| Summary: | J\xc3\xa4derholm\'s type of Schizotricha antarctica, collected by the Swedish Antarctic Expedition 1901-1903, is redescribed from a syntype in the collections of the Swedish National Museum, Stockholm. The type lot of that species proved to be composite, the material best resembling J\xc3\xa4derholm\'s (1904, 1905) descriptions and figures has been designated as the syntype. There are two more species in the type lot, that have also been described, but are too poorly represented to be either recognized as one of the described species of Oswaldella or to merit a new specific name; they have been indicated as Oswaldella spec. 1 and spec. 2.\nResumen: Se ha revisado y redescrito el material tipo de Schizotricha antarctica J\xc3\xa4derholm, 1904, recogido durante la Swedish Antarctic Expedition 1901-1903 y depositado en el Swedish Museum of Natural History de Stockholm. Dicho material ha resultado estar compuesto por tres especies. Se ha elegido como sintipo de Oswaldella antarctica la especie m\xc3\xa1s pr\xc3\xb3xima a la descripci\xc3\xb3n y figuras de J\xc3\xa4derholm (1904, 1905). Las otras dos especies est\xc3\xa1n tan pobremente representadas que no es posible adscribirlas a ninguna especie conocida de Oswaldella ni asignarles un nuevo nombre espec\xc3\xadfico, con lo que se denominan Oswaldella spec. 1 y spec.2.
