A new species of Nepenthosyrphus De Meijere, 1932 (Diptera: Syrphidae), reared from flasks of pitcher plants (Nepenthaceae) is described from Indonesia. It is closely related to the Nepenthosyrphus oudemansi de Meijere, 1932 but can be distinguished, in both sexes, by the colour pattern of the abdomen and additionally in the males, by characters of the genitalia. Examination of the male genitalia may reveal many more species in this genus than the five currently recognised. Finally, the puparium of the new species is compared with that of the N. oudemansi from which it differs in the form of the unusual sclerotised and spinose lappets of the anal segment and the length of the spiracles of the posterior respiratory process.
