Oniscidea was erected by Latreille in 1802. From Schmalfuss (1989), monophytic Oniscidea was accepted, based on derivated characters common to all Oniscidea. Dubioniscidae was erected by Schultz to include the genera Dubioniscus Vandel, 1963, Calycuoniscus Collinge, 1915 and Phalloniscus Budde-Lund, 1908 and the genus Novamundoniscus Schultz, 1995, erected to allocate the american species of Phalloniscus. This study aimed to make the taxonomic review of Novamundoniscus and to produce phylogenetic hipotesis of monophyletic relations of the species that compound this genus, based on morphology, to elaborate a phylogenetic relationship hipotesis among the genera that compounds Dubioniscidae, redescribe known species and describe new ones. This work is presented in a single chapter, divided into two parts, taxonomy and phylogeny of Novamundoniscus. 18 species of Dubioniscus, Novamundoniscus e Phalloniscus were analysed and a data matrix with 73 characters was generated. The final tree revealed Dubioniscidae as monophiletic, but, the validity of the genus Novamundoniscus could not be confirmed. The results of the phylogenetic analyses presented herein are considered provisory and, the taxonomic implications of the topology discussed were not adopted in the taxonomic revision of Novamundoniscus. However, the optimizations of the characters in this topology furnishes important conclusions for the understanding of the evolutive history of the taxa analysed and the characters matrix offers a solid basis for the continuation of this line of research.
