The Australian southern giant crab, Pseudocarcinus gigas (Lamarck, 1818), has traditionally been placed in the families Oziidae Dana, 1851 or Menippidae Ortmann, 1893 (superfamily Eriphioidea MacLeay, 1838). Previous genetic studies questioned the validity of this classification as the molecular markers placed it far from all eriphioid lineages. A morphological re-examination of P. gigas shows that it possesses a suite of unusual characters in the structure of the antennae, antennules, epistome, carapace, pereopods, thoracic sternum, and vulvae that show it is different from other Eriphioidea as well as all other extant heterotremes, confirming the genetic results. A new family, Pseudocarcinidae, and a new superfamily, Pseudocarcinoidea, both monotypic, are here established for P. gigas.

澳大利亚南部巨型螃蟹的新家族和超家族，Pseudocarcinus gigas（拉马克，1818年）（十足目：Brachyura）

澳大利亚南部的巨型螃蟹，Pseudocarcinus gigas（Lamarck（1818）传统上被安置在1851年的Oziidae Dana家族或1893年的Menippidae Ortmann家族中（超家族Eriphioidea MacLeay，1838年）。先前的遗传研究质疑这种分类的有效性，因为分子标记将其远离所有类星体谱系。的形态学复检P.牡蛎表明，它具有一个套件的不寻常的字符在触角，触角，epistome，甲壳，pereopods，胸胸骨，和外阴的结构显示它是从其他酋妇蟹总科不同以及所有其他现存的异源，证实了遗传结果。在这里为毕加索氏杆菌建立了一个新的家族，假单胞菌科，和一个新的超家族，假单胞菌科。
