New species of Dilobitarsus Latreille with tetra-tuberculated pronotum (Coleoptera, Elateridae, Agrypninae). Four species of Dilobitarsus Latreille, 1834, D. angulosus sp. nov. (Brazil: São Paulo, Rio de Janeiro), D. bellus sp. nov. (Peru), D. nigrus sp. nov. (Argentina) and D. thoraconstrictus sp. nov. (Bolivia) are described, and D. quadrituberculatus Candèze, 1857 is redescribed. Diagnostic characters of all studied species are illustrated and new records for D. quadrituberculatus are included. A key to Dilobitarsus species from the Neotropical Region is also presented. |

El oso melero (Tamandua tetradactyla) pertenece a la familia Myrmecophagidae del superorden Xenarthra. La fragmentación del hábitat, la caza local y el mascotismo, lo ubican en la categorización "potencialmente vulnerable" en Argentina. Para la aplicación a futuro de protocolos de biotecnología reproductiva en programas de manejo y conservación de gametos se realizaron disecciones anatómicas, estudios histológicos y de morfometría espermática (mediante microscopia óptica y electrónica) en tractos reproductores de 5 hembras y 4 machos. La diferenciación de la genitalia externa entre sexos resulta dificultosa: las hembras presentan una hendidura longitudinal y los machos presentan un orificio terminal en la punta del pene. El pene, contiguo al ano, está... |

A new genus, Pentatomiana, and a new species, P. beckerae, are described, based on specimens from Rio de Janeiro and Santa Catarina States, Brazil. Brachyptery is present in the males of the new species. Pentatomiana gen. nov. is compared with Lojus McDonald, 1982, which also presents brachyptery in one of the species, but in females. Illustrations of male and female external genitalia are provided. |

Megalobulimus K. Miller, 1878 is a genus of land snails that includes the largest living snails in the Neotropics. The main goal of this paper was to review all species of Megalobulimus that have a red lip, and which are distributed in Peru. We carried out a detailed description of their shells and soft parts, and conducted a multivariate analysis on their shells and geographic distribution. There are two species reported from Peru, Megalobulimus capillaceus (Pfeiffer, 1855) and Megalobulimus separabilis (Fulton, 1903). Megalobulimus capillaceus is known to occur in three regions - San Martín, Huánuco and Cusco - but the Cusco population is undoubtedly different from all remaining populations, and is recognized herein as a new species, Megalobulimus... |

Runibia Stål, 1861 is redescribed, as well as the species R. dallasi Rider, 1998, R. decorata (Dallas, 1851), R. discoidea (Fabricius, 1787), R. euopta (Walker, 1867) and R. perspicua (Fabricius, 1798). A new species, R. caribeana, is described from Virgin Islands. Strachia alligata Walker, 1867, R. decorata var. alligata, and R. picturata Breddin, 1904 were considered junior synonyms of R. decorata. Lectotypes of R. dallasi, R. euopta and R. alligata were designated. Male and female genitalia for all species are described, except the phallus and ectodermal genital duct for R. dallasi. A key and a geographical distribution map are also provided. |

Brachystethus Laporte, 1832 is revised. Brachystethus coxalis Breddin, 1904, B. cribrus (Fabricius, 1781), B. geniculatus (Fabricius, 1787), B. improvisus Breddin, 1905, B. rubromaculatus Dallas, 1851, B. signoreti Stål, 1872, B. tricolor Bolívar, 1879, B. vexillum Breddin, 1903 and B. vicinus Signoret, 1851 are redescribed based on morphological characters, with emphasis on genitalia of both sexes. A new species, B. schuhi, from Guyana, is described, and B. discolor (Walker, 1867), incertae sedis, is removed from the genus. Illustrations and a key for species of Brachystethus are provided. |

En estudios realizados en el bosque nublado Intillacta, provincia de Pichincha, Ecuador, y en la Cordillera de los Guacamayos, provincia de Napo, Ecuador, se encontró una nueva especie de Drosophila. En base a estudios de la morfología de la genitalia masculina, se propone que, Drosophila intillacta sp. nov. pertenece al grupo Drosophila annulimana. Así mismo, se reporta Drosophila tarsata Schiner, 1868, capturada en la Cordillera de los Guacamayos, como un nuevo registro para el país. |
