摘要

Simulium (Gomphostilbia) taitungense sp. nov. is described on the basis ofreared adult, pupal and mature larval specimens collected from Taitung, Taiwan. This newspecies is placed in the ceylonicum species-group within the subgenus Gomphostilbia and isdistinguished from related known species by the characteristic colour markings on the ventralsurface of the head capsule and on the dorsal surface of the abdomen in the larva. The maleof Simulium (Gomphostilbia) tuenense Takaoka, which was originally described from apharate pupa and a larva, is described for the first time; the association of the adult stagewith the larval stage was confirmed by the comparison of the sequences of the mitochondrial16S rRNA gene; this species is also placed in the ceylonicum species-group.
