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.... |

A descoberta recente, no fundo rochoso do Rio Piquiri, Bacia do Paraná, Brasil, de Sterrastrolepis brasiliensis Volkmer-Ribeiro & De Rosa-Barbosa, 1978, uma espécie de esponja continental ameaçada, possibilitou o registro fotográfico de espécimes vivos, o aperfeiçoamento das ilustrações ao MEV e da descrição de algumas características, a descrição do habitat e o registro de uma assembléia de esponjas composta por S. brasiliensis, Oncosclera navicella (Carter, 1881) e Oncosclera tonolli (Bonetto & Ezcurra de Drago, 1968). Oncosclera tonolli tem seu primeiro registro para águas brasileiras e para a Bacia do Paraná. Gêmulas de O. navicella são tambem ilustradas ao MEV. |

An extensive survey for freshwater sponges was carried at the temporarely exposed rocky bottoms of river Corumbá at Goiás State and river Manso at Mato Grosso State. The exposure resulted from the closing of the dams for lake formation at the respective Hidreletric Power Plants. Drulia uruguayensis Bonetto & Ezcurra de Drago, 1968, Corvospongilla seckti Bonetto & Ezcurra de Drago, 1966 and Trochospongilla repens (Hinde, 1888) were seen to be common to both rivers. Eunapiusfragilis (Leidy, 1851), Oncosclera navicella (Carter, 1881) and O. petricola (Bonetto & Ezcurra de Drago, 1969) were yet found in river Manso and O. schubarti (Bonetto & Ezcurra de Drago, 1967) in river Corumbá. O. schubarti is redescribed and SEM... |
