), plus Corvoheteromeyenia australis (Bonetto and Ezcurra de Drago 1966), which here has its first record in an... |

| 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.... |
