Sarcoglanidinae and Glanapteryginae catfishes are among the most unusual elements of the Neotropical freshwater fish fauna. Microcambeva ribeirae, M. barbata and M. draco are miniaturized Sarcoglanidinae known to occur in sandy microhabitats in drainages of the Brazilian Atlantic Forest. Due to their specific habitats, specimens of Microcambeva are rare in fish collections, and new records are considered noteworthy to warrant report. Recently, specimens of this genus were newly found in the Rio Doce basin in Minas Gerais and Espírito Santo States. Such new records expand the known geographic distribution of Microcambeva. Further records of Microcambeva for Rio Peruípe in south Bahia State are also reported. Comments on the distribution of Microcambeva species along the Atlantic Forest coastal basins and suggestions on its conservation status are also offered.

The genus Ransonia Blandin, 1979 (Arachnida: Araneae) was established with description of a new species, Ransonia mahasoana of the family Pisauridae (Arachnida: Araneae) endemic from Mahasoa, Madagascar. Unfortunately, this name is preoccupied by Ransonia Kramp, 1947, a genus of the family Rhopalonematidae (Hydrozoa: Trachymedusae) with only one species, Ransonia (Aglantha) krampi Ranson (1932), from Gibraltar, Mediterranean. According to article 60 of the International Code of Zoological Nomenclature a new substitute name is necessary, since Ransonia Blandin, 1979 does not have a junior synonym applicable and is a junior homonym of another genus. Therefore, we propose a replacement name for the spider genus as follows.
