A new black fly species, Simulium (Nevermannia) subratai sp. nov., is described on the basis of female, pupal and larval specimens collected from Darjeeling, India. This new species is assigned to the feuerborni species-group of the subgenus Simulium (Nevermannia), and is characterized by the entirely yellow female thorax and the larval abdomen without any colored markings. This is the first re...

Three onchocerciasis vectors are recognized in Guatemala: Simulium ochraceum, Simulium metallicurn, and Simulium callidum (1); but the most important species is S. ochraceum. Its larvae generally breed in streams that carry a small volume of water and run under a canopy of dense vegetation, but that move swiftly because of the steep slopes of the foothills through which they fall. The larvae oc...

Simulium (Gomphostilbia) laosense sp. nov. is described based on adults, pupae, and mature larvae from Laos. This new species is placed in the Simulium batoense species-group of the subgenus Gomphostilbia Enderlein. It is characterized by the pupal gill with eight filaments arranged as 3 + 3 + 2 from dorsal to ventral, of which an inner filament of the ventral pair is slightly longer than its c...

Simulium (Simulium) kisapense sp. nov. is described on the basis of reared adult, pupal, and larval specimens collected from Langkawi Island, Peninsular Malaysia, and placed in the multi-striatum species-group in the subgenus Simulium. This new species is characterized by the bare basal section of the female radial vein, the male ventral plate with setae, the eight pupal gill filaments divergen...

Two new black fly species, Simulium (Gomphostilbia) brinchangense and S. (G.) tanahrataense, are described on the basis of reared adult females, males, pupae and larvae from Cameron's Highlands, Peninsular Malaysia. These new species are assigned to the asakoae species-group within Simulium (Gomphostilbia) and taxonomic notes are given to distinguish each new species from six known species in M...

BACKGROUND & OBJECTIVES Black flies (Diptera: Simuliidae) are ecologically and medically important insects. Female adults of black flies are the solitary vectors of river blindness (onchocerciasis) and their larvae play a vital role in stream ecosystem. This study examined the distribution of black flies in the Oriental region and analyzed the phylogenetic relationship of the subgenus Gomphosti...

This study was carried out in July 2016 Camili (Macahel) which is Turkey's first and only biosphere reserve area. The aims of this were to investigate the Simuliidae species some streams Valley, identify “reference site” are important for Water Framework Directive (WFD), determine ecological characteristics studied sites according System A B Classification explore relationship between recorded ...
