New systematic position of Itatingamyia Albuquerque (Diptera, Muscidae) based on molecular evidence, and description of the female of I. couriae

ABSTRACT ItatingamyiaAlbuquerque, 1979 is rare in collections, with only nine specimens preserved in museums. Two species are known, and their placement within Muscidae was never tested using molecular data. Here, we estimate the position of Itatingamyia within Muscidae with mitochondrial (COI) and nuclear (AATS, CAD, and EF1-α) markers using Maximum likelihood and Bayesian posterior probabilities as optimality criteria. According to our results, we propose to classify Itatingamyia as a Cyrtoneurininae. We also describe the previously unknown female and egg of Itatingamyia couriaeHaseyama and de Carvalho, 2011 and expand the known distribution of this species to the state of Minas Gerais, Brazil, through the discovery of 13 new specimens there. We also argue that Itatingamyia distribution is restricted to Atlantic Forest areas.

Taxonomic revision of the Neotropical stalk-eyed fly Plagiocephalus Wiedemann (Diptera, Ulidiidae, Ulidiinae)

ABSTRACT Plagiocephalus is a genus composed of three species mainly recognized by the males with stalked-eyes. Plagiocephalus lobularis is distributed from Northeastern Brazil to North of Argentina, P. latifrons is distributed from Mexico to Bolivia, and P. intermedius occurs in Costa Rica. We review the species of the genus, providing new diagnostic characters, an identification key, and new information on the terminalia of Plagiocephalus. Also, we update the geographic distribution of the species of the genus.

Wing shape is influenced by environmental variability in Polietina orbitalis (Stein) (Diptera: Muscidae)

ABSTRACT We measured variation and covariation in wing morphology in six populations of the fly Polietina orbitalis (Stein) (Diptera: Muscidae) to test for geographic morphological structure. Additionally, we examined the role of environmental variables in determining geographic variation in wing shape. We sampled five populations in the state of Paraná, southern Brazil (Colombo, Fênix, Guarapuava, Jundiaí do Sul and Ponta Grossa), and one in Paraguay (Mbaracayú). We choose 15 landmarks to describe the wing shape and size and 19 environmental variables to describe the local environmental conditions. Our results showed that P. orbitalis wing shape, but not size, varies geographically. A canonical variate analysis showed the existence of two clusters of populations based on wing shape. These groups compare populations in which the wing is slender with groups in which the wings are broad. These shape differences were correlated with variation in elevation, precipitation and temperature but were not allometric. Taken together, these results suggest that wing shape differences in P. orbitalis populations are due to a plastic response to local environmental conditions.

Seven new species of Limnophora Robineau-Desvoidy (Diptera: Muscidae) from Ecuador

ABSTRACTHere we describe seven new species of Limnophora from Ecuador: Limnophora bifasciatasp. nov. from Napo, Quito; Limnophora equatoriensissp. nov. from Zamora-Chinchipe, Zamora; Limnophora femurosetalissp. nov. from Zamora-Chinchipe, Zamora; Limnophora lamasisp. nov. from Zamora-Chinchipe, Zamora; Limnophora longivittatasp. nov. from Napo, Quito; Limnophora penaisp. nov. from Azuay, Cuenca and Limnophora polletisp. nov. from Napo, Quito.

Do fly parasites of bats and their hosts coevolve?speciation in Trichobius phyllostomae group (Diptera, Streblidae) and their hosts (Chiroptera, Phyllostomidae) suggests that they do not / Moscas parasitas de morcegos e seus hospedeiros co-evoluem?especiação do grupo Trichobius phyllostomae (Diptera, Streblidae) e seus hospedeiros (Chiroptera, Phyllostomidae) sugere que eles não fazem

We examined whether, like many parasite-host systems of coevolution, a group of obligate parasitic bat flies (Trichobius phyllostomae Kessel and related species) cospeciate with their hosts. We first did a cladistic analysis of the T. phyllostomae group and combined that analysis with a phylogenetic hypothesis from the literature for the Stenodermatinae bats. The cladistic analysis included, as outgroups, one species from each morphological group and complex of Trichobius Gervais, and one species from the following genera: Paratrichobius Miranda-Ribeiro, Megistopoda Macquart, Megistapophysys Dick & Wenzel, Neotrichobius Wenzel & Aitken, Speiseria Kessel and Strebla Wiedemann. The cladogram was rooted with a species of Strebla in the subfamily Streblinae. One cladogram was obtained and which found Trichobius to be polyphyletic. The phylogenetic hypothesis as follows: (Paratrichobius, (Neotrichobius, (Megistopoda, Megistapophysis)))) is the sister-group of the phyllostomae group and the following relationships within the ingroup, (((T. vampyropis Wenzel, Trichobius sp. 2) ((T. hispidus Wenzel, T. petersoni Wenzel) ((Trichobius sp. 1 (T. phyllostomae, T. brennani Wenzel))))). When we compared phylogenies through historical association analyses, cospeciation was uncommon, while host-switching was more common and better explained the association between the phyllostomae group and their bat hosts.

Nós examinamos, como em muitos sistemas parasito-hospedeiro de coevolução, se um grupo de moscas parasitas obrigatórias de morcegos (Trichobius phyllostomae Kessel e espécies relacionadas) coespecia com seus hospedeiros. Primeiro, nós fizemos uma análise cladística do grupo T. phyllostomae e combinamos a análise com a hipótese filogenética da literatura para os morcegos da subfamília Stenodermatinae. A análise cladística incluiu, como grupo-externo, uma espécie de cada grupo morfológico de Trichobius Gervais, e uma espécie dos seguintes gêneros: Paratrichobius Miranda-Ribeiro, Megistopoda Macquart, Megistapophysys Dick & Wenzel, Neotrichobius Wenzel & Aitken, Speiseria Kessel e Strebla Wiedemann. O cladograma foi enraizado com a espécie de Strebla da subfamília Streblinae. Um cladograma foi obtido e no qual encontramos Trichobius como polifilético. A hipótese filogenética a seguir: (Paratrichobius, (Neotrichobius, (Megistopoda, Megistapophysis)))) é grupo-irmão do grupo phyllostomae e a relação dentro do grupo-interno a seguir, (((T. vampyropis Wenzel, Trichobius sp. 2) ((T. hispidus Wenzel, T. petersoni Wenzel) ((Trichobius sp. 1 (T. phyllostomae, T. brennani Wenzel))))). Quando comparamos as filogenias através de análises de associação histórica, co-especiação foi pouco comum, enquanto colonização de um novo hospedeiro foi mais comum e explicou melhor a associação netre o grupo phyllostomae e seus hospedeiros.

Assembly rules in Muscid Fly assemblages in the grasslands Biome of Southern Brazil

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 fixed 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 co-occurred 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 identified. 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 flies 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.

Synanthropy and ecological aspects of Muscidae (Diptera) in a tropical dry forest ecosystem in Colombia / Sinantropía y algunos aspectos de la ecología de Muscidae (Diptera) en un ecosistema de bosque seco tropical en Colombia

The synanthropic index and other ecological aspects of the Muscidae family were evaluated through simultaneous monthly sampling in three different environments (urban, rural and forest) using van Someren-Rydon traps baited with human faeces, chicken viscera and decomposing fish and onion. Four traps were set up in each environment (one per bait item) for 48 hours per month, with samples taken every 12 hours. A total of 5726 specimens were collected, belonging to 19 species and 13 genera. Brontaea normata (+99,9), Brontaea quadristigma (+96,9), Synthesiomyia nudiseta (+96,5), Ophyra aenescens (+96,2), Musca domestica (+95,7) and Atherigona orientalis (+93,8) had the highest synanthropic indices, showing a marked preference for human environments. The most abundant species were B. normata (24,31 percent), Biopyrellia bipuncta (20,60 percent) and Pseudoptilolepis nigripoda (15,82 percent), the latter two showed a preference for uninhabited areas. A total of 11 new records for Colombia were found: Ophyra aenescens, Cyrtoneuropsis pararescita, Morellia basalis, Neomuscina dorsipuncta, Biopyrellia bipuncta, Pseudoptilolepis nigripoda, Neomuscina instabilis, Neomuscina currani, Polietina orbitalis, Neomuscina pictipennis and Cyrtoneuropsis maculipennis. Except for the first four species, the remainder presented negative synantrophy indexes (from minor to major), which would allow to use them as ecological indicators of the disturbance degree of dry forests in Colombia.

Se evaluó el índice de sinantropía al igual que otros aspectos ecológicos de la familia Muscidae, mediante muestreos mensuales simultáneos en tres ambientes (urbano, rural y bosque), para lo cual se utilizaron trampas van Someren Rydon cebadas con excremento humano, vísceras de pollo, pescado y cebolla en descomposición. En cada zona se instalaron cuatro trampas (una por atrayente), durante 48 horas cada mes, realizando colectas cada 12 horas. Se colectaron 5726 ejemplares pertenecientes a 19 especies y 13 géneros. Brontaea normata (+99,9), Brontaea quadristigma (+96,9), Synthesiomyia nudiseta (+96,5), Ophyra aenescens (+96,2), Musca domestica (+95,7) y Atherigona orientalis (+93,8), presentaron los índices de sinantropía mas altos, mostrando una marcada preferencia por los ambientes humanos. Las especies más abundante fueron B. normata (24,31 por ciento), Biopyrellia bipuncta (20,60 por ciento) y Pseudoptilolepis nigripoda (15,82 por ciento), las dos últimas con preferencia por áreas deshabitadas. Se encontraron un total de 11 reportes nuevos para Colombia: Ophyra aenescens, Cyrtoneuropsis pararescita, Morellia basalis, Neomuscina dorsipuncta, Biopyrellia bipuncta, Pseudoptilolepis nigripoda, Neomuscina instabilis, Neomuscina currani, Polietina orbitalis, Neomuscina pictipennis y Cyrtoneuropsis maculipennis. Exceptuando las primeras cuatro especies, las restantes presentaron índices de sinantropía bajos (de menor a mayor), lo que permitiría usarlas como indicadores ecológicos del grado de perturbación de los bosques secos en Colombia.

Cordiluroides Albuquerque from Costa Rica: first records, descriptions and taxonomic changes (Diptera, Muscidae, Coenosiinae)

Cordiluroides Albuquerque is a genus of Neotropical Coenosiinae (Muscidae), known from six species. The genus is here recorded for the first time from Costa Rica, on the basis of three species: C. listrata Albuquerque, 1954, C. insularis (Willliston, 1896) and C. bistriata (Wulp, 1896) sp. rev.. We provide a key for the identification of these Costa Rican species, redescribe and illustrate their external morphological characters and terminalia. C. bistriata and C. vittifera (Stein, 1904) are both considered to be good species and are re-instated from the synonymy of C. insularis. The type material of C. listrata (Museu Nacional, Rio de Janeiro), of C. insularis and C. bistriata (The Natural History Museum, London) and of C. vittifera (Museum für Naturkunde, Humboldt-Universitãt zu Berlin) has been examined.

Fauna de Muscidae (Diptera) em três localidades do Estado do Paraná, Brasil, capturada por armadilha Malaise / Muscidae (Diptera) fauna from three sites of Parana State, Brazil, captured with Malaise trap

During two years, from August 1986 to July 1988, the entomofauna of some preserved areas of Parana State, southern Brazil, was sampled in a project called "Levantamento da Fauna Entomológica no Estado do Paraná (PROFAUPAR)". Specimens of Muscidae (Diptera) were sorted out from the material collected using Malaise traps in three of the eight sites sampled (Colombo, Ponta Grossa and Guarapuava) in the first year (August 1986 to July 1987). A total of 7,014 specimens of Muscidae was captured and 91 species were identified. Neodexiopsis flavipalpis Albuquerque was the most abundant species in Ponta Grossa (672 specimens) and in Guarapuava (332 specimens). For Colombo, the most abundant species was Neodexiopsis vulgaris Couri & Albuquerque (172 specimens). The highest richness of species and abundance were observed in Ponta Grossa (77 and 3,559 respectively). The total number of specimens and means values of capture were analyzed. Indices of diversity and evenness were used to discuss richness and dominance of species in each locality. Besides using ecological indices, species richness estimators were also used.

Dípteros fanídeos vetores de ovos de Dermatobia hominis em Campo Grande, Mato Grosso do Sul / Fanniid diptera vectors of Dermatobia hominis eggs in Campo Grande, MS, Brazil

Determinou-se a importância epidemiológica de dípteros Fanniidae na infestaçäo de mosca-do-berne, por meio da identificaçäo das espécies presentes, da determinaçäo daquelas utilizadas por Dermatobia hominis na veiculaçäo de seus ovos, bem como, pelo conhecimento da dinâmica populacional das espécies mais abundantes. Foram utilizadas cinco armadilhas iscadas com fígado bovino cru deteriorado e colocadas em uma mata ciliar margeada por uma área de pastagem com presença constante de bovinos. O estudo foi desenvolvido em uma área da Embrapa Gado de Corte, em Campo Grande, Estado de Mato Grosso do Sul, Brasil, localizada a 20º27'S e 54º37'W. A captura dos insetos foi realizada semanalmente durante o período de 09/08/1999 a 03/08/2000. Foi capturado um total de 40.629 moscas da família Fanniidae, pertencendo a cinco espécies do gênero Fannia: F. pusio, F. heydenii, F. bahiensis e F. longipila, e uma a ser identificada. A espécie mais freqüente foi F. pusio, com 63,20 por cento do total capturado, seguida de F. heydenii, com 28,82 por cento. Somente 0,44 por cento do total de fêmeas de F. heydenii (45 exemplares) capturadas, principalmente nos meses de agosto e setembro, portavam ovos de D. hominis e o número médio, por indivíduo, foi de 15,98±7,13. Observaram-se ovos de D. hominis apenas na regiäo abdominal dos vetores. F. heydenii predominou no período seco (maio a setembro) e início do período chuvoso do ano (outubro e novembro). O número de exemplares portando ovos de D. hominis foi maior no final do período seco do ano, o que explica a alta incidência deste parasito em bovinos nos meses de setembro e outubro

A preliminary analysis of insects of medico-legal importance in Curitiba, State of Parana

A survey of the carrion fauna was made at two sites in Curitiba, State of Parana, with the objective of describing the insects associed with carrion and setting up a preliminary data-base for medico-legal purposes in south Brazil. Vertebrate exclusion experiments were carried out in each season between 1994 and 1995 with a 250 g laboratory-bred rat (rattus norvegicus). Five stages of decomposition were identified: fresh, bloated, decaying, dry and adipocere-like. Some species showed seasonal and site preference and so could be used to identify the probable place and season where death took place. Sarconesia chlorogaster (Diptera, Calliphoridae) was restrited to an open field site and to cooler months. Hemilucilia semidiaphana (Diptera, Calliphoridae) and Pattonella resona (Diptera, Sarcophagidae) were restrited to the forest site and warmer months. Phaenicia eximia (Diptera, Calliphoridae) and Oxyletrum discicolle (Coleoptera, Silphidae) were present at both sites throughout the year and could be useful for population level analysis. Dissochaetus murray (Coleoptera, Cholevidae) was present throughout the year at the forest site and was associated with the adipocere-like stage. Ants played an important role producing post-mortem injuries to the carcasses. Insects of 32 species are reported as being useful in community level approaches.
