| In the first paper of this series (Albuquerque & Brandão, 2004) we revised the Vezenyii species group of the exclusively Neotropical solenopsidine (Myrmicinae) ant genus Oxyepoecus. In this closing paper we update distribution information on the Vezenyii group species and revise the other Oxyepoecus species-group (Rastratus). We describe two species (Oxyepoecus myops n. sp. and O. rosai n. sp.) and redescribe previously known species of the group [O. daguerrei (Santschi, 1933), O. mandibularis (Emery, 1913), O. plaumanni Kempf, 1974, O. rastratus Mayr, 1887, and O. reticulatus Kempf, 1974], adding locality records and comments on the meagre biological data of these species. We also present an identification key to Oxyepoecus species based on workers. |

| Resumo. Entre as espécies de formigas economicamente importantes, devido aos danos que muitas vezes causam à agricultura, as mais significativas são as formigas-cortadeiras por possuírem o hábito de cortar e transportar fragmentos vegetais diversos para os seus ninhos subterrâneos. O objetivo deste estudo foi caracterizar alguns aspectos ecológicos de Atta sexdens piriventris Santschi no município de Capinzal, estado de Santa Catarina, Sul do Brasil. O material de origem vegetal transportado pelas formigas apresentou como característica folhas verdes/frescas 57%, folhas secas 23%, pedaços de frutos 7%, sementes 7% e flores 3%. Já os de origem animal tiveram uma representação de 3%, e eram compostos por pedaços de insetos. A média de distância percorrida... |

| Studies on lower attines are scarce, especially on nesting and foraging ecology and behavior. This study aimed to contribute to the knowledge of an Attini in dunes ecosystems through the description of density and spatial distribution of Mycetophylax simplex (Emery, 1887) nests in a strip of mobile dunes in the Praia Grande beach, Torres, northern coast of Rio Grande do Sul, Brazil. The density and spatial distribution of nests were estimated in four plots of 2,500 m² each, in which were found 20, 209, 284 and 324 nests, with average densities of 0.01 nests/m², 0.09, 0.11 and 0.13 nests/m², respectively. The nests were found near to the vegetation and showed clumped distribution. The density and distribution pattern of the nests seem to be related to the... |

| I hereby revise, for the second time, the primarily Neotropical solenopsidine ant genus Megalomyrmex, describing M. wettereri n. sp., of the Silvestrii group, based on workers and gynes. Megalomyrmex latreillei Forel is synonymyzed under M. foreli Emery. The gyne of M. poatan is described and that of M. wallacei redescribed; males of M. acauna, M. incisus and M. wallacei are described. New locality records are given for M. ayri, M. cupecuara, M. goeldii, M. iheringi, M. modestus, and M. wallacei (Modestus group); M. acauna, M. balzani, M. cyendyra, M. emeryi, M. foreli, M. glaesarius, M. leoninus, M. staudingeri, and M. timbira (Leoninus group); M. poatan, M. silvestrii, and M. symmetochus (Silvestrii group), and M. drift, M. incisus, M. myops and M.... |

| Using of toxic baits made of dehydrated citric pulp to control grass-cutting ants can lead to unsatisfactory results because of the low attractiveness of the substrate to worker ants. This work aimed to identify attractive substances, with potential for incorporation in a matrix of granulated baits for grass-cutting ants, among several kinds of sugars and substances used in artificial sweeteners. Experiments were carried out in mature nests of Atta capiguara (Hym.: Formicidae) set in pasture. Studied substances were sucrose, fructose, soluble starch, raffinose, maltose, lactose, sorbose, cellobiose, arabinose, xylose, glucose, galactose, rhamnose, arabinose, melezitose, saccharine and cyclamate (at 5.0% w/v). Later, on maltose, xylose, sucrose, fructose... |

| Mycetarotes is a small genus of the exclusively Neotropical fungus-growing ants, that includes M. parallelus (Emery), M. senticosus Kempf, M. acutus Mayhé-Nunes and M. carinatus Mayhé-Nunes. We hereby revise historical and recent information regarding Mycetarotes species for the first time, providing an identification key to workers, diagnoses, synoptic illustrated redescriptions of the species, including those of sexuals when known, updates of distributional records, and nest pictures of M. carinatus and M. parallelus. We comment the taxonomy and phylogenetic relationships among Mycetarotes and related genera, and on their geographical distribution. The available biological information on the genus is summarized. |

| We present here a list of the Attini type material deposited in the Formicidae collection of the Museu de Zoologia da Universidade de São Paulo (MZSP), Brazil. In total, the Attini (fungus-growing and leaf-cutting ants) collection includes types of 105 nominal species, of which 74 are still valid, whereas 31 are considered synonyms. The majority of the types in the MZSP collection are syntypes (74), but in the collection there are 4 species represented only by holotypes, 12 by holotypes and paratypes, 13 species only by paratypes, and 2 species by the lectotype and one paralectotype as well. All holotypes and paratypes refer to valid species. The aim of this type list is to facilitate consultation and to encourage further revisionary studies of the Attini... |

| Abstract: The objective of this work was to survey soil ants in Bt and non-Bt maize (Zea mays) crops, and to compare their effect on the soil ant community. Nine pitfall traps, 10 m apart, were installed in a central area (900 m2) of each of the following treatments (2,500 m2): conventional maize; maize modified with the Cry1F, Cry1Ab, and Vip3A proteins; and a native vegetation area. Fortnightly collections were conducted during four periods (complete producing cycles) of the crop, from 2011 to 2013. The number of ant species varied from 25 in Bt maize (Vip 3A) to 58 in Bt maize (Cry 1F). The treatment with conventional maize showed the highest Shannon-Wiener diversity index (H’ = 2.60). Jaccard’s index showed that there is dissimilarity between the... |

| The present catalogue lists ant types of 12 traditional Myrmicinae ant tribes (Adelomyrmecini, Basicerotini, Blepharidattini, Crematogastrini, Formicoxenini, Lenomyrmecini, Myrmicini, Phalacromyrmecini, Pheidolini, Stegomyrmecini, Stenammini and Tetramoriini) housed in the Formicidae Collection of the Hymenoptera Laboratory, Museu de Zoologia da Universidade de São Paulo (MZSP), Brazil, completing the publication of Myrmicinae types deposited in this institution. We adopted the traditional classification for Myrmicinae tribes to follow the already published catalogues regarding the Attini, Cephalotini, Dacetini and Solenopsidini and published catalogues in this series. In total, the present catalogue includes types of 213 nominal species, of which 169 are... |
