2. New synonymy to Simulium ( Inaequalium ) diversibranchium Lutz, with comments on the Inaequale species-group (Diptera, Simuliidae)
ABSTRACT Simulium (Inaequalium) Coscarón and Wygodzinsky, 1984 is a homogeneous subgenus widely spread on the Neotropical Region, which the adults can only be reliably identified from linked-reared specimens. Despite many revisionary works only a single character of the pupal gill separates Simulium diversibranchium Lutz, 1910 from S. mariavulcanoae Coscar�

3. Description of microsporidia in simulids: molecular and morphological characterization of microsporidia in the larvae of Simulium pertinax Kollar (Diptera: Simuliidae)
IntroductionMicrosporidia constitute the most common black fly pathogens, although the species' diversity, seasonal occurrence and transmission mechanisms remain poorly understood. Infections by this agent are often chronic and non-lethal, but they can cause reduced fecundity and decreased longevity. The objective of this study was to identify microsporidia

4. Dípteros hematófagos (Culicidae, Psychodidae, Simuliidae) em fragmento defloresta sob impacto de barragem na fronteira dos estados do Rio Grande do Sul e Santa Catarina, Brasil
O estudo de dípteros de importância médica em áreas afetadas pelas construções de barragens é muito importante, devido à possibilidade de ocorrência de doenças transmitidas por essas espécies. As coletas foram realizadas entre 2010 e 2011 em uma área sob o impacto de uma barragem no Rio Uruguai, na fronteira entre os estados do Rio Grande do Sul

5. Outstanding insecurities concerning the use of an Ov16-based ELISA in the Amazonia onchocerciasis focus
In a recent issue of Memórias do Instituto Oswaldo Cruz, published in Rio de Janeiro in February 2014 (109: 87-92), Adami et al. have published a survey reporting Mansonella parasite prevalence in the Amazon Region. This report makes a useful contribution to the existing knowledge of filarial parasite distribution within the Amazon area, parasite prevalence

6. Fauna of Simuliidae (Diptera) from the state of Espírito Santo, Brazil: distribution, new records and list of species
Fauna of Simuliidae (Diptera) from the state of Espírito Santo, Brazil: Distribution, new records and list of species. The fauna of Simuliidae in Brazil is composed of 87 species, 17 of which are recorded from the state of Espírito Santo. Entomological collections were carried out in 2010-2011 with the objective of increasing the knowledge of the species r

7. Simulium (Chirostilbia) brunnescens (Diptera: Simuliidae) - new species from the Brazilian cerrado, Manso Dam, state of Mato Grosso, Brazil
A new species of Simuliidae, Simulium (Chirostilbia) brunnescens, was discovered at Chapada dos Guimarães, state of Mato Grosso, Brazil, and nearby municipalities (Paranatinga, Rosário do Oeste and Nobres). This species is described here based on the adults, pupae and larvae. This species is closely related to Simulium (C.) subpallidum Lutz, but could be d

8. Evolution of insecticide resistance in non-target black flies (Diptera: Simuliidae) from Argentina
Black flies, a non-target species of the insecticides used in fruit production, represent a severe medical and veterinary problem. Large increases in the level of resistance to the pyrethroids fenvalerate (more than 355-fold) and deltamethrin (162-fold) and a small increase in resistance to the organophosphate azinphos methyl (2-fold) were observed between 1

9. Ampliação do nicho como consequência da co-existência: um estudo de caso
Variações espaço-temporal na dieta, na amplitude e na sobreposição de nicho foram estudadas para duas espécies de Characidium de três localidades distintas de um riacho costeiro da região Neotropical, considerando-se as estações seca e chuvosa. As alterações sazonais na dieta foram restritas à presença/ausência de itens vegetais nos conteúdos

10. Diversity and microdistribution of black fly (Diptera: Simuliidae) assemblages in the tropical savanna streams of the Brazilian cerrado
We describe the abiotic factors affecting the distribution of black flies at a microhabitat scale, rather than at the regional scale usually present in the literature on the Neotropics. Black fly larvae were sampled from the Tocantins River and three tributaries, located in the Brazilian savanna (state of Tocantins, Brazil) during six bi-monthly sampling per

11. The phylogeny of Simulium (Chirostilbia) (Diptera: Simuliidae) and perspectives on the systematics of the genus in the Neotropical Region
Recently, knowledge of Neotropical Simuliidae has been accumulating quickly. However, information about supra-specific relationships is scarce and diagnoses of Simulium subgenera are unsatisfactory. To investigate the relationships among Simulium (Chirostilbia) species and test the subgenus monophyly, we performed a cladistic analysis. The ingroup included a

12. Simulium (Psilopelmia) virescens, a new black-fly species (Diptera: Simuliidae) from the southwestern region of the state of Bahia, Brazil
The last-instar larva, pupa, male and female of Simulium virescens sp. nov. are described and illustrated. This species has a peculiar larva, which has an elongated head capsule and light-green colour. The first thoracic segment has tubercle on its dorsal region and the third thoracic segment has one pair of tubercles; the first to the fourth abdominal segme
