Simulium (Simulium) pingtungense, a new species of black fly (Diptera: Simuliidae) from Taiwan

「Abstract」: Simulium (Simulium) pingtungense sp.nov. is described from reared adult, pupal and mature larval specimens collected from Pingtung and Taitung, Taiwan, and is placed in the striatum species-group within the subgenus Simulium. This new species has close similarities in the female, male and pupa to S. (S.) quinquestriatum (Shiraki) from Taiwan, from which it is distinguished by the absence of the paired dorsal protuberances on the larval abdomen. This new species is very similar in the pupa and larva to S. (S.) wuzhishanense Chen from China but differs in the female by the size of the sensory vesicle relative to the third maxillary palpal segment and in the male by the number of large upper eye-facets.
