Two new black fly species, Simulium (Gomphostilbia) tekamense and Simulium (Gomphostilbia) jerantutense, are described based on adult females emerged from pupae in Peninsular Malaysia, and assigned to the binuanense subgroup of the batoense species-group in the subgenus Gomphostilbia. Simulium (G.) tekamense sp. nov. is characterized in the female by the subcosta with 0-2 hairs, and presence of...

Simulium Indicum Becher, a man-biting species, is reviewed in detail. The female of this species is redescribed. The male of Simulium nodosum Puri is described for the first time and supplementary notes on the female, pupa and larva are presented.

With the interruption of larva treatments done by OCP as part of onchocerciasis control in West Africa, Simulium came back in abundance in forest regions and savannah fertile valleys. In addition to the severe discom fort, nuisance by Simulium is in certain cases incompatible with land use. Since ground treatment of larval breading sites using insecticides is not always possible or efficient, i...

Species of the Simulium (Simulium) melanopus species-group in Sabah are taxonomically revised by examining type specimens of S. (S.) crassimanum S. (S.) laterale, and S. (S.) nigripilosum, all described from females by Edwards in 1933, and newly collected samples from the vicinity of Mt. Kinabalu. The females of these three species are redescribed, and their males and pupae are described for th...

The females, males, pupae, and larvae of two new species of Simulium are described and illustrated from a small stream 3950 m above sea level in the Lake Otún area of the Colombian Andes Mountains. Simulium (Pternaspatha) quimbayium n. sp. represents a 630-km northeastern extension of the distributional range of previously known members of the subgenus Pternaspatha, and Simulium (Psilopelmia) m...

On the basis of sex chromosome variation, three cytotypes of Simulium squamosum (Enderlein) (Diptera: Simuliidae) are described from Cameroon and Nigeria. Simulium squamosum A is the typical form as originally described by Vajime & Dunbar (1975) with chromosome I as the sex chromosome. It occurs throughout most of Cameroon and south-east Nigeria. A second cytotype, S. squamosum B, is described ...

We report cases of Simuliidae and Chironomidae living on Lachlania nymphs (Ephemeroptera). This is the first record of these associations in South America. Simulium exiguum (pupae and larvae), Simulium cuasiexiguum (larvae), Cricotopus sp. (larva) and Rheotanytarsus sp. (larva) were found associated with Lachlania nymphs. We believe that all of these associations can be classified as opportunis...

Simulium (Gomphostilbia) hiroyukii is described based on females, males, pupae and larvae collected in Mount Murud, Sarawak, Malaysia. This new species is assigned to the Simulium darjeelingense species-group of the subgenus Gomphostilbia, and is characterized by the darkened fore coxae and the pupal gill with eight long filaments, of which middle and dorsal triplets have elongated primary and ...

BACKGROUND The biting preference of Simulium vectors has been known to influence the distribution of Onchocerca nodules and microfilariae in human body. There is, however, variation in biting pattern of Simulium flies in different geographical locations. This study investigates the biting pattern on human parts by Simulium vectors along Osun river system where Simulium soubrense Beffa form has ...
