Black flies (Diptera: Simuliidae) of the Special Province of Aceh, Indonesia.

The black fly fauna of the Special Province of Aceh, Indonesia, was surveyed in 24 streams in 5 regencies, from 7 to 13 June 1998. Ten species were identified, Simulium (Nevermannia) aureohirtum Brunetti, S. (Gomphostilbia) duolongum Takaoka & Davies, S. (G.) sheilae Takaoka & Davies, S. (G.) sundaicum Edwards, S. (S.) nobile de Meijere, S. (S.) fenestratum Edwards, S. (S.) argyrocinctum de Meijere, S. (S.) nebulicola Edwards, S. (S.) iridescens de Meijere, and S. (S.) minangkabaum Takaoka & Sigit. These species are essentially oriental in distribution, because they belong to the 3 subgenera that are dominant groups in oriental or Palaearctic regions, or both.
