| Seira caerucinerea sp. nov. , a new species of springtail from the Cerrado domain, state of Tocantins, Brazil, is described and illustrated. The new species is mainly characterized by bluish-gray coloration and dorsal chaetotaxy presenting macrochaeta S7 on head, three macrochaetae (a6, m6 and p6) on margin of metathorax and 4+4 macrochaetae (a1, m2, m3 and m4i) on abdomen I. Characteristics of maxillary and labial papillae, chaetotaxy of subcoxae, collophore, ventral region of head, ventral and lateral region of abdomen IV and V, which are usually omitted in species descriptions within the genus, are also provided. This is the first species of Seira described from the Cerrado domain, as well as the first record of the genus from the state of Tocantins. |

| 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. |

| ABSTRACT Xestoblatta Hebard, 1916 is revisited, with description of X. urucuana sp. nov. from northern Brazil. Additionally the hitherto known species X. amaparica Rocha e Silva Albuquerque & Gurney, 1962, X. surinamensis Bruijning, 1959 and X. vera Rocha e Silva Albuquerque & Fraga, 1975, are redescribed. Information on the genitalia of the males is also provided. All the species are included in the Xestoblatta surinamensis species group and the placement of X. jygautieri Grandcolas, 1992 in this group discussed. To facilitate species identification, we provide a key to the species of the X. surinamensis group, charac terized by the subgenital plate with left style (ventral view) about two to five times larger than right style; right paraproct... |

| A new species of Tipuana Melichar, 1926, T. similis sp. nov., is described and illustrated based on specimens from the state of Amazonas, northern Brazil. The new taxon is externally very similar to T. chirensis Young, 1977. It can be distinguished from the latter and from the other known species of the genus mainly by the aedeagus with a triangular, posteriorly directed projection between the basidorsal apodemes, and with shaft not expanded apically and bearing two sharp, short apical processes curved dorsally. Diagnostic features of the new species are also found in the paraphysis, which is symmetrical, expanded towards the apex and with a round apical excavation. A key to the species of Tipuana (males) is added. |

| 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. |

| A singular group of 19 species of Neotropical Trichomyia Haliday in Curtis, 1839 presents four segments in the palpus, the first two partially fused; five of these species were included in the subgenus Opisthotrichomyia Bravo, 2001 and seven in the subgenus BrachiotrichomyiaBravo & Araújo, 2013. A new species from Brazil is described and a new subgenus proposed for four Neotropical species of this morphological group: T. biloba Quate, 1999 from Panama, and T. onorei Bravo, 2002, T. queirozi Bravo, 2002 and T. horrida sp. nov. from Brazil. Syntrichomyia subgen. nov. can be recognized by its fused gonocoxites and gonostyli, and by its bilobed hypoproct. A key to the known species (males) of this new subgenus is presented. |
