RESUMO
A new species in the previously monotypic genus Xiphoniscus Vandel, 1968, X. adisi sp. nov. is described. Both X. mirabilis Vandel, 1968 from Ecuador and X. adisi sp. nov. from Brazil occur in the Amazon rainforest. The new species shows a prolonged coxal plate II drawn out caudally, an autapomorphy of Xiphoniscus. Xiphoniscus adisi sp. nov. differs from X. mirabilis mainly in the characteristics of buccal appendages and male pleopods. A diagnosis of the genus Xiphoniscus is provided. The species Androdeloscia escalonai is reported from the Brazilian Amazon for the first time.

The new subfamily Iuiuniscinae, Styloniscidae, is erected for the new genus Iuiuniscus and the new species I. iuiuensis, which is described from cave of the State of Bahia, Northeastern Brazil. A special ecological character is shown here for the first time for a New World Oniscidea: the construction of mud shelters. An introduction addressing the systematics of Synocheta with emphasis on Styloniscidae Vandel, 1952 is provided, as well as general comments about the dependence of water in some Oniscidea and ecological traits of amphibious Synocheta. The problems referring to nomenclature, taxonomy and the interrelationships in Styloniscidae are discussed.
