“…Based on this effect, our models were built to take into account the historical relationship among subfamilies and the similarity in their niches due to their shared history (Skidmore 1985, Carvalho 1989, Couri & Carvalho 2003, Nihei & Carvalho 2007). …”

-The distribution of muscid species (Diptera) in grasslands fragments of southern Brazil was assessed using null models according to three assembly rules: (a) negatively-associated distributions; (b) guild proportionality; and (c) constant body-size ratios. We built presence/absence matrices and calculated the C-score index to test negatively-associated distributions and guild proportionality based on the following algorithms: total number of fi xed lines (F L ), total number of fi xed columns (F C ), and the effect of the average size of the populations along lines (W) for 5000 randomizations. We used null models to generate random communities that were not structured by competition and evaluated the patterns generated using three models: general, trophic guilds, and taxonomic guilds.All three assembly rules were tested in each model. The null hypothesis was corroborated in all F L X F C co-occurrence analyses. In addition, 11 analyses of the models using the W algorithm showed the same pattern observed previously. Three analyses using the W algorithm indicated that species cooccurred more frequently than expected by chance. According to analyses of co-occurrence and guild proportionality, the coexistence of muscid species is not regulated by constant body size ratios. In fl ies of the grasslands, no rule was identifi ed. Yet, a consensus did emerge from our analyses: species co-occur more frequently than expected by chance, indicating that aggregation is a recurring phenomenon among fl ies with saprophagous adults and predatory larvae. Therefore, competition does not seem to play an important role in the determination of muscid assemblages in the grasslands in Southern Brazil.

“…Currently, the phylogeny of Muscidae has been studied by CARVALHO (1989b) and more recently by COURI & CARVALHO (2003). The family certainly constitute a monophyletic group (HENNIG 1965, MCALPINE 1989, MICHELSEN 1991 but has included groups that are doubtfully monophyletic (CARVALHO 1989b).…”

Pseudoptilolepis Snyder, 1949, a monophyletic Neotropical muscid genus of six species, is reviewed to include four new species, P. centralis sp. nov., P. chrysella sp. nov., P. crocina sp. nov. and P. elbida sp. nov. A taxonomic key is provided for the genus. The phylogenetic relationship among the studied species is: (P. centralis ((P. chrysella (P. fluminensis, P. fulvapoda)) (P. nudapleura (P. elbida (P. nigripoda, P. crocina))))). The geographic distribution of the species is also presented and briefly discussed.

“…Nome dado em homenagem a Charles Darwin, coletor dos dois parátipos fêmeas de P. confusus (Malloch) O cladograma aqui proposto apresenta Brachygasterina como grupo irmão de Palpibracus. Esta é a primeira vez que o relacionamento entre estes gêneros é testado pelo método filogenético uma vez que Carvalho (1989c) encontrou politomia para os gêneros de Reinwardtiini na única análise realizada utilizando estes gêneros. A relação entre Palpibracus e Brachygasterina é sustentada pela presença de uma cerda anterior no catepisterno (13 0 ).…”

“…O gênero está alocado na tribo Reinwardtiini, Azeliinae por apresentar haustelo com esclerotinização ciliada, tergito VI esclerotinizado em forma de âncora e esternito VIII inteiro (Carvalho 1989c). Carvalho (1989c) não encontrou nenhuma sinapomorfia para o gênero Palpibracus nem definiu seu relacionamento com os demais gêneros de Reinwardtiini, entretanto o autor já havia sugerido que o gênero fosse provavelmente monofilético (Carvalho 1989a).…”

ABSTRACT. Taxonomy, cladistics analysis and description of a new species of Palpibracus Rondani (Diptera, Muscidae). Palpibracus Rondani is a Muscidae genus with 16 species, including P. darwini sp. nov. described from male specimens from Concepción, Chile. A cladistic analysis was performed based on 31 adult morphological characters and using 12 species as outgroup. This analysis shows Palpibracus as a monophyletic genus whose sister-group is Brachygasterina Malloch. The relationship among Palpibracus species was: (P. veneris ((P. albuquerquei (P. peruvianus, P. trivittatus)) (P. fasciculatus, P. nigriventris)) ((P. spicatus, P. uvivittatus) (P. lancifer (P. darwini sp. nov. (P. chilensis, P. confusus (P. pilosus (P. similis (P. separatus, P. carvalhoi)))))))). Palpibracus apicalis Malloch was placed tentatively in Psilochaeta Stein. A key to species of Palpibracus is also provided.
