“…The larvae and pupae of these species were collected from submerged deciduous leaves and roots and leaves of the streamside vegetation. S. cuasiexiguum was known from northern Goiás and Mato Grosso states, collected from small to medium-sized (10-100 m), fastflowing rivers (Shelley et al 2001). S oyapockense s.l.…”

During studies on the taxonomy of the Simuliidae of Brazil, a new species of Simulium was found. Full descriptions of the adults and pupae of this species are described here, its affinities with other species are discussed and its distribution, biology, and medical importance in Brazil are recorded.Key words: Simuliidae -Neotropical region -taxonomy -Simulium lobatoi -onchocerciasis -Mato Grosso -Goiás -BrazilThe discovery of several onchocerciasis foci in Central and South America has greatly contributed to our present knowledge of the systematics of Simuliidae in the Neotropical Region. In Brazil, the disease was first discovered 30 years ago in the states of Roraima and Amazonas (Shelley 1988) and, more recently, in Minaçu, state of Goiás (Maia-Herzog et al. 1999). Several revisionary studies on the epidemiology and dispersal of this disease have been published in the last decade (Py-Daniel 1997, Shelley et al. 1997, 2001a, Shelley 2002 together with the description of several new species and species complexes, as collecting efforts and taxonomic research continue on this morphologically homogeneous group (e.g. Coscarón et al. 1992, Charalambous et al. 1996, Hamada & Adler 1998a, b, 1999, Hamada 2000, Strieder & Coscarón 2000, Strieder & Py-Daniel 2000, Shelley et al. 2001b, Hamada et al. 2003. Further collecting of simuliids in the states of Mato Grosso and Goiás has revealed the presence of a new species, which is described in this paper. MATERIALS AND METHODSThe techniques for collection, dissection, and measurements of specimens as well as the terminology used in the species description are those detailed in Shelley et al. (1997Shelley et al. ( , 2000Shelley et al. ( , 2002. Images illustrating the morphology were obtained directly from the specimens using a Synoptics composite image analysis system (Shelley et al. 2000) and have been stored on CDs in The Natural History Museum, London (BMNH). Type specimens have been deposited in the Entomology Departments of the BMNH and the Oswaldo Cruz Institute (IOC), as indicated in material examined. Head -Dichoptic with dark red eyes and nudiocular area well developed (Fig. 1). Frons, clypeus, and occiput black, with silvery grey pruinosity; clypeus and frons covered with semi-recumbent brown hairs. Mouthparts and maxillary palps dark brown. Antennae with scape and pedicel yellowish brown, rest of flagellum dark brown. Cibarium with well developed, sclerotised cornuae and without teeth (Fig. 2). Thorax -Scutum dark brown with evenly arranged, recumbent, whitish setae, interspersed with fine, semi-recumbent brown setae; posterior margin with long dark hairs. Scutal pattern varying slightly with illumination. With anterior illumination, thorax dark brown with 1+1 submedian, white vittae, beginning near anterior border of scutum and curving towards mid line in anterior fourth of scutum from where they diverge to lateral margins, terminating at a point two thirds of length of scutum; 1 median, fine, vitta beginning on anterior margin and running in a straight line for...

Black flies have medical importance because some species are vectors of the Onchocerciasis and Mansonelosis, nevertheless, their ecology and potential use as bioindicators is still poorly studied in the Neotropical Region. In Brazil, bioindicators use is strongly focused in a multimetrical ecological index approach; this way, we investigated the black fly spatial distribution, in relation to abiotic factors correlated to water quality, to provide baseline information for their utilization as standalone indicators of lotic systems integrity. We have tested the hypothesis that environmental changes related to urbanization, lead to decreased abundance and loss in the number of species of the black fly fauna. The sampling was conducted in 10 urban and 10 preserved streams during the dry season (August-September) of 2012, in the mountainous region of Teresópolis, State of Rio de Janeiro, Brazil. The streams were characterized for their environmental integrity conditions and physico-chemical properties of water. In each stream, five different rapid points were sampled in a section of 50 meters, 10 meters apart from each other. The black flies were sampled with a kick-net sampler on rocky substrates. The material was separated and the larvae were sorted in morphotypes, and later, the final instar specimens were dissected and identified with the help of taxonomical literature at species level. A total abundance of 488 larvae from nine species were collected, 5 (1.02 %) in extremely impacted streams, 470 (96.31 %) in intermediate streams and 13 (2.66 %) in preserved streams. The visual evaluation (HII) differed in relation to the water physico-chemical evaluation, in which more variation in the characterization of the sampling sites was observed. In Canonical Correspondence Analysis Simulium subpallidum, S. inscrustatum and S. pertinax were significantly associated with intermediate values of most of the variables, and then to intermediate impacted sites. On the other hand, Lutzsimulium hirticosta, S. subnigrum and Simulium sp. A were associated to low values of chemical variables, and then to more preserved sites. Most studies on the bioindicator potential of Simuliidae have suggested an approach to agricultural impacts, while our results, on the other hand, showed that Simuliidae species were present in streams with intermediate urban pollution impacts, but absent in heavily impacted sites. Thus, our data suggested that some species are associated to more pristine breeding sites, such as L. hirticosta and Simulium sp. A, while others may be good bioindicators of moderately impacted streams, such as S. pertinax, S. subnigrum and S. subpallidum. Rev. Biol. Trop. 63 (3): 683-693. Epub 2015 September 01.
