| Polytene chromosomes banding patterns of ten of the 16 species of the Neotropical annulimana group of Drosophila were used to propose phylogenetic relationships among species. Drosophila annulimana chromosomes were used as the standard sequence and the most parsimonious series of changes (paracentric inversions) were considered. In some cases, intermediate hypothetical rearrangements were proposed to explain the sequences present in a given species. A total of 47 paracentric inversions were detected, most of them (44.7%) in chromosome 4. Three subgroups, partially coincident with those previously proposed based on morphological and karyotypical analyses, were classified as: 1) annulimana subgroup (Drosophila annulimana, D. aracataca, D. aragua, and D.... |

| Abstract Rhinoleucophenga pallidaHendel, 1917 (type species of the genus) is redescribed based on its female holotype and a male from a nearby locality, and Rhinoleucophenga obesa (Loew, 1872) on its two syntypes, which are designated as the male lectotype and a female paralectotype. Both are valid species. A proposal is made to establish the genus Pseudophortica Sturtevant, 1918 (type species R. obesa), a junior synonym of Rhinoleucophenga, to subgenus rank and include all species of Rhinoleucophenga described or redescribed from males except R. pallida, which is unique in having a remarkable pedunculate surstylus, among other differences. The North American R. obesa is compared to its closest sibling, the South American species Rhinoleucophenga gigantea... |

| Abstract Drosophila butantan sp. nov., a species belonging to the guarani group and closely related to Drosophila nigrifemur from Bolivia, is described based on a female, and some of its offspring, collected at the forest reserve of the Instituto de Biociências da Universidade de São Paulo, Cidade Universitária "Armando de Salles Oliveira", São Paulo City, state of São Paulo, Brazil. Although externally similar, the two apparently forest-dwelling species can be told apart by having distinct oviscapt valves and spermathecal introverts and tips. Accordingly, a proposal is made to also include D. nigrifemur, a previously unassigned species, in the guarani group. The two species seem to be also related to Drosophila alexandrei and Drosophila guaraja as... |

| ABSTRACT Drosophila monsterae sp. nov. is described from 11 males and 13 females collected from the inside of closed inflorescences of Monstera lentii (Araceae) at 1810 m altitude in the Forest Reserve of Cerro de La Carpintera, Canton La Unión, Province of Cartago, Costa Rica. Although flies have been seen wandering and copulating inside the floral chambers of closed inflorescences during the floral female phase, eggs or larvae have not yet been found either in the spathe or in the fleshy spadix. The new species is related to Drosophila tristani Sturtevant, 1921, from San José, Costa Rica, from which it differs mainly by having smaller slightly circular compound eyes, distinctly broader genae (cheek index ca. 2.4 vs 5 in D. tristani), and the inner... |

| Drosophila nappae sp. nov. , belonging to the subgroup I of the Drosophila tripunctata species group of the subgenus Drosophila, is described from flies of one strain established from several females collected from July 1994 through April 1995 at Morro Santana, Porto Alegre, state of Rio Grande do Sul, Brazil. This species has been misidentified during the past fifty years as Drosophila angustibucca (sensu Frota-Pessoa, 1954; non Duda, 1925, described from Costa Rica). Illustrations of male and female terminalia are also provided. |

| Drosophila boraceia sp. nov. is described from a single male specimen collected at the Estação Biológica de Boracéia, Salesópolis, state of São Paulo, Brazil. At first inspection it looks like a species of Drosophila belonging to the fasciola subgroup of the repleta group, mainly because of the fasciola-like pattern of fused spots on the thorax. However, mostly due to the quite distinct structures of the male terminalia, it seems to be more similar to one ungrouped and also spot-thoraxed South American species, Drosophila atalaia Vilela & Sene, 1982. Illustrations of the terminalia are also provided. |

| Drosophila pauliceia sp. nov., a spot-thoraxed species closely related to Drosophila boraceia Vilela & Val, 2004, is described from flies collected in an urban remnant of the montane Atlantic Forest located at the Cidade Universitária "Armando de Salles Oliveira", São Paulo city, state of São Paulo, Brazil. The two forest-dwelling species can be externally distinguished mainly by having a different pattern of thoracic spots. A new group of spotted flies (peruensis group) is proposed to include them, in addition to Drosophila peruensis Wheeler, 1959, from Urubamba River, Peru, and Drosophila atalaia Vilela & Sene, 1982, from Brazil and Argentina. To facilitate comparisons, illustrations of the male and female terminalia of the new species... |

| ABSTRACT Two new species of Drosophilidae from Uruguay are described and illustrated: Drosophila montevidensis sp. nov. (Holotype male in MZSP: Facultad de Agronomía, Universidad de la República, Montevideo city, Department of Montevideo), and Scaptomyza pipinna sp. nov. (Holotype male in MZSP: Sarandí del Consejo, near north shore of Laguna de Castillos, Department of Rocha). The former species belongs to the D. tripunctata group and is sibling to Drosophila nappae Vilela, Valente & Basso-da-Silva, 2004, differing mainly in characters of the aedeagus. The latter is closely related to Scaptomyza striaticeps Wheeler & Takada, 1966, from which it can be distinguished by color and terminalia characters. The new Drosophila species was successfully... |

| This study investigates the species richness and abundance of Drosophila Fallén, 1823 attracted to dung and carrion baited pitfall traps in natural areas with heterogeneous habitats at the Sierra de Minas, Eastern Serranías, southeastern Uruguay. Collecting was carried out on a monthly basis (May 2002 through April 2003). Drosophilids accounted for 0.84% (n = 131) and 3.61% (n = 158) of the Diptera collected from dung (n = 15,630) and carrion (n = 4,382) pitfall traps, respectively. A total of 12 species were identified, 11 of which belong to the subgenus Drosophila (the richest) and one to the subgenus Sophophora Sturtevant, 1939. Over 90% of the Drosophila specimens collected belong to five species of the subgenus Drosophila, namely D. gaucha Jaeger... |
