Taxonomic revision of tuberosum species-group of Simulium (Simulium) in Sabah and Sarawak, Malaysia (Diptera: Simuliidae) (original) (raw)

Abstract

In Sabah and Sarawak, Malaysia, six black fly species (two known and four new) are placed in the tuberosum species-group of the subgenus Simulium (Simulium) Latreille s. str. The male, pupa and mature larva of S. (S.) aeneifacies Edwards are described for the first time, S. (S.) sabahense Smart and Clifford is revised, and all the four new species are described. All the six species are morphologically very similar to one another and endemic to Borneo, thus suggesting an intra-insular speciation which has been so far known to occur very rarely in the tuberosum species-group.
