Eight new species of Drosophila, (Scaptodrosophila) diana, (Sc.) parapsychotriae, (Sc.) amydriae, (Sophophora) gorokaensis, (Drosophila) wauana, (D.) mucunae, (D.) spinula, and (D.) quadriserrata, are described from Morobe Province, Papua New Guinea. Five of them, amydriae, wauana, mucunae, spinula, and quadriserrata, appear to be associated with freshly decayed flowers ; in the other three this relationship is less clear. Among the four species belonging to the subgenus Drosophila, spinula frequents many kinds of flowers but was bred only from Mucuna and two species of Ipomoea. This latter host is shared by the melanogaster group species, D. elegans. D. (Sc.) hibisci was reared from Hibiscus esculentus. In the four papers of this series we have described 37 new species, 23 of which belong to the subgenus Scaptodrosophila. Of the latter, nine were reared from decayed inflorescences. Three more species of this subgenus, plaua, metatarsalis and scaptomyzoidea, were bred in such sites. We conclude that flowers, particularly of monocotyledons, are important natural breeding substrate for flies of the subgenus Scaptodrosophila.
