RESUMO
Two new species of the genus Isotomiella Bagnall, 1939 are described and illustrated, the first: Isotomiella macedoisp. n., based on males and females, from the "Parque Nacional da Serra dos Órgãos" (Teresópolis municipality, State of Rio de Janeiro) differs from the other by tibiotarsus III thickened and blunt and two antero-lateral chaetae of labrum strongly thickened. The second species Isotomiella uaisp. n. from "Serra da Gandarela", (Caeté municipality, State of Minas Gerais) differs from the other by presence of short sensilla on antennal IV and tergites, two anterolabral chaetae thickened and falcate mucro.
RESUMO
A new species of Tyrannoseira Bellini & Zeppelini, 2011 (Entomobryidae) is described and illustrated. Specimens of T. diabolica sp. nov. were collected in Barreira do Inferno, state of Rio Grande do Norte, Brazil. This is the fourth described species in the genus. All males of Tyrannoseira have the femora of the first pair of legs enlarged and slender tibiotarsi, both bearing several spine-like setae. Probably the closest species to T. diabolica sp. nov. is T. sex Bellini & Zeppelini, 2011. They share many similarities in their color pattern and dorsal chaetotaxy.

RESUMO
Seira Lubbock, 1869 is the most speciose genus of Collembola in Brazil. Herein, we describe and illustrate a new species of Seira, Seira ritae sp. nov., collected in João Pessoa, state of Paraíba, Brazil, in an urban seaside area. The new species shows many similarities with S. mendoncea Bellini & Zeppelini, 2009 especially in what concerns the dorsal distribution of the macrochaetae of the head, the metathorax, and the first three abdominal segments. However, the two species can be distinguished by the chaetotaxy of the mesothorax and abdominal segment IV. The type locality of the species probably indicates some level of natural resistance to the impacts associated with human activities.

RESUMO
A new species of Xenylla Tullberg, 1869, X. capixaba sp. nov., is described and illustrated. In addition, we present a list with new records of Poduromorpha from the state of Espírito Santo, Brazil. Xenylla yucatana Mills, 1938 and Brachystomella platensis Najt & Massoud, 1974 are for the first time recorded in Brazil. Also, the distributions of B. ceciliae Fernandes & Mendonça, 2004, B. contorta Denis, 1931 and Arlesia albipes (Folsom, 1927) are expanded to include Espírito Santo. Brachystomella agrosa Wray, 1953, previously recorded in agricultural soils, was also found in a marine environment.

RESUMO
A new species of Entomobryidae of the genus Seira Lubbock, S. paraibensis sp. nov. is described and illustrated. The type locality of the species is the municipality of Areia, state of Paraíba, Brazil. The species was found inhabiting the Atlantic forest litter and top soil environment. S. paraibensis sp. nov. resembles S. pseudoannulata in many morphological features. This is the sixth species of the genus found and described in Paraiba so far. A key with the 11 species of Seira registered so far in Paraíba is provided. Also a list with all species of the genus from Brazil is presented.
