摘要巴西南部马夫拉南里约组Campáleo露头（二叠纪，Asselian-Sakmarian）的Lontras页岩中首次发现了代表Hexactinellida的二叠纪海绵。该虫隶属于Hemophelcellidae，并被鉴定为Microhemophelia greinertin。该化石代表了巴西古生代有节海绵的第一个记录，也是该属已知的第二个物种。此外，它增加了对Hemaprocosa的了解，Hemaprocosa是一个单型群，主要由简单的特征定义，在这里被认为包括一个科，Hemaprocellidae（宾夕法尼亚-白垩纪），和两个属，Hemaprocella和Microhemaprocella。
Abstract The first-described articulated Permian sponge from Brazil, representing Hexactinellida, has been recovered from the Lontras Shale in the Campáleo outcrop (Permian, Asselian–Sakmarian), Rio do Sul Formation, Mafra, in southern Brazil. It is assigned to the Hemidiscellidae and identified as Microhemidiscia greinerti n. sp. This fossil represents the first record of articulated sponges in Brazil from the Paleozoic Era, as well as the second species known from this genus. Moreover, it increases knowledge of the order Hemidiscosa, a monotypic group mostly defined by simple characters, which is here considered to comprise one family, Hemidiscellidae (Pennsylvanian-Cretaceous), and two genera, Hemidiscella and Microhemidiscia.
